I have added recyclerview gradle build and then tried to run the app, and now I get this 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\_79\bin\java.exe'' finished with non-zero exit value 2
> 
> 
> 

Here is my gradle build file:

```
dependencies {
compile 'com.android.support:appcompat-v7:22.1.1'
compile 'com.android.support:recyclerview-v7:22.1.1'
compile fileTree(dir: 'libs', include: 'Parse-*.jar')
compile 'com.parse.bolts:bolts-android:1.2.0'
compile 'com.android.support:design:22.2.0'
compile 'com.google.android.gms:play-services:7.5.0'
compile 'com.facebook.fresco:fresco:0.5.2+'
compile 'com.facebook.android:facebook-android-sdk:4.1.0'
compile fileTree(dir: 'libs', include: 'commons-io-*.jar')
compile fileTree(dir: 'libs', include: 'ParseFacebookUtilsV4-*.jar')
}

```

How to fix this?
