Compiling error on pentaho-platform from github

Hi dears,

I have cloned github repository,
after that i have created the following projects.

pentaho-platform-api
pentaho-platform-assembly
pentaho-platform-core
pentaho-platform-extensions
pentaho-platform-repository
pentaho-platform-scheduler

pentaho-user-console

But i am not able to add jar files in build path because cloned repository folder "pentaho-platform" does not contain any folder like jar.

If any one knows how to build it then please let me know.

Best Regards
