When creating builds using /build, the result is a 201 response where the Location header points to the queue item that represents the new build. Example:
curl -X POST -v "http://jenkins.mycompany.com/job/test-job/build" * Adding handle: conn: 0xf28b90 * Adding handle: send: 0 * Adding handle: recv: 0 * Curl_addHandleToPipeline: length: 1 * - Conn 0 (0xf28b90) send_pipe: 1, recv_pipe: 0 * About to connect() to jenkins.mycompany.com port 80 (#0) * Trying 10.10.10.10... * Connected to jenkins.mycompany.com (10.10.10.10) port 80 (#0) > POST /job/test-job/build HTTP/1.1 > User-Agent: curl/7.32.0 > Host: jenkins.mycompany.com > Accept: */* > < HTTP/1.1 201 Created < Date: Thu, 29 May 2014 16:38:29 GMT * Server Jetty(8.y.z-SNAPSHOT) is not blacklisted < Server: Jetty(8.y.z-SNAPSHOT) < Location: http://jenkins.mycompany.com/queue/item/3901/ < Content-Length: 0 < Connection: close < Content-Type: text/plain; charset=UTF-8 < * Closing connection 0
For parameterized builds we must use /buildWithParameters instead, however the response from /buildWithParameters does not contain the queue location:
$ curl -X POST -v "http://jenkins.mycompany.com/job/parameterized-test-job/buildWithParameters" * Adding handle: conn: 0xa63c30 * Adding handle: send: 0 * Adding handle: recv: 0 * Curl_addHandleToPipeline: length: 1 * - Conn 0 (0xa63c30) send_pipe: 1, recv_pipe: 0 * About to connect() to jenkins.mycompany.com port 80 (#0) * Trying 10.10.10.10... * Connected to jenkins.mycompany.com (10.10.10.10) port 80 (#0) > POST /job/parameterized-test-job/buildWithParameters HTTP/1.1 > User-Agent: curl/7.32.0 > Host: jenkins.mycompany.com > Accept: */* > < HTTP/1.1 302 Found < Date: Thu, 29 May 2014 16:41:09 GMT * Server Jetty(8.y.z-SNAPSHOT) is not blacklisted < Server: Jetty(8.y.z-SNAPSHOT) < Location: http://jenkins.mycompany.com/job/parameterized-test-job/ < Content-Length: 0 < Connection: close < Content-Type: text/plain; charset=UTF-8 < * Closing connection 0
The expected response to this request is a 201 with the Location header containing the URL of a queue item (exactly what /build does).
