Remove a Queue item through a Groovy script

[tiago fernandez]

Hello,

 

I want to cancel a Queue item through a groovy script.

The script I have is something like this   (I do a post because it is specified that to remove an queue item. And queue item id I obtain it from another part of the code using json api):

 

def urlString = 'http://<jenkins.server>/queue/cancelItem'

def queryString = "id=" + item.id

def url = new URL(urlString)
def connection = url.openConnection()
connection.setRequestMethod("POST")
 

connection.setDoInput(true);
connection.setDoOutput(true);

connection.connect()
  

def writer = new OutputStreamWriter(connection.outputStream)
writer.write(queryString)
writer.flush()
writer.close()
 

def inStream = new DataInputStream(connection.getInputStream())

def buffer
while((buffer = inStream.readLine()) != null) {
       println(buffer);
}
 

inStream.close()

connection.close()

 

 

 

 

When I execute this script the item is deleted from the queue, but I get the following error, I think it is because in some point of the code it 'executes' the url deleting the item from the queue, so then it doesn't exist anymore, so when it tries to do the getInputStream it throws the error because the Source URL doesn't exist anymore

Someone has any alternative idea I could implement for this?:

Thanks for the help.

There is no output. It just sends a redirect to the referer location. In your case. that's undefined, which probably causes it to fail this way. Just ignore any non-error response (or at least, any redirects).
