  • The Git Plugin is unable to authenticate with RHEL6


  • git < 1.7.9

  • Red Hat Enterprise Linux

  • CloudBees Jenkins Enterprise

  • Git Plugin


Ultimately, you need to be running with git => 1.7.9.

Red Hat makes a version of git > 1.7.9 available through its Developer Toolset. The solution is to install RHT developer toolset, which includes git 1.8.x:

Root Cause

RHEL 6.x includes git client version 1.7.1 by default. This version of git was shipped in April, 2010. The Jenkins git-plugin requires at least git version 1.7.9 but preferably git 1.8.x or higher. One issue with this older version of git is that it is not compatible with Jenkins’s git-plugin and the credentials-api.
