Title: Message Title

Daniel Carrington created an issue   Jenkins / JENKINS-56688 pipeline-syntax Global Variables params.get doesn't work Issue Type: Bug Assignee: Jesse Glick Components: workflow-job-plugin Created: 2019-03-22 17:36 Environment: jenkins 1.50.2, all workflow plugin versions Priority: Minor Reporter: Daniel Carrington In Pipeline, doing params.get as recommended by Jesse Glick in: https://github.com/jenkinsci/workflow-cps-plugin/commit/7c29a4d24f575e61d80a7aed7b48d6ba5750a5a6 doesn't work because Groovy Map.get(Object, Object) actually tries to modify the map; whereas the params Map is an UnmodifiableMap. When I tried this code, I got the exception: java.lang.UnsupportedOperationException at java.util.Collections$UnmodifiableMap.put(Collections.java:1457) at org.codehaus.groovy.runtime.DefaultGroovyMethods.get(DefaultGroovyMethods.java:7080) I recommend instead Map.getOrDefault, which does not try to modify the Map. Pull request incoming for an update to documentation.
