Where does Jenkins store the project source - maven

Question

I have a Jenkins job that uses a script to build my project. On the following line, the script fails mvn -e -X -Dgit='$git' release:prepare.
Because I want to search for the cause of this, I want to go to the Jenkins server and run mvn -e -X -Dgit='$git' release:prepare from the command line, to see if it works.
Does Jenkins store the projects' source code somewhere, such that I can go to that folder and call Maven?
If yes, then where?

Answer 1

Yes, It Stores the project files for the job by default at
/var/lib/jenkins/workspace/{your-job-name}
This is where jenkins suppose the project files to be present or it pulls it from a source before start working/building from it.

Answer 2

Quote from Andrew M.:
"Hudson/Jenkins doesn't quite work that way. It stores configurations and job information in /var/lib/jenkins by default (if you're using the .deb package). If you want to setup persistence for a specific application, that's something you'll want to handle yourself - Hudson is a continuous integration server, not a test framework.
Check out the Wiki article on Continuous Integration for an overview of what to expect."

Answer 3

This worked for me:
/var/jenkins/workspace/JobNameExample
but, if your build machine (node) is a different than the one where Jenkins is running (manager), You need specify it:
/var/jenkins/workspace/JobNameExample/label/NodeName
Where you can define label too:

Answer 4

jenkins stores its workspace files currently in /var/jenkins_home/workspace/project_name
I am running from docker though!
