Hi Erik, I personally wouldn’t recommend putting MAVEN_HOME in a profile, rather it is better to let Jenkins managed this by specifying the version of maven to use.
You can configure this in the Jenkins main config (and then override per slave if needs be.) See http://my.safaribooksonline.com/book/software-engineering-and-development/ide/9781449311155/configuring-your-jenkins-server/sect-configuration-build-tools for more details. BTW – is this with the “m2release plugin” on a maven type job or with the “release plugin” on a freestyle job? /James From: jenkinsci-users@googlegroups.com [mailto:jenkinsci-users@googlegroups.com] On Behalf Of Erik Sent: 17 September 2012 08:44 To: jenkinsci-users@googlegroups.com Subject: Re: Problem with MAVEN_HOME in a build I get the same exception in Jenkins v. 1.477 and maven 2.2.1 Everything works fine, except for the release.

MAVEN_HOME variable is correctly set during the first build (and any 'normals' builds), but when we launch a release and the build arrive to the command 'mvn .. release:clean release:prepare release:perform' to launch the Maven3 release, it seems that the MAVEN_HOME variable is not set correctly and the build crashs with this error : class not found: org.codehaus.classworlds.Launcher - org.codehaus.classworlds.Launcher We have also Maven2.2.1 and Maven3.0.3 installed on the master (AIX) which build this job. In .profile file, M2_HOME is by default set to Maven2.2.1. The problem is appeared since we have updated Jenkins with version 1.478. The same job worked correctly before the update (last release has been built just before our update of Jenkins and the mvn command worked correctly). Is this a bug ? Does I create a ticket in Jira ? Thanks in advance from any help !
