Gradle Warning: missing groovy return statement

With Android Studio 2.2 I had to add a return void before the final bracket in the android section.

android {    compileSdkVersion 24    buildToolsVersion "24.0.2"    defaultConfig {        applicationId "com.example.app"        minSdkVersion 19        targetSdkVersion 24        versionCode 1        versionName "1.0"    }    buildTypes {        debug {            minifyEnabled false            shrinkResources false        }        release {            minifyEnabled true            shrinkResources true            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'        }    }    productFlavors {        standard {            applicationId "com.example.app.standard"        }        free {            applicationId "com.example.app.free"        }    }    // `return void` removes the lint error: `Not all execution paths return a value`.    return void}

I have been getting this same warning and I think it is incorrect. I have read through the gradle documentation and it does not appear that a return type is needed. However, the warnings bug me and the only way I could get rid of it was to add return true.

buildTypes {    android {        release {            minifyEnabled false            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'            return true        }    }}

I doubt this is the "correct" solution; however, it does remove the warnings and it doesn't cause any issues.

I fixed this by adding the recommended suppression string from inspection:

//noinspection GroovyMissingReturnStatementandroid {    compileSdkVersion 25    buildToolsVersion "23.0.3"...
