Build step 'Invoke top-level Maven targets' marked build as failure

This seems to be an issue concerning the maven pathway, but I've setup the maven pathway on my host machine. M2_HOME, M2, and PATH are all correct. I know they are correct because I can run the maven commands from the command line. When I try to invoke maven commands in jenkins though I get the error. So I went into Jenkins->Manage Jenkins->Configure System and I clicked on Maven installations... I checked off on

Install automatically
Version 2.2.1

I clicked save and tried to run my project again with the same error. When I do mvn -version I get 2.2.1 so that should be right. From the Configure System page I have also tried

Name default
MAVEN_HOME /usr/local/apache-maven/apache-maven-2.2.1

Any ideas?

Answer 1

The solution to my question has two parts. First I needed to make sure that after creating the maven Installation setup on the Configure System page, that I specified that same configuration in the build itself. Second Jenkins does not seem to have sufficient privileges on the redhat box I'm running it on. Once I finally got it pointed to the right maven instance I got a lot of unable to create file/folder errors. These permission errors could be the real reason I had so much trouble with maven on this machine. I have not solved these permission errors and will create a new question for them.
