Lockable Resources
resource: testing1-repository, labels:testing-repository
resource: testing2-repository, labels:testing-repository
resource: testing3-repository, labels:testing-repository
Configured these 3 resources in Jenkins. Different resource name and same
label on all three resources.
Pipeline script:
def stepsForParallel = [:]
stepsForParallel["nodeName1"] = transformIntoStep("nodeName1")
stepsForParallel["nodeName2"] = transformIntoStep("nodeName2")
stepsForParallel["nodeName3"] = transformIntoStep("nodeName3")
stepsForParallel["nodeName4"] = transformIntoStep("nodeName4")
parallel stepsForParallel
def transformIntoStep(nodeName) {
return {
node("master") {
if (nodeName.equals("nodeName4")) {
lock(label: "testing-repository") {
println "Testing lock label"
sleep 20
}
} else {
sleep 5 /* to make sure nodeName4 aquires its lock first. */
if (nodeName.equals("nodeName1")) {
lock(resource: 'testing1-repository') {
println "Testing lock resource"
sleep 10
}
}
if (nodeName.equals("nodeName2")) {
lock(resource: 'testing2-repository') {
println "Testing lock resource"
sleep 10
}
}
if (nodeName.equals("nodeName3")) {
lock(resource: 'testing3-repository') {
println "Testing lock resource"
sleep 10
}
}
}
}
}
}

Does not work as I expected it to.
When nodeName4 releases the testing-repository which contains 3 resources,
then the other can acquire the lock on their resources. However only one of
them does so, the others do not. The entire build hangs and goes no
further.
[nodeName1] Lock acquired on [testing1-repository]
[nodeName4] Lock released on resource [Label: testing-repository]
[nodeName1] Lock released on resource [testing1-repository]
Do not know why nodeName1 acquired the lock before nodeName released.
This is the output I expected:
[nodeName4] Trying to acquire lock on [Label: testing-repository]
[nodeName4] Lock acquired on [Label: testing-repository]
[nodeName4] Lock released on resource [Label: testing-repository]
[nodeName1] Lock acquired on [testing1-repository]
[nodeName2] Lock acquired on [testing2-repository]
[nodeName3] Lock acquired on [testing3-repository]
[nodeName1] Lock released on resource [testing1-repository]
[nodeName2] Lock released on resource [testing2-repository]
[nodeName3] Lock released on resource [testing3-repository]
