Advanced clone behavior caused all branches to build

[Sverre Moe]

Adding Branch Source "Advanced clone behaviors" caused Jenkins to initiate build of ALL my branches.

All I wanted was to make sure the git tags where fetched during checkout.

Takeover for application » master by source #1 from source that no longer exists
Branch reopened: master (ae0617dc2ceea28577b4c73356f705f2d597ae6c)

The branch was never "closed".

After saving the project it performed a Multibranch Pipeline scan. Then it started building almost 300 branches.

It took forever to cancel all those builds.

I ultimately had to remove the advanced clone behavior. Then just add a simple sh "git fetch  --tags --quiet" to my pipeline script.

Desperately need an Kill All jobs in Jenkins. Having 2-300 jobs suddenly triggered is a nightmare.

And because Jenkins will NOT kill the job immediately I need to click like a maniac several times on cancel.

When I mean kill, I mean kill, the consequences be damned.

I am not sure if it was the advanced clone behavior that causes this.

Another project that got triggered by notifyCommit URL just started to build ALL branches.

The only other change I have done was to add Discover Tags.

Perhaps it is the way I did it?

I deleted the existing Branch Source and created a new one.

Perhaps that is Why it is rebuilding all branches?

However, if I scan again, it will trigger all branches again. Every time.

        gitSCMSource.setTraits(traits)

        sources.add(branchSource)
    }
}

It seems more evident now that the reason for all branches gotten triggered was that I scratched the Branch Source configuration and created a new one.

After I let all the branches build (fail and succeed) then scanning again would not trigger a second run.
