volley

...
<dependency>
  <groupId>com.google</groupId>
  <artifactId>volley</artifactId>
  <version>1.0.0-SNAPSHOT</version>
</dependency>
...

This is missing one very important thing. A provided tag in the dependency. Otherwise it will work fine if the other project is also built with android 4.1.1.4, if it's built with something else it will break the dexing.

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.
