How to limit Jenkins concurrent multibranch pipeline builds?

Question

I am looking at limiting the number of concurrent builds to a specific number in Jenkins, leveraging the multibranch pipeline workflow but haven\'t found any good way to do

Answer 1

Limiting concurrent builds or stages are possible with the Lockable Resources Plugin (GitHub). I always use this mechanism to ensure that no publishing/release step is executed at the same time, while normal stages can be build concurrently.

echo 'Starting'
lock('my-resource-name') {
  echo 'Do something here that requires unique access to the resource'
  // any other build will wait until the one locking the resource leaves this block
}
echo 'Finish'
