Hi Sandeep, That is really a great question, and thank you for bringing up this issue. I would like to see the main SystemML jar (and -sources.jar and -javadoc.jar) in future releases so that we have 8 Apache-approved artifacts (including the new Python artifact) in the maven central repository (in addition to the 4 at http://www.apache.org/dyn/closer.lua/incubator/systemml/0.11.0-incubating). This would allow users to do things such as use SystemML as a library using standard Maven mechanisms. Also, the sources jar and javadoc jar are very useful for developers.
For some background, our 0.10.0 release included 10 artifacts, which I believe caused confusion because it was hard to tell which artifact for users to download and use. For 0.11.0, we had quite a bit of release difficulties, so we ended up with 4 artifacts (2 binary, 2 source), which allowed us to conform to Apache incubator release candidate validation while releasing a huge number of improvements to the project. In future releases, I believe 8 artifacts is probably ideal. These would be: 1 main jar, 1 sources jar, 1 javadoc jar, 2 binary releases, 2 source releases, and 1 python jar.
