Tomasz,
Sorry for the delay in my reply, I've been extremely busy with work
recently.
I'd like to suggest that you import your plug-ins into your Eclipse
workspace as plug-in projects and run them from there for testing. Then you
won't have to copy them to your Eclipse directory every time you make a
change and you can take advantage of all the Eclipse PDE Tools.
Anyway, on to your problem. You said you saw two new plug-ins,
org.apache.tuscany.sdo.lib and org.apache.tuscany.sdo.spec. Are you also
seeing impl and tools as available plug-ins? If not, that will be a
problem. Also, for the buddy policy to work correctly, the SDO plug-ins
need to depend on each other. Here's how my SDO dependencies are set up in
my manifests:
org.apache.tuscany.sdo.impl depends on
org.apache.tuscany.sdo.spec
org.apache.tuscany.sdo.lib depends on
org.apache.tuscany.sdo.spec
org.apache.tuscany.sdo.impl
org.apache.tuscany.spec and org.apache.tuscany.tools don't need to depend
on the other SDO plug-ins
One final note. What version of EMF are you running with? Tuscany
officially requires EMF 2.2.3, but it may also work with 2.3 (which comes
with Eclipse 3.3). It will NOT work with EMF 2.4, but you probably wouldn't
have that unless you're using Eclipse 3.4.
I hope some of that helps. Write me back with any more questions and I'll
try to be a little more responsive in the future. :-)
Regards,
Eric
