Dear All.
I just wanted to make a post to the EMF group reporting an error, but
it seems it is not an error, but a problem with Plugin-Dependencies.
Someone told me that cyclic plugin dependencies are not allowed.
Why??
Best Regards, and thanks in advance for any hint,
Philipp Kutter

Hi, Tom.
This is true. On the other hand, if I use the plugins to encapsulate
some packages as OSGi components, it may well be that package 1 needs
package 2, and vice versa.
I read as well that OSGi should allow mutual depencency. Is Eclipse
here not OSGi conform, or did I misunderstand something?
Best, Philipp
PS: I use the web interface to this news group, and our thread is almost
in the last displayed column. Can you please send me a copy of your answer
to
philipp@kutter.org thanks.

Bundle requirements and package import/export are different things. The
former is an extension Eclipse promoted to OSGi in order to support
its existing model of plug-in pre-requisites. The latter is now
available to Eclipse developers becaause it has always been part of OSGi.
Eclipse pre-requisites were always acyclic (since 1.0). Package
imports/exports can form cycles.
For the reasons why cycles are not supported for plug-in pre-requisites:
