Using a shared library class from a custom step with Jenkins pipeline shared libraries

I am setting up a shared library for Jenkins pipelines and am trying to figure out how to import a class in the shared library into a custom step that I am writing.

Here's what the directory structure looks like:

src
--jenny
----util
------Versioning.groovy
vars
--calculateVersion.groovy

The Versioning.groovy file defines some static helper methods that do some stuff.

package jenny.util
class Versioner implements Serializable {
    static bool checkForValidVersion(version) {
        return true
    }
}

I would like to call this method from the calculateVersion.groovy something like this:

def call(version) {
    return jenny.util.Versioner.checkForValidVersion(version)
}

So that my declarative pipeline can call: def valid = calculateVersion "1.0.0"

But I receive this error No such property: jenny for class: calculateReleaseVersions

Is it possible to reference the classes in the shared library from files in the vars to define custom steps and how is this done?

Yes it is possible. At least for us:

Just like in plain java (or groovy) we put an import statement into the groovy script in vars. In your case that would be something like:

import jenny.util.Versioner

def call(version) {
    return Versioner.checkForValidVersion(version)
}

Another thing I just found: It looks like the file name of the class Versioner doesn't match the class name: Versioning.groovy. Could that be the issue?

If that doesn't work you propably want to upgrade your pipeline plugin version(s).
