If you navigate to the "Manage Jenkins" page you can set the location of
the .m2 directory in the "Maven Project Configuration" section.

<yourjenkinsurl>/configure

You can set it to be "Local to executor" or "Local to workspace". I
suspect that you want "Local to workspace".

Hi,

thanks for your reply but that didn't solved the problem. :(

This option only changes the location of the local repository. The path to the .m2 directory does not change by using this option.

A build fails with this error message:

ERROR: Failed to create /not/existing/user/dir/.m2

I've looked at the source code of the maven-plugin and saw the path is hard coded to the property "user.home". Is there any way to set the user.home property in a Maven job?

Regards

Michael

Hi,

I already tried that using the MAVEN_OPTS configuration field. But Maven still uses the old home directory.

[Nord, James]

Jenkins did (does) use the local users repo when it is parsing the POM files (before the invocation of maven on the executor)

 

If you switch to the freestyle job this should work – but you will loose all of the goodness that comes with the Maven2 type job.

 

But – as you’re administrators expect this to be set per web-app in the app server why don’t you ask them to configure it for you on the app server?

OK, that would be the best option. But I heard you can only change the property for all webapps using the CATALINA_OPTS environment variable.

Is there a way to just change it for one webapp?

They said me, they are "just" administrators but have no knowledge about Java... So I also have to search for the solution to set the property in Tomcat.

I'm having this issue, too.  Since we already set a JENKINS_HOME, shouldn't that be used, instead of whatever user.home is set to?  For me, Jenkins is running under Tomcat from Ubuntu's apt repository, so it is running as the tomcat7 user which has a home of /usr/share/tomcat7, which isn't writable by the tomcat7 user.  Looking at JIRA and googling around, it doesn't appear that anyone else thinks this is a problem, so maybe I am not understanding something.  

I realize that ~/.m2 is the standard, but I can't think of any reason why this standard should be adhered to so strictly that no customization is allowed, even for non-recommended cases.
