okey - thats fine - if the plugin is considered an "repackaging" of teiid-embedded.zip then it makes sense.

But if you want to create something else where it is osgi compatible then that is not the case.

but teiid-admin.jar is for running some client app on the shell - not needed by the tools or ?

I think you are missing my point ;) We deliberately avoid exposing runtime stuff as osgi jars because

A) the jars often don't work well in osgi land or even an eclipse plugin world (i.e. anything that loads native code, i.e. jline.jar or custom classes i.e. logging/spring/cdi/hibernate etc.)

B) having tools plugins depend on runtime jars hardens their dependency on runtime versions making it very userunfriendly (i.e. users dont normally need to install a new and old IDE to work with Java 6 and 7 at the same time).

It might be the case for teiid that this cannot be avoided but then Teiid needs to be packaged/distributed in a way that allows easy installation and uninstallation to switch between these versions IMO.
