Jenkins wants vncserver on Mac

I want to set up Jenkins local server on Mac mini for Android CI. I configured whole thing, but I have some issues with vncserver, when I try to run build via Jenkins it gives me an error :

I installed vnc server from here https://www.realvnc.com/download/vnc/ but it did nothing, cause I still have this error. What to do ?

Why it fails

You have installed the Xvnc plugin, and it indeed requires a vncserver. Jenkins tries to run the vncserver command by default, and thus expects it in the PATH. The VNC server you installed:

  1. is not installed in your PATH
  2. isn't named vncserver

so it won't work.

Check you requirements!

Do you need to run a vncserver at all ? Usually this is required for headless displays, but your mac mini probably runs with a screen attached, so you probably can just disable the Xvnc plugin on that server...

Getting a vncserver to run anyway

If you really need the plugin, then either configure the commandline option to start the vncserver you installed or find a vnc server that will satisfy the above 2 requirements (command name and in PATH).

Note: the product you installed contains both a VNC client and a server. The server requires a license and an activation. And the server usually runs as a daemon, so doesn't need to have a plugin to start it...
