The Bazel team is happy to announce a new version of Bazel, [Bazel 0.19](https://github.com/bazelbuild/bazel/releases/tag/0.19.0).

This document lists the major changes since Bazel 0.18.

General changes
---------------

* The `--incompatible_expand_directories` flag will automatically expand directories in command lines. Design doc: https://docs.google.com/document/d/11agWFiOUiz2htBLj6swPTob5z78TrCxm8DQE4uJLOwM

* The `--loading_phase_threads` flag now defaults to `auto` (not 200, as was previously the case), which at the moment corresponds to the number of CPUs. This is appropriate for most users. However, if your sources reside on a network file system, increasing this value may yield better analysis-time performance when disk caches are cold.

Android
-------

* Fixed missing debug symbols when building native code with `--compilation_mode=dbg` that target Android ARM architectures by adding the `-g` flag.

C
---

* Added `--incompatible_disable_legacy_flags_cc_toolchain_api` to deprecate legacy `cc_toolchain` Starlark API for legacy CROSSTOOL fields. Tracking issue is bazelbuild#6434. Migration docs are on the bazel website.

* Runfiles in cc_test: the C runfiles library (`@bazel_tools//tools/cpp/runfiles`) can now create Runfiles objects for tests. See `//tools/cpp/runfiles/runfiles_src.h` (in the Bazel source tree) for documentation.

* :cc_binary link action no longer hardcodes `-static-libgcc` for toolchains that support embedded runtimes (guarded by `--experimental_dont_emit_static_libgcc` temporarily).

* The flag `--experimental_enable_cc_configuration_make_variables` is removed, use `--incompatible_disable_cc_configuration_make_variables` instead.

Java
----

* If the `--javabase` flag is unset, Bazel locates a JDK using the `JAVA_HOME` environment variable and searching the PATH. If no JDK is found `--javabase` will be empty, and builds targeting Java will not be supported. Previously Bazel would fall back to using the embedded JDK as a `--javabase`, but this is no longer default behaviour. A JDK should be explicitly installed instead to enable Java development.

Code Coverage
-------------

* LcovMerger was renamed to CoverageOutputGenerator.

* Faster coverage collection for gcc compiled C code can now be tested by enabling it with `--experimental_cc_coverage`.

Other Changes
-------------

* Add `--apple_compiler` and `--apple_grte_top options`. These provide the equivalent of --compiler / --grte_top for the toolchain configured in --apple_crosstool_top.

* There is now a `same_pkg_direct_rdeps` query function. See the query documentation for more details.

* Propagating remote errors to the user even if `--verbose_failures=false` is set.

* Add number of configured targets to analysis phase status output.

* Bazel will now check stderr instead of stdout to decide if it is outputting to a terminal. `--isatty` is deprecated, use `--is_stderr_atty` instead.

Future Changes
--------------

* None of the C related incompatible flags mentioned in the 0.18 release were flipped, they will be flipped in the next release (0.20). We have created tracking issues for all the relevant incompatible flags:
* [`--incompatible_disable_late_bound_option_defaults`](https://docs.bazel.build/versions/master/skylark/backward-compatibility.html#disable-late-bound-option-defaults): bazelbuild#6384
* [`--incompatible_disable_depset_in_cc_user_flags`](https://docs.bazel.build/versions/master/skylark/backward-compatibility.html#disable-depsets-in-c-toolchain-api-in-user-flags): bazelbuild#6383
* [`--incompatible_disable_cc_toolchain_label_from_crosstool_proto`](https://docs.bazel.build/versions/master/skylark/backward-compatibility.html#disallow-using-crosstool-to-select-the-cc_toolchain-label): bazelbuild#6382
* [`--incompatible_disable_cc_configuration_make_variables`](bazelbuild#6381): bazelbuild#6381
* [`--incompatible_disable_legacy_cpp_toolchain_skylark_api`](https://docs.bazel.build/versions/master/skylark/backward-compatibility.html#disable-legacy-c-configuration-api): bazelbuild#6380
* [`incompatible_disable_legacy_flags_cc_toolchain_api`](https://docs.bazel.build/versions/master/skylark/backward-compatibility.html#disable-legacy-c-toolchain-api): bazelbuild#6434

* In the 0.20 release the flags [`--incompatible_remove_native_git_repository`](https://docs.bazel.build/versions/master/skylark/backward-compatibility.html#remove-native-git-repository) and [`--incompatible_remove_native_http_archive`](https://docs.bazel.build/versions/master/skylark/backward-compatibility.html#remove-native-http-archive) will be turned on.

     86a8217:
     Temporarily restore processing of workspace-wide tools/bazel.rc
     file.

General changes

- New [bazelrc file list](https://docs.bazel.build/versions/master/user-manual.html#where-are-the-bazelrc-files).
  If you need to keep both the old and new lists of .rc files active
  concurrently to support multiple versions of Bazel, you can import the old
  file location into the new list using `try-import`. This imports a file if it
  exists and silently exits if it does not. You can use this method to account
  for a user file that may or may not exist

- [.bazelignore](https://docs.bazel.build/versions/master/user-manual.html#.bazelignore)
  is now fully functional.

- The startup flag `--host_javabase` has been renamed to
  `--server_javabase` to avoid confusion with the build flag
  `--host_javabase`.

Android

- The Android resource processing pipeline now supports persistence
  via worker processes. Enable it with
  `--persistent_android_resource_processor`. We have observed a 50% increase
  in build speed for clean local builds and up to 150% increase in build
  speed for incremental local builds.

C  

- In-memory package //tools/defaults has been removed (controlled by
  `--incompatible_disable_tools_defaults_package` flag). Please see
  [migration instructions](https://docs.bazel.build/versions/master/skylark/backward-compatibility.html#disable-inmemory-tools-defaults-package)
  and migrate soon, the flag will be flipped in Bazel 0.19, and the legacy
  behavior will be removed in Bazel 0.20.

- Late bound option defaults (typical example was the `--compiler` flag, when
  it was not specified, it’s value was computed using the CROSSTOOL) are removed
  (controlled by `--incompatible_disable_late_bound_option_defaults` flag).
  Please see [migration instructions](https://docs.bazel.build/versions/master/skylark/backward-compatibility.html#disable-late-bound-option-defaults)
  and migrate soon, the flag will be flipped in Bazel 0.19, and the legacy
  behavior will be removed in Bazel 0.20.

- Depsets are no longer accepted in `user_compile_flags` and `user_link_flags`
  in the C   toolchain API (controlled by
  `--incompatible_disable_depset_in_cc_user_flags` flag) affects C   users.
  Please see [migration instructions](https://docs.bazel.build/versions/master/skylark/backward-compatibility.html#disable-depsets-in-c-toolchain-api-in-user-flags)
  and migrate soon, the flag will be flipped in Bazel 0.19, and the legacy
  behavior will be removed in Bazel 0.20.

- CROSSTOOL is no longer consulted when selecting C   toolchain (controlled by
  `--incompatible_disable_cc_toolchain_label_from_crosstool_proto` flag).
  Please see [migration instructions](https://docs.bazel.build/versions/master/skylark/backward-compatibility.html#disallow-using-crosstool-to-select-the-cc_toolchain-label)
  and migrate soon, the flag will be flipped in Bazel 0.19, and the legacy behavior will be removed in Bazel 0.20.

- You can now use [`toolchain_identifier` attribute](bazelbuild@857d466)
  on `cc_toolchain` to pair it with CROSSTOOL toolchain.

- C   specific Make variables
  are no longer passed from the `CppConfiguration`, but from the C   toolchain
  (controlled by `--incompatible_disable_cc_configuration_make_variables` flag).
  Please see [migration instructions](https://docs.bazel.build/versions/master/skylark/backward-compatibility.html#disallow-using-c-specific-make-variables-from-the-configuration)
  and migrate soon, the flag will be flipped
  in Bazel 0.19, and the legacy behavior will be removed in Bazel 0.20.

- Skylark api accessing C  
  toolchain in `ctx.fragments.cpp` is removed (controlled by
  `--incompatible_disable_legacy_cpp_toolchain_skylark_api` flag).
  Please migrate soon, the flag will be flipped
  in Bazel 0.19, and the legacy behavior will be removed in Bazel 0.20.

- cc_binary link action no longer hardcodes
  `-static-libgcc` for toolchains that support embedded runtimes
  (guarded by [`--experimental_dont_emit_static_libgcc`](https://source.bazel.build/bazel/ /2f281960b829e964526a9d292d4c3003e4d19f1c)
  temporarily). Proper deprecation using `--incompatible` flags will follow.

Java

- Future versions of Bazel will require a locally installed JDK
  for Java development. Previously Bazel would fall back to using
  the embedded `--server_javabase` if no JDK as available. Pass
  `--incompatible_never_use_embedded_jdk_for_javabase` to disable the
  legacy behaviour.

- `--javacopt=` no longer affects compilations of tools that are
  executed during the build; use `--host_javacopt=` to change javac
  flags in the host configuration.

Objective C

- `objc_library` now supports the module_name attribute.

Skylark

- Adds `--incompatible_expand_directories` to automatically expand
  directories in skylark command lines. Design doc:
  https://docs.google.com/document/d/11agWFiOUiz2htBLj6swPTob5z78TrCxm8DQE4uJLOwM

- Support fileset expansion in ctx.actions.args(). Controlled by
  `--incompatible_expand_directories`.

Windows

- `--windows_exe_launcher` is deprecated, this flag will be removed
  soon. Please make sure you are not using it.

- Bazel now supports the symlink runfiles tree on Windows with
  `--experimental_enable_runfiles` flag. For more details, see
  [this doc](https://docs.google.com/document/d/1hnYmU1BmtCSJOUvvDAK745DSJQCapToJxb3THXYMrmQ).

Other Changes

- A new experimental option `--experimental_ui_deduplicate` has been added. It
  causes the UI to attempt to deduplicate messages from actions to keep the
  console output cleaner.

- Add `--modify_execution_info`, a flag to customize action execution
  info.

- Add ExecutionInfo to aquery output for ExecutionInfoSpecifier
  actions.

- When computing `--instrumentation_filter`, end filter patterns with
  "[/:]" to match non-top-level packages exactly and treat
  top-level targets consistently.

- Added the `bazel info server_log` command, which obtains the main Bazel
  server log file path. This can help debug Bazel issues.

- `aapt shrink` resources now properly respect filter configurations.

Incompatible changes:

  - Loading @bazel_tools//tools/build_defs/repo:git_repositories.bzl
    no longer works. Load @bazel_tools//tools/build_defs/repo:git.bzl
    instead.
  - If the same artifact is generated by two distinct but identical
    actions, and a downstream action has both those actions' outputs
    in its inputs, the artifact will now appear twice in the
    downstream action's inputs. If this causes problems in Skylark
    actions, you can use the uniquify=True argument in Args.add_args.
  - If the same artifact is generated by two distinct but identical
    actions, and a downstream action has both those actions' outputs
    in its inputs, the artifact will now appear twice in the
    downstream action's inputs. If this causes problems in Skylark
    actions, you can use the uniquify=True argument in Args.add_args.
  - Labels in C   rules' linkopts attribute are not expanded anymore
    unless they are wrapped, e.g: $(location //foo:bar)
  - If the same artifact is generated by two distinct but identical
    actions, and a downstream action has both those actions' outputs
    in its inputs, the artifact will now appear twice in the
    downstream action's inputs. If this causes problems in Skylark
    actions, you can use the uniquify=True argument in Args.add_args.
  - New bazelrc file list.
  - Windows: when BAZEL_SH envvar is not defined and Bazel searches
    for a suitable bash.exe, Bazel will no longer look for Git Bash
    and no longer recommend installing it as a Bash implementation.
    See issue bazelbuild#5751.
  - New bazelrc file list.

New features:

  - The aquery command now supports --output=text.
  - Java, runfiles: the Java runfiles library is now in
    @bazel_tools//tools/java/runfiles. The old target
    (@bazel_tools//tools/runfiles:java-runfiles) is deprecated and
    will be removed in Bazel 0.18.0.
  - Java, runfiles: the Java runfiles library is now in
    @bazel_tools//tools/java/runfiles. The old target
    (@bazel_tools//tools/runfiles:java-runfiles) is deprecated and
    will be removed in Bazel 0.19.0 (not 0.18.0, as stated earlier).

Important changes:

  - Allow @ in package names.
  - Remove support for java_runtime_suite; use alias() together with
    select() instead.
  - Python wrapper scripts for MSVC are removed.
  - [JavaInfo] Outputs are merged in java_common.merge().
  - Faster analysis by improved parallelization.
  - --experimental_shortened_obj_file_path is removed.
  - Introduce the --remote_cache_proxy flag,
    which allows for remote http caching to connect
    via a unix domain socket.
  - No longer define G3_VERSION_INFO for c   linkstamp compiles, as
    it was a duplicate of G3_TARGET_NAME.
  - Added support for Android NDK r17. The default STL is now
    `libc  `, and support for targeting `mips`, `mips64` and `ARMv5`
    (`armeabi`) has been removed.
  - Add aquery command to get analysis time information about the
    action graph.
  - Fixed compatibility with aar_import when using aapt2.  AAPT2 is
    now supported for Android app builds without resource shrinking.
    To use it, pass the `--android_aapt=aapt2` flag or define
    android_binary.aapt_version=aapt2.
  - Code coverage is collected for Java binaries invoked from sh_test.
  - java_common.compile creates the native headers jar accesible via
    JavaInfo.outputs.native_headers.
  - Deleting deprecated no-op flag --show_package_location
  - The JDK shipped with Bazel was updated to JDK10.
  - Rename the startup flag --host_javabase to --server_javabase to
    avoid confusion with the build flag --host_javabase
  - newly added options --experimental_repository_hash_file and
      --experimental_verify_repository_rules allow to verify for
    repositories
      the directory generated against pre-recorded hashes. See
    documentation
      for those options.
  - Removed the gen_jars output group
  - --subcommands can now take a "pretty_print" value
    ("--subcommands=pretty_print") to print the
    arguments of subcommands as a list for easier reading.
  - follow-up to
    bazelbuild@1ac359743176e659e9c7472
    645e3142f3c44b9e8
  - A rule error is now thrown if a Skylark rule implementation
    function returns multiple providers of the same type.
  - When using Bazel's remote execution feature and Bazel has to
    fallback to local execution for an action, Bazel used
    non-sandboxed
    local execution until now. From this release on, you can use the
    new
    flag --remote_local_fallback_strategy=<strategy> to tell Bazel
    which
    strategy to use in that case.
  - Execution Log Parser can now, when printing it out, filter the
    log by runner type
  - A rule error is now thrown if a Skylark rule implementation
    function returns multiple providers of the same type.
  - Removed the gen_jars output group
  - Removed the gen_jars output group
  - Set --defer_param_files to default to true.
  - Sort attribute lists in proto-form query output to fix
    non-deterministic genquery output.
  - Replace 0/1 with False/True for testonly attribute
  - bazel now supports a .bazelignore file specifying
      directories to be ignored; however, these directories still
      have to be well founded and, in particular, may not contain
      symlink cycles.
  - Add more detailed reporting of the differences between startup
    options.
  - update data binding to 3.2.0
  - For Android incremental dexing actions, Bazel now persists its
    DexBuilder process across individual actions. From our
    benchmarks, this results in a 1.2x speedup for clean local builds.
  - The standard `xcode_VERSION` feature now always uses exactly two
    components in the version, even if you specify `--xcode_version`
    with
    more or fewer than two.
  - A rule error will be thrown if a Skylark rule implementation
    function returns multiple providers of the same type. Try the
    `--incompatible_disallow_conflicting_providers` flag to ensure
    your code is forward-compatible.
  - Removed notion of FULLY_STATIC linking mode from C   rules.
  - In documentation, we've renamed Skylark into Starlark.
  - Execution Log Parser can now, when printing it out, reorder the
    actions for easier text diffs
  - Linkstamps are no longer recompiled after server restart.
  - Use VanillaJavaBuilder and disable header compilation in
    toolchain_hostjdk8. The default toolchain will soon drop
    compatibility with JDK 8. Using a JDK 8 host_javabase
    will only be supported when using 'VanillaJavaBuilder' (which
    does not support Error Prone,
    Strict Java Deps, or reduced classpaths) and with header
    compilation disabled.
  - In the future, Bazel will expand tree artifacts in runfiles, too,
    which causes the sandbox to link each file individually into the
    sandbox directory, instead of symlinking the entire directory. In
    this release, the behavior is not enabled by default yet. Please
    try it out via
    --incompatible_symlinked_sandbox_expands_tree_artifacts_in_runfile
    s_tree and let us know if it causes issues. If everything looks
    good, this behavior will become the default in a following
    release.

This release is a patch release that contains fixes for several serious
regressions that were found after the release of Bazel 0.16.0.

In particular this release resolves the following issues:

 - Bazel crashes with a StackOverflowError on Windows (See bazelbuild#5730)
 - Bazel requires a locally installed JDK and does not fall back
   to the embedded JDK (See bazelbuild#5744)
 - Bazel fails to build for Homebrew on macOS El Capitan (See bazelbuild#5777)
 - A regression in apple_static_library (See bazelbuild#5683)

Please watch our blog for a more detailed release announcement.

Incompatible changes:

  - The $(ANDROID_CPU) Make variable is not available anymore. Use
    $(TARGET_CPU) after an Android configuration transition instead.
  - The $(JAVA_TRANSLATIONS) Make variable is not supported anymore.
  - Skylark structs (using struct()) may no longer have to_json and
    to_proto overridden.
  - The mobile-install --skylark_incremental_res flag is no longer
    available, use the --skylark flag instead.

New features:

  - android_local_test now takes advantage of Robolectric's binary
    resource processing which allows for faster tests.
  - Allow @ in package names.

Important changes:

  - Option --glibc is removed, toolchain selection relies solely on
    --cpu and --compiler options.
  - Build support for enabling cross binary FDO optimization.
  - The --distdir option is no longer experimental. This
      option allows to specify additional directories to look for
      files before trying to fetch them from the network. Files from
      any of the distdirs are only used if a checksum for the file
      is specified and both, the filename and the checksum, match.
  - Java coverage works now with multiple jobs.
  - Flip default value of --experimental_shortened_obj_file_path to
    true, Bazel now generates short object file path by default.
  - New rules for importing Android dependencies:
    `aar_import_external` and `aar_maven_import_external`.
    `aar_import_external` enables specifying external AAR
    dependencies using a list of HTTP URLs for the artifact.
    `aar_maven_import_external` enables specifying external AAR
    dependencies using the artifact coordinate and a list of server
    URLs.
  - The BAZEL_JAVAC_OPTS environment variable allows arguments, e.g.,
    "-J-Xmx2g", may be passed to the javac compiler during bootstrap
    build. This is helpful if your system chooses too small of a max
    heap size for the Java compiler during the bootstrap build.
  - --noexpand_configs_in_place is deprecated.
  - A tool to parse the Bazel execution log.
  - Support for LIPO has been fully removed.
  - Remove support for --discard_actions_after_execution.
  - Add --materialize_param_files flag to write parameter files even
    when actions are executed remotely.
  - Windows default system bazelrc is read from the user's
    ProgramData if present.
  - --[no]allow_undefined_configs no longer exists, passing undefined
    configs is an error.
  - In remote caching we limit the number of open
    TCP connections to 100 by default. The number can be adjusted
    by specifying the --remote_max_connections flag.
