Android Studio fails to debug with error org.gradle.process.internal.ExecException

Question

I am trying to run the app in debug mode but I get the following error:

Error:Execution failed for task ':app:dexDebug'. > com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command 'C:\Program Files\Java\jdk1.7.0_11\bin\java.exe'' finished with non-zero exit value 2 

Below is my build.gradle file:

buildscript {     repositories {         maven { url 'https://maven.fabric.io/public' }     }      dependencies {         classpath 'io.fabric.tools:gradle:1.+'     } } apply plugin: 'com.android.application' apply plugin: 'io.fabric' apply plugin: 'idea'   repositories {     maven { url 'https://maven.fabric.io/public' } }   android {     compileSdkVersion 21     buildToolsVersion '21.1.1'     defaultConfig {         applicationId 'com.rayat.pricewiz'         minSdkVersion 17         targetSdkVersion 21         versionCode 1         versionName '1.0'     }     buildTypes {         release {             minifyEnabled false             proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'             multiDexEnabled true         }     }     productFlavors {     } }  android {     packagingOptions {         exclude 'META-INF/notice.txt'         exclude 'META-INF/LICENSE.txt'         exclude 'META-INF/license.txt'         exclude 'META-INF/NOTICE.txt'     }     dexOptions {         jumboMode = true         javaMaxHeapSize "4g"     } }  dependencies {     compile 'com.android.support:multidex:1.0.0'     compile files('libs/ksoap2-android-assembly-2.5.8-jar-with-dependencies.jar')     compile files('libs/universal-image-loader-1.9.2.jar')     // You must install or update the Google 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.     compile 'com.google.android.gms:play-services:6.1.71'     compile 'com.android.support:recyclerview-v7:+'     compile files('libs/CWAC-SackOfViewsAdapter.jar')     compile 'com.octo.android.robospice:robospice:1.4.14'     compile 'com.octo.android.robospice:robospice-spring-android:1.4.14'     compile 'com.facebook.android:facebook-android-sdk:3.21.1'     compile('com.twitter.sdk.android:twitter:1.1.1@aar') {         transitive = true;     }     compile files('libs/javax.mail.jar')     compile files('libs/jackson-databind-2.5.0.jar')     compile files('libs/jackson-all-1.9.11.jar')     compile files('libs/jackson-mini-1.9.11.jar')     compile files('libs/scanditsdk-barcodepicker-android-4.2.1.jar')     compile files('libs/nineoldandroids-2.4.0.jar')     compile 'com.squareup.retrofit:retrofit:1.9.0'     compile 'com.squareup.okhttp:okhttp-urlconnection:2.0.0'     compile 'com.squareup.okhttp:okhttp:2.0.0' } 

Can anyone please help as this error is driving me crazy. My code is hitting 65k limit so I added multiDexEnabled option.

EDIT My project architecture

Thanks

Answer 1

That is because you enabled multiDex for release builds only, not for debug builds.

Try this:

defaultConfig {     multiDexEnabled true } 

Answer 2

Try this

dexOptions {     incremental true     javaMaxHeapSize "4g" }
