Jenkins refuses to queue and run identical consecutive build requests from curl

[Martin d'Anjou]

I try to trigger multiple builds rapidly using curl, but Jenkins silently refuses to launch the builds. It keeps returning the same queue item in the "Location":

$ curl -I -X POST "http://localhost:8080/job/test-123/buildWithParameters/params?foo=i"
HTTP/1.1 201 Created
Date: Wed, 18 Apr 2018 00:06:32 GMT
X-Content-Type-Options: nosniff
Location: http://localhost:8080/queue/item/17/
Content-Length: 0
Server: Jetty(9.2.z-SNAPSHOT)

$ curl -I -X POST "http://localhost:8080/job/test-123/buildWithParameters/params?foo=i"
HTTP/1.1 201 Created
Date: Wed, 18 Apr 2018 00:06:34 GMT
X-Content-Type-Options: nosniff
Location: http://localhost:8080/queue/item/17/
Content-Length: 0
Server: Jetty(9.2.z-SNAPSHOT)

What's wrong? How do I get Jenkins to queue all my build requests?

From my understanding this will happen it the "same looking" item goes into the
queue and isn't dequeued rapidly enough.

So basically if the quiet period is really low, these subsequent calls might
queue redundant items once one item is actually dequeued.


Anyways, that's my understanding of this behavior.
