How to block jenkins build till certain pipeline stage is finished

Question

I have two builds:

• Build 1
• Pipeline Build 2 with stages: A -> B -> C

Is it possible to block Build 1 till stage B is finished?

Standard blocking plugin checks only names of other jobs.

Answer 1

An easy way to do it is to schedule both Build 1 and stages A and B on some node with a unique label. This way, if the Build 2 is running and already using that node, Build 1 will be waiting in the queue on the node.

Another option to consider is using Lockable Resources plugin.
