I searched all the similar questions and solutions, but they do not help. I hope experts like you come up.

The project code has been uploaded into bitbucket: https://[email protected]/tainule/numad-huizhang.git

I have two modules, app and endpoint. Below is from Module:app:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 21
    buildToolsVersion "21.1.2"

    defaultConfig {
        applicationId "edu.neu.madcourse.huizhang1"
        minSdkVersion 14
        targetSdkVersion 21
        versionCode 3
        versionName "2.1"
//        multiDexEnabled true
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

        }
    }
}

dependencies {


    compile fileTree(include: ['*.jar'], dir: 'libs')
    compile "com.android.support:appcompat-v7:21.0.+"
    compile 'com.google.android.gms:play-services:+'

    compile project(path: ':endpoint', configuration: 'android-endpoints')
    compile files('src/main/res/libs/KeyValueAPI.jar')

}

Below is from Module endpoint:

buildscript {
    repositories {
        mavenLocal()
        mavenCentral()
    }
    dependencies {
        classpath 'com.google.appengine:gradle-appengine-plugin:1.9.17'

apply plugin: 'appengine'

targetCompatibility = 1.7

    appcfg {
        oauth2 = true
    }
    endpoints {

        getDiscoveryDocsOnBuild = true

Java Solutions

Solution 1 - Java

It seems you have a jar file or a lib appearing multiple times.

So, remove the .jar file from the lib folder then:

Build > Rebuild

Solution 2 - Java

I had the same problem error that is shown, i solve it by adding

defaultConfig {        
    // Enabling multidex support.
    multiDexEnabled true
}

I had this problem cause i exceeded the 65K methods dex limit imposed by Android i used so many libraries

Solution 3 - Java

I am adding it so that someone in a similar situation might find it helpful.

So, even after multiDexEnabled = true I was getting the same error. I had no duplicate libraries. None of the above solutions worked. Upon reading the error log, I found OutOfMemError issue to be the primary reason and thought of changing the heap size somehow. Hence, this -

dexOptions {
        preDexLibraries = false
        javaMaxHeapSize "4g"
    }

Where "4g" means HeapSize of 4 GB. And it worked! I hope it does for you too.

Solution 4 - Java

For me I had multiple versions of the same library included in /app/libs. I was using Parse and I had both ParseFacebookUtilsV3-1.9.0.jar and ParseFacebookUtilsV4-1.9.0.jar.

Deleting the V3 jar solves the problem.

Solution 5 - Java

Finally I solved this problem by changing compile 'com.google.guava:guava:18.0 ' to compile 'com.google.guava:guava-jdk5:17.0'

Solution 6 - Java

three condition may cause this issue.

differ module have differ jar
in libs had contain jar，but in src alse add relevant source
gradle repeat contain，eg:

compile fileTree(include: [‘*.jar’], dir: ‘libs’)

compile files(‘libs/xxx.jar’)

if you can read chinese ,read hereError:Execution failed for task ':app:dexDebug'.> com.android.ide.common.process.ProcessException: o

Solution 7 - Java

I encountered the same exact error message. I am not quite sure if my solution will solve also your issue.

In Project Structure (app) I changed the Compile SDK Version from API 22 to API 21 and changed Build Tools Version from 22.0.0 to 21.1.2.

When I downloaded the latest API 22 Adroid 5.1, every project I create is using this API and causes me the problem. Maybe, Android Team is looking for a fix for this one.

Solution 8 - Java

I've got this problem after including same classes twice

Solution 9 - Java

I recently migrated one of our corporate projects from Eclipse to Android Studio.

We too got the below error during the migration:

> Error:Execution failed for task ':appName:transformClassesWithDexForDebug'. com.android.build.api.transform.TransformException: com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command '/Library/Java/JavaVirtualMachines/jdk1.7.0_79.jdk/Contents/Home/bin/java'' finished with non-zero exit value 2

To resolve it, we had to do a few things:

Remove/Update duplicate jars/files from libs

> compile 'com.android.support:support-v4:23' compile > 'com.google.android.gms:play-services:9.0.0'

to compile 'com.google.android.gms:play-services:9.0.0'

Set multiDexEnabled to True

> defaultConfig { multiDexEnabled true }

Increase the heap size:

> dexOptions { > incremental true > javaMaxHeapSize "4g" > }

Solution 10 - Java

This could also be the case when you have too many object references. Take a look at the results from the build, esp in the task :dex:multiDebug:

trouble writing output: Too many method references: 67114; max is 65536.

Solution 11 - Java

Try to put this line of code in your main projects gradle script:

configurations { all*.exclude group: 'com.android.support', module: 'support-v4' }

I have two libraries linked to my project and they where using 'com.android.support:support-v4:22.0.0'.

Hope it helps someone.

Solution 12 - Java

I solved the same issue by removing:

compile fileTree(include: ['*.jar'], dir: 'libs')

and adding for each jar file:

compile files('libs/yourjarfile.jar')

Solution 13 - Java

Try to clean and rebuild the project. I had the absolutely same question, this solved it.

Solution 14 - Java

I have the same issue, and solved by change the '+' to a exact number, like compile "com.android.support:appcompat-v7:21.0.+" to compile "com.android.support:appcompat-v7:21.0.0".

This works for me. :)

Solution 15 - Java

I changed :

compile 'com.google.android.gms:play-services:9.0.0'

compile 'com.google.android.gms:play-services-auth:9.0.0'

to :

compile 'com.google.android.gms:play-services-maps:9.0.0'
