Question

I have a couple of jobs that use a shared resource (database), which sometimes can cause builds to fail in the (rare) event that the jobs happen to get triggered simultaneously.

Given jobs A through E, for example, is there any way to specify that A and C should never be run concurrently?

Other than the aforementioned resource, the builds are independent of each other (not e.g. in a upstream/downstream relation).

A “brute-force” way would be limiting number of executors to one, but that obviously is less than ideal if most jobs could well be executed concurrently and there’s no lack of computing resources on the build server.

Answer 1

There are currently 2 ways of doing this:

• Use the Throttle Concurrent Builds plugin.
• Set up those jobs to run on a slave having only 1 executor.
