MultiBranch Mercurial JenkinsFile

This is just a “victory dance” sort of post about setting up a multi-branch build, for a Mercurial project, from a JenkinsFile. When I first tried to do this sthing, I recieved a message reading; ERROR: No configured Mercurial installation which was annoying.

I hadn’t needed to setup Mercurial before, why did I need to now?

Turns out, the workaround/worksforme from here this bug solves the problem by defining the default Mercuiral setup as … the … default?

Step 0; Setup SSH Keys

I don’t know if this is essential, or, what “worksforme” but … I have the Jenkins user using an SSH key with access to my server.

No credentials are stored in Jenkins.

This may or may not be practical; sorry.

Step 1; Define your Mercurial installation

Open Jenkins, Manage Jenkins > Global Tool Configuration / Mercurial / Mercurial installations...

On my Docker container, these settings worked snazzy.

merc-setup

Step 2; Project Setup

Now, you need to add a “Branch Source” to your Multi-Branch Pipeline which uses this Mercuial Installation. The image below illustrates the settings that I used;

merc-setup

Q’apala?

That should do it. The next time your project indexes it should be able to scan your repository for branch heads.
