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

             Summary: checkstyle:check only supports xml output format, but the docs say it supports plain as well
                 Key: MCHECKSTYLE-337
                 URL: https://issues.apache.org/jira/browse/MCHECKSTYLE-337
             Project: Maven Checkstyle Plugin
          Issue Type: Bug
          Components: checkstyle:check
    Affects Versions: 2.17
            Reporter: Stig Rohde Døssing
            Priority: Minor


The documentation for the check goal at https://maven.apache.org/plugins/maven-checkstyle-plugin/check-mojo.html#outputFileFormat mentions "plain" as a valid option for file output. This is not true, the mojo only supports XML.

I'd prefer added support for plain output, but the docs should be fixed if that is not possible.

Taking a look at the code, it looks like the only reason plain isn't supported is because the check mojo needs to parse the output file to figure out if there were style violations. An option would be counting errors with the AuditListener instead, but this would break support for skipExec. An alternative would be to output an extra XML result file if the output format isn't XML.

I'd be happy to implement either solution.
