Jenkins executing maven from incorrect path

Question

This happens for both: maven projects, and freestyle projects, when maven target is envoked, it tries to execute mvn using absolute path.

[MY-Job] $ tools/Maven/Jenkins_Private_Maven/bin/mvn -f cc/pom.xml -Ddeploy_env=xxx.dev.prv   -Dbranch=dev -D-Dsmdist.target=/opt/builds -U clean test -DtestGroups=unit,delegate -Do verride:server=xxx.dev.prv
FATAL: command execution failed 
java.io.IOException: Cannot run program "tools/Maven/Jenkins_Private_Maven/bin/mvn" (in    directory "workspace/MY-Job"): java.io.IOException: error=2, No such file or directory

I can see that mvn is installed at user's home :

/home/jenkins/tools/Maven/Jenkins_Private_Maven/bin/mvn  

but it's trying to run it from the workspace:

/home/jenkins/workspace/MY-Job/tools/Maven/Jenkins_Private_Maven/bin/mvn

Answer 1

1. Add the default maven installation under (Jenkins -> configuration)

2. Goto the failing job and make sure you choose the default maven installation from dropdown

3. Run the job. Success!
