fabric8-pipeline-library | Fabric8 Pipeline for Jenkins | Continuous Deployment library

I am trying to writing a Jenkins Shared Library for my CI process. I'd like to reference a class that is in the \src folder inside a global function defined in the \vars folder, since it would allow me to put most of the logic in classes instead of in the global functions. I am following the repository structure documented on the official Jenkins documentation: Jenkins Shared Library structure

Here's a simplified example of what I have:

/src/com/example/SrcClass.groovy
