Re: GString not flattened to String by DSL inside a map In Groovy, you have to escape symbols for map literals keys: [(requiredFile): 'xxx'] http://groovy-lang.org/groovy-dev-kit.html#_map_literals : Map keys are strings by default: [a:1] is equivalent to ['a':1]. This can be confusing if you define a variable named a and that you want the value of a to be the key in your map. If this is the case, then you must escape the key by adding parenthesis That means the workaround of using a GString as a key should not be needed Add Comment

Re: GString not flattened to String by DSL inside a map

The above does not work and still generates the exception: def file = "name-$ {env.BUILD_NUMBER} " [(file) : "."] still results in java.lang.ClassCastException: org.codehaus.groovy.runtime.GStringImpl cannot be cast to java.lang.String at org.jenkinsci.plugins.workflow.steps.ArtifactUnarchiverStepExecution.run(ArtifactUnarchiverStepExecution.java:44) at org.jenkinsci.plugins.workflow.steps.ArtifactUnarchiverStepExecution.run(ArtifactUnarchiverStepExecution.java:20) at org.jenkinsci.plugins.workflow.steps.AbstractSynchronousNonBlockingStepExecution$1$1.call(AbstractSynchronousNonBlockingStepExecution.java:49) at hudson.security.ACL.impersonate(ACL.java:213) at org.jenkinsci.plugins.workflow.steps.AbstractSynchronousNonBlockingStepExecution$1.run(AbstractSynchronousNonBlockingStepExecution.java:47) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:511) at java.util.concurrent.FutureTask.run(FutureTask.java:266) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) at java.lang.Thread.run(Thread.java:745)

Re: GString not flattened to String by DSL inside a map

I found this thread because I was running into the exact same error. I was able to get it working by adding .toString() along with the () in the mapping. So in this case it would be: def file = "name-$ {env.BUILD_NUMBER} ".toString() [(file) : "."] HTH
