Groovy .each only iterates one time

Question

The script is not iterating through all the values of the \'modules\' array.

class Module {
    public String name =         


        

Answer 1

The workaround is to simply use an old school for loop (code below). Also, NonCPS is another workaround. There is an open issue for this matter. See here: https://issues.jenkins-ci.org/browse/JENKINS-26481

Update, Oct 24th, 2016

/** * Dumps environment varibles to the log, using an old school for loop. */

import com.cloudbees.groovy.cps.NonCPS

def version = '1.0'

@NonCPS
def dumpEnvVars() {
  def str = "Dumping build environment variables...\n"
  for (Map.Entry<String, String> entry : currentBuild.build().environment) {
    str += "    ${entry.key} = ${entry.value}\n"
  }
  echo str
}

return this;

Answer 2

The messages "Running: Print Message" and "Running: End of Workflow" indicate that you are using the new workflow plugin: https://wiki.jenkins-ci.org/display/JENKINS/Workflow+Plugin. This plugin currently has a bug causing at least some Groovy iterations involving a closure to be aborted after one iteration: https://issues.jenkins-ci.org/browse/JENKINS-26481

Answer 3

As of yesterday, the new Pipeline plugin was delivered in version 2.0 and correct this problem.

.each closures now work, but .collect still only iterate once.
