Re: [tycho-user] dependency on a fragment in a sibling project

Thanks so much Jan!
   I am not, intentionally anyway, attempting a split package.  I will
work up a small self contained example to make more clear...  In the
meantime it may be useful to know that the reason I am creating a fragment
is that I am attempting to add some capability to an eclipse-plugin that I
do not own, or have the source for.  I think I could get the third party
plugin to add the functionality that I need but, their release cycle won't
get it out the door before my release cycle comes.  So I need to modify
their plugin in this way (I think).

I ran into this fragment issue in the Eclipse PDE environment as well.  I
was able to solve my compile time problems in PDE through the use of
Eclipse-ExtensibleAPI manifest header.   As described here:

Yes, that means I had to crack the 3rd party bundle, add that manifest
header to the manifest and repackage the bundle.  Yuck! I'm only willing
to do that because the header is addressing an Eclipse PDE issue and
shouldn't be needed in the OSGI container.  The bundle and the fragment
should get fused.  Or said another way:  From what I understand this
shouldn't be an issue at runtime when the bundle and its fragment are
deployed into Equinox because the container will treat them as one bundle
and I'm home free.

I spent the vast portion of the day working out side issues, so that I
could verify that I really do need this bundle and fragment in this way.
Turns out I do, so I now really need to work out the tycho build part of
the problem.  I will cook up a small self contained example and send it
out ASAP.
