How to clone a BitBucket repository with Jenkins

For Jenkins 1.5 or greater( till 1.6)

The error you are getting because in the global configuration of Jenkins, the git path is not correct/or not inserted.

That's why Jenkins is unable to run the git command.

Please go to Manage Jenkins-> Configure System Settings. Check for git section and add correct path.
