Android Execution failed for task app:proguardRelease

Question

I am unable to generate a signed APK for my app, I am stuck with the error java.io.IOException Execution failed for task:'app:proguardRelease' I have what I think is a basic gradle file see below

apply plugin: 'com.android.application'

android {
    compileSdkVersion 21
    buildToolsVersion "21.1.1"

    defaultConfig {
        applicationId "com.okason.clients"
        minSdkVersion 16
        targetSdkVersion 21
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.google.api-client:google-api-client:1.19.0'
    compile 'com.google.android.gms:play-services:6.1.71'
    compile 'com.android.support:support-v4:21.0.0'
    compile 'com.android.support:appcompat-v7:21.0.0'
}

The generated Proguard-rules.pro file is empty amd I have not touched the proguard-android.txt file in the SDK. I even tried to copy this file to the root of app to be the same location as the app.gradle file without success.

I tried to run this command gradlew.bat assembleRelease per this [SO Question][1] with success. Please can someone take a look and let me know what I am doing wrong. I have update the SDK and Android Studio to the latest versions.

What's the exact error you're getting? There's all sorts of IOExceptions. — Scott Barta, Dec 16 '14 at 17:30

I think Sir you can avoid the error without turning off the Proguard. Check this answer by Sir Eric Schlenz with regards to this issue. In order to just get to a point where the build would get through proguard, You have to add -dontwarn entries for packages it was complaining about to your proguard-project.txt file.

Solved the problem by setting minifyEnabled true to minifyEnabled false in the app.gradle file

But that just turns Proguard off, doesn't it. What if I still want proguard enabled? – Suragch Jan 20 '15 at 13:44

Sinenes's answer about using -nowarn should be the accepted answer. Not this. – Logic1 Jan 21 '16 at 21:18

the correct solution should solve include proguard enable – amorenew Mar 20 '17 at 09:39
