##  A build script                                                          ##

##  Note that in the past, this script took the following responsibilities  ##
##  that are now handled by ./mvnw (a.k.a. Maven Wrapper) or Maven itself:  ##
##                                                                          ##
##  * Download and install a specific version of Maven                      ##
##  * Set Maven options via MAVEN_OPTS environment variable - these can     ##
##    now be set in .mvn/jvm.config and .mvn/maven.config                   ##
##                                                                          ##
##  The only task left in this script is settting a sufficient limit for    ##
##  the open files (a.k.a. ulimit -n). If this is not important to you,     ##
##  feel free to use ./mvnw directly                                        ##
##                                                                          ##
