I got this error when updating dependencies in my project without regenerating the resource-config.json:

After some digging in the code referenced in the stacktrace I found out, that it might have to do with my resource-config.json being outdated and containing a class name which is not on the classpath anymore. However, this shouldn't make the build fail but rather a warning should be printed.

The corresponding code should be here. A check for bundleClass being null should probably be added.

Can you please confirm if the error persists if you generate the config files again after the updating the dependencies?
