Jenkins command to get number of builds in queue

Question

I am trying to get the number of builds in the Jenkins Build Queue.

May I know the Jenkins command to get the number of builds running in the queue ?

Answer 1

That's easy to do with Jenkins Script Console:

println Hudson.instance.queue.items.length
// => 2

Also that's possible to execute groovy script remotely. For example, from command line:

$ curl -u username:password -d "script=println Hudson.instance.queue.items.length" jenkins_url/scriptText
2

Note: user with specified username should have access to Jenkins Script Console.
