ukey2 issue

[manu3b1]

After cloning this repo, i get:

* Where:
Build file 'android-auto-companion-android/encryptionrunner/build.gradle' line: 33

* What went wrong:
A problem occurred evaluating project ':encryptionrunner'.
> Project with path ':libs:ukey2' could not be found in project ':encryptionrunner'.

If I clone ukey2 from https://github.com/google/ukey2, i get many other errors linked to its build.gradle content.

What did I miss?
