Revision history [back]

According to the error messages you are missing some Java packages. Until recently the buildfarm downloaded e.g. diffutils on demand. But as of https://github.com/ros-infrastructure/ros_buildfarm/pull/418 the Jenkins Groovy plugin provides that library already.

Your instructions mention that you are using an older version of Jenkins and therefore likely older plugins. You might want to try using the same version as on the ROS buildfarm (currently Jenkins 2.46.2 and Groovy 2.0).

Please also note that there is an active effort to update the buildfarm_deployment to use Xenial instead of Trusty. That upgrade will also move us from Java 7 to Java 8 which will allow us to upgrade to a newer Jenkins version which require Java 8.
