Subject [jira] Created: (MPMD-60) @SuppressWarnings causes maven PMD plugin to fail on building report

@SuppressWarnings causes maven PMD plugin to fail on building report
--------------------------------------------------------------------

                 Key: MPMD-60
                 URL: http://jira.codehaus.org/browse/MPMD-60
             Project: Maven 2.x PMD Plugin
          Issue Type: Bug
          Components: PMD
    Affects Versions: 2.2
         Environment: Windows XP, Java 6, Maven 2.0.6, PMD-3.9 plugin
            Reporter: Pieter Iserbyt


When running mvn pmd:pmd, the plugin crashes at the time it tries to create the report.

This seems to happen when violations are present that are suppressed by a @SuppressWarnings("PMD")
or @SuppressWarnings("PMD.a_warning_name") annotation.

Also, java keywords are not recognized by PMD, e.g. for @SuppressWarnings("unused"), violations
are logged anyway.

D:\trunk\quality>mvn pmd:check -e
+ Error stacktraces are turned on.
