@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.
