Continue of JENKINS-37647.

I checkout DSL test repo from job-dsl-gradle-example and run tests successfully on my Ubuntu with Jenkins.

But when I changed Jenkins version to 2.19.1 tests fails with error:

Caused by:
10:57:43.638 [DEBUG] [TestEventLogger] javaposse.jobdsl.dsl.DslScriptException: (script, line 72) No signature of method: javaposse.jobdsl.dsl.helpers.triggers.TriggerContext.githubPullRequest() is applicable for argument types: (script$_run_closure2$_closure8$_closure9) values: [script$_run_closure2$_closure8$_closure9@4c560437]

Changing back Jenkins version solved this issue.

Then I try to use

./gradlew rest

to create job without tests - fails again with the same error.

Interesting note: tests runs successfully on my macOS with any Jenkins version. I found same issue: job-dsl-gradle-example/issues/64
