Change the AutoValue pom.xml so that it uses the Maven shade plugin to include all dependencies in the generated jar, and to rename most of them. This is intended to address https://github.com/google/auto/issues/156.
You need to attach the shaded jar as well if you want it deployed on release to maven, and then fix the usage instructions to prefer teh shaded jar.  Attachment docs here:
