[kltm]

Obtained Jenkinsfile from 9fe164d9aa2ee9cadece2928dbe6a4a30f3c98dc
org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
General error during class generation: Method too large: WorkflowScript.___cps___8459 ()Lcom/cloudbees/groovy/cps/impl/CpsFunction;

groovyjarjarasm.asm.MethodTooLargeException: Method too large: WorkflowScript.___cps___8459 ()Lcom/cloudbees/groovy/cps/impl/CpsFunction;
    at groovyjarjarasm.asm.MethodWriter.computeMethodInfoSize(MethodWriter.java:2087)

I'm guessing this is basically https://github.com/geneontology/pipeline/issues/183
