> Maven 3 support in maven-plugin
> Key: HUDSON-4988
> URL: http://issues.hudson-ci.org/browse/HUDSON-4988 > Project: Hudson
> Issue Type: New Feature
> Components: maven2
> Reporter: zlosch
> Assignee: olamy
> Attachments: consoleText-maven3-site-build.zip, hudson-m3-tycho-debug-2.txt, hudson-m3-tycho-debug.log
> Hudson maven-plugin doesn't work with Maven 3 on Linux. On Linux Hudson builds its own Java command line and does some additional magic to launch Maven. On Windows it works fine because mvn.bat is used instead.
> The mechanism on Linux fails for two reasons:
> 1. classworlds-*.jar was upgraded to plexus-classworlds-2.2.2 with Maven 3, so the classpath is wrong.
> 2. plexus-classworlds-2.2.2 is not fully backward compatible. After renaming the jar to classworlds-2.2.2.jar the error is:
> $ /opt/java/x86_64/jdk1.6.0_16/bin/java -Xmx768m -XX:MaxPermSize=256m -cp /home/hudson/plugins/maven-plugin/WEB-INF/lib/maven-agent-1.335.jar:/opt/maven/3.0-alpha-5/boot/classworlds-2.2.2.jar hudson.maven.agent.Main /opt/maven/3.0-alpha-5 /usr/share/tomcat5/webapps/hudson/WEB-INF/lib/remoting-1.335.jar /home/hudson/plugins/maven-plugin/WEB-INF/lib/maven-interceptor-1.335.jar 32917

> ERROR: Failed to launch Maven. Exit code = 1
> Skipping sonar analysis due to bad build status FAILURE
> Finished: FAILURE
> Reason for the above error is that getWorld() returns a different type in 2.2.2 which isn't assignable to the type returned in 1.x.
> A general question: Why does Hudson use different mechanisms for launching Maven on Windows and Linux?
> Tested with 1.335
