Agreeing with @andaag - you don't want to compile the Android core classes into the Volley JAR - so platform dependency scope needs to be "provided", as per -

<dependency>
  <groupId>com.google.android</groupId>
  <artifactId>android</artifactId>
  <version>4.1.1.4</version>
  <scope>provided</scope>
</dependency>

I have added sources and javadoc attach to a script.
