Hi, @dudeinthemirror !
My AS is highlighting me androidx.test.InstrumentationRegistry is deprecated.

So, I would recommend to update this line:
android.support.test.InstrumentationRegistry,androidx.test.platform.app.InstrumentationRegistry

hey @atetc, thanks for the heads up! I updated the .csv file.

good job,thanks man.

For ubuntu 18.04

Features

• one command download and execute
• using sed
• linux compatible

Seems to work great in a multi-project build! Thanks for this!

@dudeinthemirror

@kedarmp, very good catch, thanks. I updated the sed predicate to look for the exact word boundary \< \>
