-----------------------------------------

             Summary: Exclude generated sources / test-sources from default source / test-source directories
                 Key: MCHECKSTYLE-412
                 URL: https://issues.apache.org/jira/browse/MCHECKSTYLE-412
             Project: Maven Checkstyle Plugin
          Issue Type: Improvement
          Components: checkstyle:check, checkstyle:checkstyle
    Affects Versions: 3.1.2
            Reporter: Zhenlei Huang


The default value of parameter `sourceDirectories` is  `${project.compileSourceRoots}`, which includes generated sources. And for `testSourceDirectories` is `${project.testCompileSourceRoots}` which includes generated test sources.

The major usage of checkstyle is to enforce rules on human written codes and docs. The generated ones commonly  come from third-party templates or scripts, and it probably does not meet user defined checkstyle rules.

We can bravely conclude exclude the generated sources / test sources directories and the impact should be trivial.
