Interesting, thanks!
We use jenkins-cli, more or less like this:
cat script.groovy | java -jar ./jenkins-cli.jar -ssh -user userID -i
key_rsa -s "${server}" groovy = >> output.xml
Probably based on an old approach. I'll switch it with curl...

Indeed, the data is there, it seems that an *@Exported* annotation would do
it:
https://github.com/jenkinsci/jenkins/blob/master/core/src/main/java/hudson/model/Queue.java#L2155
I'm not sure about the implications though.
Anyway, I would like to get the Label because I need to know in advance
whether I should connect a node to that Master or not. But I forgot the
fact that the Label can be a regular expression, and that kind of kills my
purpose because I would then need to resolve the expression also in
advance. And replicating the Jenkins mechanism for that wouldn't be so wise
in the long term.
I tried to use the method
*Jenkins.instance.queue.countBuildableItemsFor(Label)* to ask Jenkins
itself to check that for me, but that didn't work for me as I expected...
For example, I triggered a build that requests the expression "myLabelA ||
myLabelB". Then I programmatically created a Label that would match that.
Yet, Jenkins couldn't match it for some reason:
import hudson.model.labels.*
Jenkins.instance.queue.items.each {
println ">> Label expression from the pending build:"
def labelFromQueueJob = it.getAssignedLabel()
println "Type: " + labelFromQueueJob.class
println "Expression: " + labelFromQueueJob
println ">> countBuildableItemsFor " + labelFromQueueJob + " : " + Jenkins
.instance.queue.countBuildableItemsFor(labelFromQueueJob)
}
println "\n>> Artificially created Label expression:"
LabelExpression artificialLabelExp = new LabelExpression.Or(new LabelAtom(
"myLabelA"),new LabelAtom("myLabelB"))
println "Type: " + artificialLabelExp.class
println "Expression: " + artificialLabelExp
println ">> countBuildableItemsFor " + artificialLabelExp + " : " + Jenkins.
instance.queue.countBuildableItemsFor(artificialLabelExp)
Output:
>> Label expression from the pending build:
Type: class hudson.model.labels.LabelExpression$Or
Expression: myLabelA||myLabelB
>> countBuildableItemsFor myLabelA||myLabelB : 1
>> Artificially created Label expression:
Type: class hudson.model.labels.LabelExpression$Or
Expression: myLabelA||myLabelB
>> countBuildableItemsFor myLabelA||myLabelB : 0
No questions left. I'm glad that you pointed out that curl solution. I've
certainly overlook it!
