[workflow plugin] stage concurrency

[Patrick Bruneton]

Hi all,

I tried a very simple workflow with a stage running a job, and concurrency set to 2:

node('windows') {

   stage name: 'Build', concurrency: 2

   build 'build'

}

I have allowed the job 'build' to have multiple runs in parallel (works fine if I trigger the jobs manually multiple times).

However, if I trigger my workflow multiple times, executions of the job 'build' are serialized where I expect to have two runs in parallel.

Did I miss something? Or is it a know issue?

Thanks for your help,

Patrick

First things first, I'm assuming there are at least two nodes in the cluster
with the 'windows' label right?


That said, it's probably better to put the stage *ahead* of the node
allocation, that way you won't end up allocating 10 nodes but only executing
the build two at a time.


Past that, I'm not sure what might not be working
