Feature Request: Provide ability to define exclude pattern about eclipse-pmd HOT 4 CLOSED

You can also do that in your ruleset file so it can be used by any tools, not just Eclipse (ex. maven) :

<ruleset>
  <description>MyPMDConfig</description>
  <exclude-pattern>.*target/.*</exclude-pattern>
  <exclude-pattern>.*src/main/webapp/.*</exclude-pattern>
...
</ruleset>

Yes I know, however I have a ruleset file referenced via URL which is used by multiple projects (and therefore no exclude pattern are defined in this ruleset). If I configure a second, project local, ruleset file with exclude pattern, they are not applied to the rules from the remote ruleset.

I see your point, but if you use maven, the rules will be applied and the checks and reports will contains validations on your generated sources.

Also, I think it is not a bad idea to put this exclude pattern in your remote ruleset. It seems to me that I would like to apply this exclude to any of my projects having generated sources...

That said, I'm not the eclipse-pmd developer, only a user ;)

One of the main goals of eclipse-pmd is to make it easy to let a development team work with the same PMD rule set so a developer can fix the code issues right away and there won't be any PMD violations any more when the code is committed and pushed to the build server. Allowing to define exclusion patterns outside the PMD rule set file would work against this goal. Therefore I won't add exclusion patterns to the .eclipse-pmd file.

However, your problem is a special case: you do not want to check your generated code. This is understandable and eclipse-pmd already supports this. Usually a source folder containing generated code has the "derived" flag set by the generator that creates the code. eclipse-pmd already checks this flag and analyses the code only if it is not set. It seems like your generator did not set this flag. The flag can be set manually by ticking the respective check box in the properties of the folder.

You have to disable and enable eclipse-pmd after setting the flag as it does not seem to automatically pick up the change.

Let me know if that solves your problem.
