Spotbugs sequential execution as gradle task about discuss HOT 5 OPEN

Hi. In case of Jenkins, I would recommend using Locable Resources Plugin (https://www.jenkins.io/doc/pipeline/steps/lockable-resources/).
https://stackoverflow.com/questions/56786164/jenkins-resource-locks-get-lock-for-multiple-node-specific-resources/58393432#58393432 also very well shows how you can make the locks node-specific so that it would allow different nodes to run different static analysis builds.

@lasselindqvist Thanks for your quick answer bro.
So if I understand right, this plugin allows you to lock specific amount of RAM memory for some Jenkins job build step.

But I think that the problem is not related to Jenkins, because I just want to make spotbugs task sequential, in other words if at some point in time spotbugs is running for some java module, I want gradle to finish that task before start next spotbugs task for another module.

If I have 8 modules and Jenkins runs 8 parallel gradle tasks, for example:
Module1.compile(requires a little bit of memory and needs some seconds to finish)
Module2.compile(requires a little bit of memory and needs some seconds to finish)
Module3.compile(requires a little bit of memory and needs some seconds to finish)
Module4.compile(requires a little bit of memory and needs some seconds to finish)
Module5.compile(requires a little bit of memory and needs some seconds to finish)
Module6.compile(requires a little bit of memory and needs some seconds to finish)
Module7.compile(requires a little bit of memory and needs some seconds to finish)
Module8.spotbugs(requires 1GB RAM and needs some extra minutes to finish)

Compile gradle tasks will finish faster than spotbugs one, and if gradle start another spotbugs task for some modules, for example:
Module1.spotbugs
Module2.test
Module3.spotbugs
Module4.spotbugs
Module5.spotbugs
Module6.spotbugs
Module7.test
Module8.spotbugs

At that moment the job will need more than 6GB of RAM and I don't have that much.
I don't know if you understand me right :)

I just need to tell gradle: "Hey, don't run spotbugs, because another module is now using that gradle task"

Best regards, Mario :)

If you just want one spotbugs at a time, the situation is even simpler for you. Just use

lock(label: 'spotbugs') {
    // gradle spotbugs command goes here
}

and it will only allow one single command globally.

@lasselindqvist Thank you man, appreciate your help. Can this plugin be used in Jenkins freestyle job instead of pipeline?

from discuss.

I would think you can. Best way to find out is to just install the plugin and try using it.
