Better error handling for PMDException
---------------------------------------
Key: MPMD-65
URL: http://jira.codehaus.org/browse/MPMD-65
Project: Maven 2.x PMD Plugin
Issue Type: Improvement
Components: PMD
Reporter: Xavier Le Vourch
Attachments: PMDException.patch
PMDException is not caught and this means an exception stack is displayed when
an error occurs, for instance when annotations are used with targetJdk set to
1.4.
With the attached patch, the plugin now displays a single line:
[WARNING] Error while parsing
/home/xlv/dev/pmd/maven/mvn_test/src/main/java/com/brittanysoftware/pmd/test/App.java:
Can't use annotations when running in JDK 1.4 mode!
instead of an exception stack:
[WARNING] Failure executing PMD for:
/home/xlv/dev/pmd/maven/mvn_test/src/main/java/com/brittanysoftware/pmd/test/App.java
