I came across below mentioned issue when trying to launch android emulator via Jenkins. I tried to find some solutions in Google and could not get a proper one yet.
Just thought of forwarding this to you to know your input on this.

Scenario:
I wanted to launch Android emulator while running the build in Jenkins so the monkeyTalk scripts can be run once the build is completed and emulator is started. For doing this I added Android Emulator plugin to Jenkins so I can launch the Android emulator as soon as the build id completed.

Issue:
I get below mentioned error message (#2 in the screenshot) when running the build in Jenkins. Just to check whether the same error occurs when running the highlighted commend (#1 in screenshot) in command prompt, I pasted the same command into the command prompt and executed. Then the android emulator started without any issues.
