workflow plugin error

[kptishere]

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!

Hi,

at first glance that might be as you are not using a node/workspace and the shell step requires one.
