Thanks for the suggestion. I will have to do so if I couldn't figure out a fix.
I intend to run it on the Jenkins master for 2 reasons. 1. The Jenkins master has no static working node. Each build task will get a dynamically provisioned worker node. 2. The task which uses the library is very brief. It takes less than 3 seconds when it was working. It feels an overkill to get a worker node.
