Load Jenkins shared library from same branch as current pipeline source

Background

I have complex build system which is working and uses shared library. Pipelines code is stored in same git repository as shared library. Both sources are on master branch.

Problem

Now I do larger refactoring to improve build and test process. So I'm working on feature branch and I configured respective Jenkins job to test it.

Since I introduce changes also to shared library one thing is annoying: to import library I have to import this library this way:

@Library('my_library@feature') _

So to merge this changes to master I have to update code.

Is there a way to access branch (or other kind of reference) which current pipeline code was checkout? So when I merge branches shared library follows to without altering code.

I was thinking something like this:

@Library("my_library@${PIPELINE_SOURCE_REF}") _

I search documentation and internet and didn't found anything like this.

Or is there an alternative solution?

On some none public repository I've found something like this in front of the pipeline.

def pipelineBranch = scm.branches[0].name
library("someLibrary@${pipelineBranch}")

Didn't test it yet, but it seams reasonable. scm.branches[0].name should contain name of branch used to checkout pipeline code.

If it is enough for you to use a parameter for the library branch, it is possible to do so, check out the shared libraries documentation

You would need to change:

@Library('my_library@feature') _

to

library("my_library@${params['BRANCH']}")

This should load the global vars.

If you need to instantiate some class, it is possible to do something like:

def someClass = library("my_library@${params['BRANCH']}").com.mypackage.SomeClass.new(this)

It has some limitations mentioned in the docs, depends on how your library looks like
