How to prevent certain Jenkins jobs from running simultaneously?

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.

That's an old question, but the topic can still be relevant, especially when running application tests on Jenkins.

The Lockable Resources Plugin allows you to define lockable resources that can be used by builds. If your build requires an resource, it takes the lock. If a second build requires the same resource (which then is already locked), it will be queued for the resource to be free.

Although the docs use computers or printers as examples for lockable resources, the database example from above should work as well.

In opposite to the Locks and Latches Plugin mentioned in answers from 2012, this package seems to be currently maintained (currently ~2016).

The Locks and Latches plugin here should help.

This question is probably a dupe of How do I ensure that only one of a certain category of job runs at once in Hudson?
