Gradle refresh failed… here is a solution to the problem.
Gradle refresh failed
Every time I try to add, compile 'com.soundcloud.android:android-crop:1.0.0@aar'
I get the following error
Error:Timeout waiting to lock buildscript class cache for build file 'C:\Users\De Untouchable\AndroidStudioProjects\Yora\app\build.gradle' (C:\Users\De Untouchable\. gradle\caches\2.2.1\scripts\build_3aewj3nvnlp7huq0b8xvs2ju1\ProjectScript\buildscript). It is currently in use by another Gradle instance.

Solution
Clear your gradle cache > delete the entire .gradle folder > project directory. Don’t worry about it being recreated. The same goes for the .gradle -> home directory.
You can also go to “file” -> “invalid” – > “cache/restart”.
