Multi configuration Matrix job fails to start emulator with some errors

I am creating a multi configuration Matrix job to run my tests on multiple emulators on Jenkins but it is failing and emulator does not start. Following is the console output on job:

Solution

Answering the question for others. I figured this way back but forgot to answer. This was happening as Jenkins has an option in configuration under Manage Jenkins > Configure System which is - Keep emulators in the job workspace, in the .android subdirectory, to isolate them as much as possible. If we keep this checked then this error occurs with jobs using multi config matrix.

Hope this helps!
