-------------------------------------
Summary: Compilation fails due to removed generated-sources after
upgrade from 3.11.0 to 3.12.0+
Key: MCOMPILER-589
URL: https://issues.apache.org/jira/browse/MCOMPILER-589
Project: Maven Compiler Plugin
Issue Type: Bug
Affects Versions: 3.13.0, 3.12.1, 3.12.0
Reporter: Eric Hubert
After upgrading the used maven-compiler-plugin from 3.11.0 to 3.13.0 the class
compilation fails, because generated resources are no longer present in the
generated-sources folder.
The project is setup in a way that during the generate-sources phase a plugin
generates java sources which are stored in the configured generated-sources
folder. Within the same phase these are added to the source using the
build-helper-maven-plugin's add-source goal.
When debugging the maven execution one can verify how the files are generated
and placed in the correct folder. Once the maven-compiler-plugin > 3.11.0 is
executed, the generated sources are deleted before the actual source code is
compiled finally resulting in a compilation error. The issue can be reproduced
with 3.12.1 and 3.12.0 and does not happen with 3.11.0.
I did not yet find the time to debug the plugin, but briefly checked the
release notes and found the ticket MCOMPILER-333 which might be the cause.
