             Is there a workaround available so that I can have syntax highlighting in IntelliJ IDEA?

            I tried this:

            method(name: 'parallel', type: 'Object', params: [name: 'steps', type: 'Map'], doc: 'Parallel steps')

            …but that doesn't work. I may need to specify a different type (but which one?)

             I added the following lines to the GDSL and it seems to be working, using Intellij IDEA (2017.2.5):

            method(name: 'parallel', type: 'Object', params: [steps: 'Map'], doc: 'Execute in parallel')
method(name: 'parallel', type: 'Object', params: [steps: 'Map', failFast: 'boolean'], doc: 'Execute in parallel')

             

            Another workaround, is to just disable the check by adding the following comment above each call to parallel:

            //noinspection GroovyAssignabilityCheck

            But this is really just ignoring the issue, and unhelpful for autocomplete / syntax highlighting.

            I filed a PR to fix the GDSL issue here. The snippet generator and automatically generated documentation would not be affected by that PR.

            Ok, the GDSL issues should be fixed in Pipeline: Groovy Plugin version 2.73. The documentation issues and error when "generate snippet" is clicked still exist, and I'm not sure of a good way to fix them without more special casing for the parallel step. I'm going to move this back to open.
