Debug Build Failing with current build.gradle configuration

Attached screenshot.
Just git cloned the repo and tried to perform a clean build

Think problem is because of missing testCompile dependency on junit.
Once I add those, it starts giving out other warnings.Attached Screenshot

if you look at the dependencies, it shows that one of the dependency is using version 23.1.1 for support-annotations library

on running ./gradlew -q :app:dependencies
Have a look at generated dependencies graph

in project level build.gradle file we have
classpath 'com.frogermcs.androiddevmetrics:androiddevmetrics-plugin:0.4'
which uses 23.1.1 libraries

Project builds successfully when you go to an earlier commit - d213a1e
before #19
