Saros Server usability
Even if the saros server is in a very early alpha state it would be useful to have some kind of advice (like a common CLI) if you execute the jar.
If you start the server naively (as I did) with `java -jar

After reading the code of ServerConfig.java I knew that I have to set the property saros.server.interactive in order to avoid the exception.
The command java -Dsaros.server.interactive=yes -jar <jar> leads to the next stack trace and a lot of log messages:

The log contains the important information, but it is not really easy to find:
FATAL 09:44:10,786 [main] (ServerLifecycle.java:55) XMPP credentials are missing! Pass the system properties saros.server.jid and saros.server.password to the server
I would propose to implement a simple CLI, which prints the --help context if not all required information are available (instead of starting the server and using properties).
I created #799 to avoid future confusion on how to obtain a Saros server build.
Using wrong connection credentials will result in an exception (which luckily shuts the server down).
