mvn package fails due to JavaDocs picking up broken source files #2176

Closed msmuenchen closed 5 months ago

msmuenchen commented 5 months ago

Under Maven 3.9.6, attempting to build the project errors out.

The reason is a bunch of files that are excluded in the maven-compiler-plugin config, but not in Javadoc.

Pull request coming in a minute.

Those "errors" don't fail the build, you can ignore them

Thanks for the fix!
