Execution failed for task ':app:dexDebug'.

问题:

I am building my android project when i got this error after import docx4j library in my project. What should i do to get rid of this exception.

Error:Execution failed for task ':app:dexDebug'. > com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command '/usr/lib/jvm/java-7-openjdk-amd64/bin/java'' finished with non-zero exit value 2

回答1:

I had got the same error. But I resolved the issue by adding the following missing line from build.gradle in dependencies. compile 'com.parse.bolts:bolts-android:1.+'

After adding this line, my dependencies body was like this:
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:22.0.0'
compile 'com.parse.bolts:bolts-android:1.+'
compile fileTree(dir: 'libs', include: 'Parse-*.jar')
compile fileTree(dir: 'libs', include: "commons-io-2.4.jar")  }

You can match with yours too and see if it can help you too

回答2:

Add this to your file build. gradle

defaultConfig {
     multiDexEnabled true 
}

回答3:

The Android plugin for Gradle available in Android SDK Build Tools 21.1 and higher supports multidex, so you have to add multiDexEnabled true to your gradle file like below :

android {
    compileSdkVersion 21
    buildToolsVersion "21.1.0"

    defaultConfig {
        ...
        minSdkVersion 14
        targetSdkVersion 21
        ...

        // Enabling multidex support.
        multiDexEnabled true
    }
    ...
}

dependencies {
  compile 'com.android.support:multidex:1.0.0'
}

I might need more information but according to the error on your question:

Error:Execution failed for task ':app:dexDebug'. > com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command '/usr/lib/jvm/java-7-openjdk-amd64/bin/java'' finished with non-zero exit value 2

The IntelliJ compilation way might cause the error you post (at least in my case, it does). I recently came from Eclipse, where a 'Clean Project' is made after every run. In IntelliJ, the project needs a clean build to be run. I've avoided cleaning every time, disabling incremental flag inside dexOptions of the build.gradle.

I ran into the same problem and I did add the multiDexEnabled true in build file but all in vain. But doing the following along with adding multiDexEnabled true in defaultConfig solved my problem.

Add the MultiDexApplication in your manifest like :

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.android.multidex.myapplication">
    <application
        ...
        android:name="android.support.multidex.MultiDexApplication">
        ...
    </application>
</manifest>

And dont forget to add

defaultConfig {
     multiDexEnabled true 
}

The did the trick for me. Ref : Android Studio fails to debug with error org.gradle.process.internal.ExecException

回答6:

the same as my error

Error:Execution failed for task ':app:dexDebug'. > com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command '/usr/lib/jvm/java-7-openjdk-amd64/bin/java'' finished with non-zero exit value 2enter code here

it is because there is a duplication of its dependency lib, in my case like this

compile files('libs/httpcore-4.3.3.jar') compile files('libs/httpmime-4.3.6.jar') compile fileTree(include: ['*.jar'], dir: 'libs')

then I fixed it to be like this compile fileTree(include: ['*.jar'], dir: 'libs') remove other setting import lib

I hope this helps

This Problem can easily be resolved by Removing multiple jar in your project libs folder.
