In case of JAR dependencies we can just depend on snapshot in Maven repository:

http://search.maven.org/#search%7Cga%7C1%7Ca%3A%22aerogear-simplepush-server-netty%22

Better, JBoss repository even sometime maintains snapshots:

https://repository.jboss.org/nexus/index.html#nexus-search;quick~aerogear-simplepush-server-netty

You can point to the latest released JAR.

BUT I guess there is no standalone, executable JAR for example SPS, that would be nice suggestion for improvement, wdyt Daniel Bevenius?
