All classes are properly compiled and stored in jar files and dependencies are automagically downloaded to make sure everything compiles. Over the last few days I've added packaging of the systemvm.iso to the maven files and I did some work on the awsapi. The awsapi is proving to be difficult as it has multiple results (.mar, .aar, .jar files and a webapp). Maven doesn't really like this. On the other hand, maven has plugins to deal with axis2 and generate everything, so with a  bit of work we should be able to simplify this. Test code is not compiled in some cases as there are some interesting circular references (test code for server depending on vmware plugin comes to mind), that needs to be sorted if we want maven to be able to do its job.

With the exception of awsapi all RPM packages are being built on my dev environment so that is looking good. I don't have a debian environment yet, so I'm not able to test a debian build. I haven't done any testing on the rpms yet, just verified that they are build, hoping to do that tomorrow.

Now we need to either check if our dependencies aren't already supplied by the OS or put them in a different directory, like /usr/share/java/cloud/*jar. What is the best route to take?

I'd not prefix cloud-, to me that hints towards a homebrew version of 
that file.

Whenever a library/JAR is available through the package manager of that 
distribution I'm voting for depending on that with the RPM/DEB packages, 
that is one dependency resolved.

For example the MySQL connector is available under Ubuntu and Debian, I 
already made a commit for that [0].

Placing the rest in /usr/share/java/cloud is fine with me, that way we 
don't pollute the system.
