ERROR: failed to start build
org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
WorkflowScript: 2: Ambiguous _expression_ could be either a parameterless closure _expression_ or an isolated open code block;
solution: Add an explicit closure parameter list, e.g. {it -> ...}, or force it to be treated as an open block by giving it a label, e.g. L:{...} @ line 2, column 1.
