I would like to use the same Ruleset in my IDE (Eclipse) that my Sonar profile.
I got the PMD XML ruleset from the Sonar Permalinks and would like to import it into my PMD Eclipse Plugin but when i try to do it, the "OK" button is desactivated ...
Can someone help me ?
The problem could be that Sonar is exporting your ruleset for v4.x format and your Eclipse plugin expects them in v5.x format.
Try changing your rules from:
<rule ref="rulesets/basic.xml/UnusedNullCheckInEquals">
<priority>3</priority>
</rule>
to
<rule ref="rulesets/java/basic.xml/UnusedNullCheckInEquals">
<priority>3</priority>
</rule>
Please note the ref attribute. A simple find and replace all will work out fine for you.
