I'm still not able to use setNumExecutors. I was able to use setNodeLabel
though with the following code in script console:
for (slave in jenkins.model.Jenkins.instance.slaves) {
oldLabelName = slave.getLabelString()
println("Label= $oldLabelName")
if (oldLabelName.contains('synth')) {
println("Found $oldLabelName")
newLabelName = oldLabelName + " " + "EXTRALABEL"
slave.setLabelString(newLabelName)
numexecutors = slave.getNumExecutors()
println("executors=$numexecutors")
//slave.setNumExecutors(1)
}
}
This proved that I can access a slave and modify parts of it (the label),
but when I uncomment the setNumExecutors line, I get the following error:
groovy.lang.MissingMethodException: No signature of method:
hudson.slaves.DumbSlave.setNumExecutors() is applicable for argument types:
(java.lang.Integer) values: [1]
Possible solutions: getNumExecutors(), getNumExecutors()

A bit more research and I found this, though I'm not clear on the final
response from Jesse Glick.

It appears he's saying that modifying the number of executors is possible, but
you need to replace the whole slave? Not sure how to do this - it would be a
lot easier if I could just call setNumExecutors.
