Error:Execution failed for task ':app:transformClassesWithDexForDebug'

Question

The error

Error:Execution failed for task ':app:transformClassesWithDexForDebug'. com.android.build.transform.api.TransformException: com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command '/usr/lib/jvm/java-8-oracle/bin/java'' finished with non-zero exit value 1

My app gradle file:

apply plugin: 'com.android.application' apply plugin: 'com.google.gms.google-services'  android {     compileSdkVersion 23     buildToolsVersion "23.0.1"     defaultConfig {         applicationId 'Hidden application ID'         minSdkVersion 15         targetSdkVersion 23         versionCode 1         versionName "1.0"         multiDexEnabled true     }     buildTypes {         debug {             minifyEnabled false             proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'         }         release {             minifyEnabled true             proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'         }     }     lintOptions {         disable 'InvalidPackage'     }     packagingOptions {         exclude 'META-INF/services/javax.annotation.processing.Processor'     }     productFlavors {     } }  repositories {     mavenCentral() }  dependencies {     compile fileTree(include: ['*.jar'], dir: 'libs')     compile 'com.android.support:multidex:1.0.1'     compile 'com.android.support:appcompat-v7:23.1.1'     compile 'com.android.support:design:23.1.1'     compile 'com.android.support:cardview-v7:23.1.1'     compile 'com.jakewharton:butterknife:7.0.1'     compile 'com.mcxiaoke.volley:library-aar:1.0.0'     compile 'com.google.android.gms:play-services:8.1.0'     compile 'com.facebook.android:facebook-android-sdk:4.7.0'     compile 'com.googlecode.libphonenumber:libphonenumber:7.2.1'     compile 'com.getbase:floatingactionbutton:1.10.1'     compile 'com.android.support:preference-v7:23.1.1' } 

While debugging, if I set minifyEnabled to true, then it compiles. However, then I cannot debug my application.

I checked this other question: Execution failed for task ':app:transformClassesWithDexForDebug' while implementing Google sign in for Android, but there is only one answer and implementing it does not resolve the issue unfortunately.

AFAIK, the error is caused due to addition of too many Gradle dependencies, but I may be wrong (I really hope to be wrong because all these packages are really important!).

Please help me to resolve this error. Much thanks!

Just correct Google play services dependencies:

You are including all play services in your project. Only add those you want.

For example , if you are using only maps and g+ signin, than change

 compile 'com.google.android.gms:play-services:8.1.0' 

to

compile 'com.google.android.gms:play-services-maps:8.1.0' compile 'com.google.android.gms:play-services-plus:8.1.0' 

From the doc :

In versions of Google Play services prior to 6.5, you had to compile the entire package of APIs into your app. In some cases, doing so made it more difficult to keep the number of methods in your app (including framework APIs, library methods, and your own code) under the 65,536 limit.

From version 6.5, you can instead selectively compile Google Play service APIs into your app. For example, to include only the Google Fit and Android Wear APIs, replace the following line in your build.gradle file:
compile 'com.google.android.gms:play-services:8.3.0'
with these lines:

compile 'com.google.android.gms:play-services-fitness:8.3.0'
compile 'com.google.android.gms:play-services-wearable:8.3.0'
