You are; for Jenkins to do what it does (in this case, report on the code changes involved in a build), it must know what code is being checked out and built. It accomplishes that by having its SCM provider(s) do the checkout *before* the job starts running user-provided steps. If the user-provided steps change the code that is used to do the build, there is no practical way for Jenkins to be made aware of that.
----- Original Message ----- From: [email protected] To: [email protected] At: Jun 27 2013 13:06:34 It seems unusual to require two (nearly) identical Jenkins jobs to support this (only difference is the branch that you are building on). We have a lot of Jenkins jobs and if we can’t come up with a solution, we double the number of jobs in the system. That is a lot of “job clutter” for no real good reason. I have to believe that Jenkins has to have some way around this. Other build systems support this type of functionality and Jenkins is pretty flexible. Maybe I am just in denial… From: [email protected] [mailto:[email protected]] On Behalf Of nicolas de loof Sent: Thursday, June 27, 2013 12:54 PM To: [email protected] Subject: Re: Modifying Git branch dynamically ok, I guess you have two use cases here that require distinct jobs.

CI builds are initiated when developers push a commit to our Stash server, in which case it makes an HTTP call to the Jenkins server with the Stash URL. For jobs that match the URL, Jenkins checks the branch specifier to determine whether a code change was made for that branch; and if so, then executes the job. If the branch specifier is “$OVERRIDE_BRANCH”, then the CI build is not executed (even though it should be executed. So, long story short, in order to get CI builds to work, I had to set the branch specifier to or CI branch (“develop”).

A build input parameter “OVERRIDE_BRANCH” allows the user to specify an alternative Git branch. A Groovy script build step looks to see if $OVERRIDE_BRANCH has been specified, and if so, it checks out that branch for the build. Problem When I run a build, it runs successfully. However, when I navigate to the Jenkins build output page, it lists the Git code Changes for the develop branch. This makes sense, because Jenkins has no way of knowing that our Groovy script changed the branch. Question Is there a way in Jenkins to tell it that the Git branch (and hence corresponding Git revision) has changed? NOTE I know one “solution” would be to change the Git default branch specifier to the $OVERRIDE_BRANCH parameter; however, that is not desirable for some other reasons. Long story… Thanks for reading this and any help. Bob *** *** *** This message contains information which may be confidential and privileged.
