Excluding classes in Maven Checkstyle plugin reports

Question

I have a Maven 2 project and I want to configure my Checkstyle report plugin so that only some of my classes are analysed. I have found the maven.checkstyle.excludes<

Answer 1

If, like me, you arrived here searching for a way to exclude generated sources from checkstyle, do this:

  org.apache.maven.plugins
  maven-checkstyle-plugin
  2.15
  
    ${project.build.sourceDirectory}
  

By default, the checkstyle:checkstyle goal of the checkstyle plugin uses ${project.compileSourceRoots}, which apparently includes generated source directories.

If you change it to ${project.build.sourceDirectory}, it will use only the source directory, not any generated source directories.

Note that while is deprecated, the alternative, , does not appear to work.
