Android Gradle Plugin Error. Gradle DSL method not found: 'compile()'

Question

This is the exact error I'm getting while making a build in release Variant.

Error:(57, 0) Gradle DSL method not found: 'compile()'

Possible causes:

The project 'spot' may be using a version of the Android Gradle plug-in that does not contain the method (e.g. 'testCompile' was added in 1.1.0). Fix plugin version and sync project

The project 'spot' may be using a version of Gradle that does not contain the method. Open Gradle wrapper file

The build file may be missing a Gradle plugin. Apply Gradle plugin
