Android gradle dependency error for recyclerview
<p>I am using following gradle dependancy:</p>

<pre><code>compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:23.0.1'
compile 'com.google.android.gms:play-services:8.1.0'
compile 'com.android.support:support-v4:23.0.1'

compile files('libs/httpclient-4.1.3.jar')
compile files('libs/httpcore-4.1.4.jar')
compile files('libs/httpmime-4.1.3.jar')
</code></pre>

<p>I am getting following error:</p>

<blockquote>
  <p>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-oracle/bin/java'' finished with non-zero exit value 2</p>
