Sorry for a time without new post – but I have finished now my work on integrating last PMD version 4.3 into JDeveloper.
This is available now for JDeveloper 10.1.3.x, 220.127.116.11 and 11.1.2.x. There is no new functionality, as the most work intensive part was the rewriting for 11.1.2.x. There has changed a lot of JDeveloper api functionality. Additional I tried to solve a class loader conflict in JDeveloper 11.1.1.x with the delivered libraries from PMD 4.3, but I was not succesful. Fortunatly Oracle JDeveloper product management solved this conflict in 18.104.22.168, so I can deliver at least the extension for this JDeveloper version.
Please give it a try, you can download it via the standard update center “Open Source and Partners Extensions” in JDveloper itself or directly from the PMD SourceForge.net Project Page.
