Quintin Siebers commented on JENKINS-9241: ------------------------------------------ When I had this problem, it was because the Apache zip was extracted into {MavenName}/apache-maven-3.0.4, while Hudson checks the {MavenName}/lib folder. The solution is to manually move your extracted maven up one directory. > maven2: java.lang.IllegalArgumentException: /usr/bin/mvn without lib directory > ------------------------------------------------------------------------------ > > Key: JENKINS-9241 > URL: https://issues.jenkins-ci.org/browse/JENKINS-9241 > Project: Jenkins > Issue Type: Bug > Components: maven2 > Affects Versions: current > Environment: Ubuntu 10.10 hudson running inside tomcat6 > Reporter: ssbarnea > > I get the following error when I try to execute a maven task from hudson. > Maven is installed on the OS and I'm able to use it from the command line. > Maven is configured inside Jenkins config but I still get this unclear error. > java.lang.IllegalArgumentException: /usr/bin/mvn without lib directory > at > hudson.maven.MavenEmbedderUtils.buildClassRealm(MavenEmbedderUtils.java:81) > at > hudson.maven.MavenEmbedderUtils.getMavenVersion(MavenEmbedderUtils.java:170) > at hudson.maven.MavenVersionCallable.call(MavenVersionCallable.java:56) > at hudson.maven.MavenVersionCallable.call(MavenVersionCallable.java:40) > at hudson.FilePath.act(FilePath.java:785) > at > hudson.maven.MavenModuleSetBuild$RunnerImpl.doRun(MavenModuleSetBuild.java:568) > at hudson.model.AbstractBuild$AbstractRunner.run(AbstractBuild.java:423) > at hudson.model.Run.run(Run.java:1362) > at hudson.maven.MavenModuleSetBuild.run(MavenModuleSetBuild.java:454) > at hudson.model.ResourceController.execute(ResourceController.java:88) > at hudson.model.Executor.run(Executor.java:145) -- This message is automatically generated by JIRA.
