强制Jenkins重建MultiBranch Pipeline项目中的所有分支

Question

I would like Jenkins to rebuild all existing git repository branches after scheduled branch indexing even if there were no changes since last build but right now I can do that only manually.

Checking branch MyBranch
Met criteria
No changes detected in MyBranch (still at db2c95ede39116529fec42a5fcdd54f0a2dd93d1)

Is there any way to trigger a scheduled build if it detects no changes?

Jenkins 2.7.4

I had the same need - I wanted a clean and a forced build every weekend. I used the Parameterized Trigger Plugin , created a new job:

I scheduled it the way I wanted, and added steps to trigger all the branches in the main job:

It is not very flexible, as you have to modify the builds to trigger each time you add a branch to your pipeline; it also defeats the "CI as code" and zero configuration principle; but if that's not something you do everyday, and have a procedure your developpers follow when they change something on Jenkins, you can write it down there and be just fine.
