If you look at the other quickstarts, you'll notice they prefix the artifactId with `jboss-as-`. The reason we do this is to make sure the deployment is unique and prevent a quickstart from accidentally wiping out a deployment with the same name. So in this case it should be:
`<artifactId>jboss-as-cdi-decorator</artifactId>`

It looks like we need to update our Contributing Guide because it's missing this information. Sorry about that.
