Re: java.lang.UnsupportedOperationException in set map with each This is due to IteratorHack in workflow-cps, which is how we're able to do iteration over map entries without serialization errors. You'll need to work around this - say, with something like: Map buildStatus = ['a':'C', 'b':'N', 'c':'R', 'd':'R'] List nextBuildBranches = ['c', 'd'] nextBuildBranches.each { b -> buildStatus.put(b, "C") } println buildStatus
