android – java.exe finished with non-zero exit value 2 when using Facebook SDK-ThrowExceptions

Exception or error:

When I try to compile my app I get a following error

Error:Execution failed for task ':app:dexDebug'.
> org.gradle.process.internal.ExecException: Process 'command 'C:\Program Files\Java\jdk1.7.0_60\bin\java.exe'' finished with non-zero exit value 2

If I get rid of Facebook Android SDK it compiles without a problem.

My build.gradle:

apply plugin: ''

android {
    compileSdkVersion 21 //tried 19 and 22 changing targetSdkVersion and buildToolsVersion accordingly
    buildToolsVersion "21.1.2"

    defaultConfig {
        applicationId "..."
        minSdkVersion 15
        targetSdkVersion 21

    buildTypes {
        release {
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-project.txt'



dependencies {
    compile '' //tried older versions as well
How to solve:

First of all you should try to list your dependencies with gradle :MODULE:dependencies
Check if there are libraries conflicts ( same library but different version ). In this case i supose you should exclude support library module from Facebook SDK.

compile (''){
        exclude group: '', module: 'support-v4'


While using Facebook SDK project library, Pawel’s solution worked for me.

However it stopped working after I had migrated to Gradle dependency ''. Tried to rebuild/reopen project but nothing helped.

This worked for me:

compile ('') {
    exclude module: 'support-v4'
