How do I build on specific commit in Git on Jenkins?

Question

I am trying to build my project from a specific commit, in Jenkins.

I have specified the branch to build and it's building from the HEAD commit.

However I want to build from any specific revision/commit.

I tried passing a GIT_COMMIT value as a parameter but it's picking up the HEAD commit only.

I also tried using svn type thing like https://svn-url@$REVISION where REVISION is parameter passed in build.

For git it doesn't recognize ssh://git-url@REVISION.

1. Jenkins Git plugin should be
2. Copy your commit hash and paste it into "Branch Specifier"

Then Run "Build now"

Answer 2

Well I think instead of hacking the build config to point to a specific commit hash, it would be better to just create a new branch, that points to the commit you want to build. If you have a correctly configured Multibranch Pipeline Build, Jenkins should discover and build your commit/branch automatically.

Alternatively you could also use a tag instead of a branch. But in this case you need to add the "Discover tags" Behaviour to your Branch Source Config.
