Jenkins - restrict where this project can be run option with && (and) option fails

Question

I have a master and two slaves. When i want a job to run on both the salves i put in this expression in the Restrict where this project can be run option

linux && linux2

I have labelled the nodes correctly. But then the jobs dont run on any machines. I get an error such as Theres no slave/cloud that matches this assignment and the the job is still pending saying it cannot find a label matching the expression. Whats wrong? How can i make it run on both slaves. I do not want to use any other plugin.

Answer 1

Your expression says that a machine must have two labels: linux and linux2.

You most likely want to say linux or linux2, which would be linux || linux2.
That would mean, when you start a build, that it runs on either one of those two machines.

If you want the build to occur on both machines when you start a build, you could install the Node Label Parameter plugin, mark your job as "This project is parameterized", add a "Node" parameter, choosing linux and linux2 under "Default nodes", and then choose "Execute concurrent builds if necessary", so that builds can happen on both machines at the same time.
