Gradle DSL method not found: 'runProguard'

If you are using version 0.14.0 or higher of the gradle plugin, you should replace "runProguard" with "minifyEnabled" in your build.gradle files.

runProguard was renamed to minifyEnabled in version 0.14.0. For more info, See Android Build System

Using 'minifyEnabled' instead of 'runProguard' works properly.

Previous code:

buildTypes {        release {            runProguard false            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'        }    }

Current code:

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

Hope this helps.

If you are migrating to 1.0.0 you need to change the following properties.

In the Project's build.gradle file you need to replace minifyEnabled.

Hence your new build type should be

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

Also make sure that gradle version is 1.0.0 like

classpath 'com.android.tools.build:gradle:1.0.0'

in the build.gradle file.

This should solve the problem.
