如何更改hpi的端口号：运行

Question

I'm trying to run the below command to package the hpi file in target folder

 hpi:run

And observed the below error message that says the port has been used already. I just tried to kill the port by manually but i don't have privilege to do that. Is it possible to customize the port no by passing as an argument -Dhpi.port=xxx something like this?

Exception:

From Jenkins documentation:

Runs Jenkins with the current plugin project. This only needs the source files to be compiled, so run in the compile phase.
To specify the HTTP port, use -Djetty.port=PORT

So, try to use -Djetty.port=PORT parameter.
