Can't build the test project

[DavidBarishev]

Hello!
I Hope this repository isn't dead, it's really usefull. I have cloned it and tried to build the test's project, but without any success.The only thing i changed the target API version to 19.

Here is the error i couldn't resolve :

Error       The "CheckDuplicateJavaLibraries" task failed unexpectedly.
System.IO.FileNotFoundException: Could not find file 'D:\Program Files\Android\android-sdk\extras\android\support\multidex\library\libs\android-support-multidex.jar'.
