Jenkins unable to run Maven

Question

I followed this tutorial to setting up Jenkins with GIT and Maven (with slight changes because i'm using Linux CenOS).

I'm trying to test my setup on a Demo Maven project from GitHub

Jenkins throws an exception when trying to execute Maven. So I tried to git-clone the project and run Maven manually and it works fine.

So the problem is with Jenkins running Maven. I tried searching google for the problem but couldn't find any useful information.

My current suspicions are:

1. Maybe Jenkins doesn't use the correct classpath for executing Maven. This could be due to lack of permission to read files, since Jenkins has it's own user on linux (named jenkins).
2. Maybe Maven isn't installed correctly. I installed it manually, rather than letting Jenkins install it for me, since I need this setup to be working offline.

Here is the console output from Jenkins:

Ideas anyone? Thanks.

Answer 1

Apparently the problem was that I installed the newest alpha version of Maven, which is unstable. With the latest stable version - 3.0.5 - everything works fine.

Answer 2

Here it is:

If you're not letting Jenkins install Maven, then you need to configure the location of the Maven installation it should use.
