Andrey Utis created MPMD-161:
--------------------------------
Summary: PMD/CPD violation exclusions by class/issue
Key: MPMD-161
URL: https://jira.codehaus.org/browse/MPMD-161
Project: Maven 2.x PMD Plugin
Issue Type: New Feature
Components: CPD, PMD
Reporter: Andrey Utis
Attachments: pmd2.7.1_exclusions2.patch
I work on a system that has a lot of legacy code with a lot of PMD/CPD
violations. Introducing PMD to the build is not an easy option, since the build
would always fail. So the next best thing is to exclude any existing violations
and only fail if a new violation is introduced. Unfortunately, if I have
thousands of violations, PMD doesn't provide a good way to do this. I'd have to
add comments or annotations to all these places to ignore the violation.
We came up with an alternative solution to this. We modified the PMD plugin to
read a properties file that contains a mapping of class name to a list of
excluded violations. If a particular violation is in this file, it does not
cause the build to fail. Similar idea for CPD.
An svn patch is attached (apply to 2.7.1)
(Disclaimer: this is probably not the most elegant piece of code but it works
and it was quick. Feel free to re-factor and make it more in line with the rest
of the plugin code)
