Currently I have added:
1. pipeline-build-step 2. workflow-api 3. workflow-basic-steps 4. workflow-cps 5. workflow-job 6. workflow-scm-step 7. workflow-scm-step-api 8. branch-api
Discussion on Jenkins dev mailing list https://groups.google.com/forum/#!topic/jenkinsci-dev/Tc0Vdcmzzio
Fixed by adding test scope of workflow step api.
Pipeline: Declarative dependency is required with
groupId is org.jenkinsci.plugins
artifactId is pipeline-model-definition
version is 2.4
Not adding the dependency to the plugin for now as it causes a lot of dependency management issues.
