Hi Nicolas! I *think* when you set executors=0 in the master it is not inserted in the computers list. Thus the NPE.
However, if you try to set executors=0 in a slave you will get an error. So I think we can assume that whenever you Computer.currentComputer() returning null, you have a master with 0 executors? So maybe you can try the following code: --- Computer computer = Computer.currentComputer(); if(computer == null) computer = Jenkins.getInstance().createComputer(); // Calls new Hudson.MasterComputer() Node node = computer.getNode(); --- Not the most elegant solution, but hopefully it will give you some direction to follow, or someone else will chime in with a better alternative. Just my 0.02 cents :) Cheers Bruno P.
