Hi Josef, If you put 5.2 then you'll get version 5.2 even if you have version 6.0M1 in your local repo. To debug this, you could use "mvn help:effective-pom" and then version used.

Since the project is not Java7 yet, the build fails. I tried to set the version in square brackets [${commons.version}] to require a hard version of the extension, but this shows no effect. <extension> <groupId>org.xwiki.commons</groupId> <artifactId>xwiki-commons-tool-xar-handlers</artifactId> <version>${commons.version}</version> </extension> Is there any solution or do I have to upgrade the project to Java7?

Vincent, the XAR plugin shouldn't care about the Java version no? I  think Josef has problems with the Enforcer plugin.    Hope this helps,  Marius    On Wed, Mar 26, 2014 at 1:24 PM,
