jenkins-shared-library | Declarative Pipeline - Jenkins | Continuous Deployment library

This job DSL error seems to happen when a function doesn't compile. In this case the function doesn't compile because groovy does this thing where you can call functions without parentheses.

Examples:

This is documented in the DSL documentation of DependencyHander:

https://docs.gradle.org/current/dsl/org.gradle.api.artifacts.dsl.DependencyHandler.html#N16E3D

There are two notations supported for declaring a dependency on an external module. One is a string notation formatted this way:

configurationName "group:name:version:classifier@extension"

The other is a map notation:

configurationName group: group, name: name, version: version, classifier: classifier, ext: extension

And is further documented in the Javadoc:

https://docs.gradle.org/current/javadoc/org/gradle/api/artifacts/DependencyArtifact.html#getExtension--

Returns the extension of this artifact. Often the extension is the same as the type, but sometimes this is not the case. For example for an ivy XML module descriptor, the type is ivy and the extension is xml.

To answer your questions :
Is there a way to add away to add a custom pipeline stage in our jenkinsfile that will run after the shared-library code is run all as part of the same pipeline?
Is it possible to import 2 shared libraries and use both together as part of the same pipeline ?
Yes to both of the question, you can add any number of custom stages in your pipeline and also it can run after the shared-library code is running.
Example of Jenkinsfile and new shared library file as below:

Turns out I was using the JCenter site for fetching the artifactory dependencies. Once I switched to the JFrog site, all worked well.
