why bindings.jar has not source code?

I find bindings.ar has not source code when research cleversafe source code?

We chose not to put the source code in the actual .jar files. This was advantageous to use because we use the build scripts to produce jars for actual binary distributions.

However, the source code should be included with the release in general. Please let us know if the particular code you are looking for is not included in the release.

Perhaps in the future we will create a .zip file containing just code that can be used to attach the code in Eclipse.

I have already build source code for bindings.jar through scripts

thank you
