Error:(26, 0) Gradle DSL method not found: 'runProguard()'

Question

I'm using android studio 0.9.3 with gradle 'com.android.tools.build:gradle:0.14.+'

apply plugin: 'com.android.application'

android {
    compileSdkVersion 19
    buildToolsVersion '20.0.0'

    defaultConfig {
        applicationId "xxx.xxx.xxx"
        minSdkVersion 16
        targetSdkVersion 19
        versionCode 1
        versionName "1.0.11"
    }

    signingConfigs{
        releaseConfig{
            storeFile file("xxxxxxx")
            storePassword = "xxxx"
            keyAlias = "xxxx"
            keyPassword = "xxxx"
        }
    }

    buildTypes {
        release {
            runProguard false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
            signingConfig signingConfigs.releaseConfig

            // adds version to file name
            applicationVariants.all { variant ->
                def file = variant.outputFile
                variant.outputFile = new File(file.parent, file.name.replace(".apk", "-" + defaultConfig.versionName + ".apk"))
            }
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    // You must install or update the Support Repository through the SDK manager to use this dependency.
    // You must install or update the Support Repository through the SDK manager to use this dependency.
    // You must install or update the Google Repository through the SDK manager to use this dependency.
    // You must install or update the Support Repository through the SDK manager to use this dependency.
    compile 'com.android.support:support-v4:19.+'
    compile 'com.android.support:appcompat-v7:19.+'
    compile 'com.mcxiaoke.volley:library:1.0.6'
    compile 'com.google.code.gson:gson:2.2.+'
}

The project compiled before without any changes in that file, I'm getting: Error:(26, 0) Gradle DSL method not found: 'runProguard()'

How to fix that?

Answer 1

Instead of using runProguard in your gradle file, try using minifyEnabled. This should fix the issue. runProguard is deprecated and soon be stop working.

EDIT

To use minifyEnabled, gradle should be updated to version 2.2 or above.
