Error:Execution failed for task ':app:dexDebug' error in my project while I added new dependency

Question

I didn't added any libraries / jars in my project( in libs ) only this dependencies.

My build.gradle file.

android {
compileSdkVersion 23
buildToolsVersion "23.0.1"

defaultConfig {
    applicationId "com.android.example23"
    minSdkVersion 14
    targetSdkVersion 23
    versionCode 1
    versionName "1.0"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'),    'proguard-rules.pro'
     }
 }
}

dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.1.1'
compile 'com.android.support:cardview-v7:23.1.1'
compile 'com.android.support:recyclerview-v7:23.1.1'
compile 'com.android.support:support-v4:23.1.1'
compile 'com.melnykov:floatingactionbutton:1.1.0'
compile 'com.android.support:design:23.1.1'
compile 'org.apache.directory.studio:org.apache.commons.io:2.4'
compile 'com.google.android.gms:play-services:8.3.0'
compile 'com.squareup.picasso:picasso:2.5.2'
compile 'com.parse:parse-android:1.11.0'
compile 'com.naver.android.helloyako:imagecropview:1.0.3'
compile 'com.squareup.okhttp:okhttp:2.6.0'
}

Once I am adding this " compile 'com.squareup.okhttp:okhttp:2.6.0' " into my project I am getting this

Error:Execution failed for task ':app:dexDebug'.

com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command 'C:\Program Files\Java\jdk1.8.0_45\bin\java.exe'' finished with non-zero exit value 2

Error is coming while I run my project....

If I remove this " compile 'com.squareup.okhttp:okhttp:2.6.0' " dependency my program is working fine.

Sometimes if I added Facebook dependency also the same error is coming...

Answer 1

you can use below code also with IntelliJ Amiya answer. In some case this code work for me

 dexOptions {
    incremental true
    javaMaxHeapSize "4g"
}

android {
compileSdkVersion 23
 buildToolsVersion "23.0.1"

     defaultConfig {
         minSdkVersion 14 //lower than 14 doesn't support multidex
         targetSdkVersion 22

         // Enabling multidex support.
         multiDexEnabled true
     }
}

you can do by make an Application class

public class MyApplication extends MultiDexApplication { .. }

or

override 
 attachBaseContext method and call MultiDex.install().
protected void attachBaseContext(Context base) {
super.attachBaseContext(base);
MultiDex.install(this);
}

Otherwise (if your application does not have custom Application implementation), declare MultiDexApplication as application implementation in your AndroidManifest.xml.

<application
android:name="android.support.multidex.MultiDexApplication"
.. >
..
</application>
