Hi,
I've installed the beta version of Workflow plugin
(https://github.com/jenkinsci/workflow-plugin)
I created one Workflow job with the following DSL:
def myClosures = [:]
myClosures['Project1'] = {
println "in myClosure of Project1";
run_on_node 'Project1'
}
myClosures['Project2'] = {
println "in myClosure of Project2";
run_on_node 'Project2'
}
print myClosures
parallel(myClosures)
def run_on_node(project) {
echo "in run_on_node() project=${project}"
echo "Getting hostname"
sh 'hostname'
echo "Listing /tmp directory"
sh 'ls -lrt /tmp'
}
When I run the above, it gives below error:
Console Output

Can you explain the usage of parallel() in workflow DSL? Is there any
documentation on the workflow. So far I only found this link:
https://github.com/jenkinsci/workflow-plugin-pipeline-demo/blob/master/flow.groovy
Thanks for your help in advance!
