Accelerated-build-now-plugin 1.0.1 is incompatible with Pipeline

XMLWordPrintable

      We just upgraded to 2.129. Our jenkins is configured to start nodes as needed; release nodes as upon idle; and run a job on master which turns nodes off if they aren't in use.

      We had the accelerated-build-now-plugin (version 1.0.1) plugin enabled.

      When our normal or pipeline jobs start, they try to pick any node other than master. Jenkins starts the node, it appears in the list of available nodes, but Jenkins doesn't manage to start a build on the node:

      Instead, the jobs sit waiting, and eventually the computers being idle are released by jenkins and then reaped by the job on master.

      Disabling this plugin results in our system working as it used to work.
