>                 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
>            Assignee: Michael Osipov
>            Priority: Minor
>
> 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 they probably do not meet user defined checkstyle rules.
> We can bravely conclude exclude the generated sources / test sources directories and the impact should be trivial, although it is a breaking change.
