Cannot run program "mvn" error=2, No such file or directory

Question

I'm doing a build on my Ubuntu 14.04 LTS but I'm getting the following:

I'm assuming that this caused by some linux security feature that stops the /var/lib/jenkins/workspace/videovixx from being created without the correct permissions which I might not have. Is this the problem and how do I solve it?

Answer 1

There are multiple things here.

You either didn't select Maven version in Job configuration. Or you didn't configure Jenkins to install a Maven version. Or you expected to use locally installed Maven on the Slave, but it's not configured for jenkins user.

Since I don't know what you've configured (or didn't configure) and what you expected to use, I can't answer directly, but I can explain how it works.

If you want to use locally installed Maven on master/slave

• You must have Maven locally installed
• You must be able to launch it with jenkins user
  1. Execute sudo jenkins, and then execute mvn on your Slave to verify that jenkins user can run mvn
  2. If that fails, you need to properly install/configure Maven
• In Job configuration, for Maven Version, you must select Default. This is the setting that uses the version that's installed locally on the node

If you want to have Jenkins install Maven for you

• You must go to Jenkins Global Tool Configuration, and configure a Maven version with automatic installer (from the web).
• In Job configuration, for Maven Version, you must select that particular version that you've just configured.
