Hi,
when I tried to declare an exact version match using Eclipse 3.2. RC1a,
a bunch of problems came my way. For one, the manifest editor doesn't
store the maximum version
<https://bugs.eclipse.org/bugs/show_bug.cgi?id=139224> (although one can
input it in the editor). But what seems to be the bigger problem is that
the resulting classpath for my plugin does not seem to match the
versions I specified.
In my configuration I have both EMF 2.2.0 and 2.1.1 present, and I
specified the following:
org.eclipse.emf.codegen;bundle-version="2.1.1";version-match=minor;visibility:=reexport,
org.eclipse.emf.codegen.ecore;bundle-version="2.1.1";version-match=minor;visibility:=reexport,
org.eclipse.emf.importer;bundle-version="2.1.1";version-match=minor;visibility:=reexport,
org.eclipse.emf.importer.java;bundle-version="2.1.1";version-match=minor;visibility:=reexport,
After chosing "Update Classpath" I end up with an interesting mixture of
versions both 2.2.0 and 2.1.1.
There had been some discussion of a new syntax for specifying version
matches < http://dev.eclipse.org/mhonarc/lists/equinox-dev/msg00301.ht ml>
but I'm not sure whether that is supposed to work or not (the Manifest
editor doesn't like it at all, that's for sure).
Could someone of the Equinox experts comment on whether the above exact
version match is supposed to work or whether it is even tested to work
with the PDE's "Update classpath..." facility?
Thanks,
J

You should use the version range syntax in the bundle-version attribute
org.eclipse.emf.codegen;bundle-version="[2.1.1,2.1.2)";visibility:=reexport,
org.eclipse.emf.codegen.ecore;bundle-version="[2.1.1,2.1.2) ";visibility:=reexport,
org.eclipse.emf.importer;bundle-version="[2.1.1,2.1.2)";visibility:=reexport,
org.eclipse.emf.importer.java;bundle-version="[2.1.1,2.1.2) ";visibility:=reexport,
The version range of "[2.1.1,2.1.2)" indicates anything from 2.1.1 up to
but not including 2.1.2. PDE UI does support the version range syntax
when specifying the properties of your required plug-ins or imported
packages.

Thanks Tom, that works!
Some of the EMF plugins of that particular release are versioned 2.1.0,
some 2.1.1, so I'm using the following now:
org.eclipse.emf.codegen;bundle-version="[2.1.0,2.1.1]";visibility:=reexport,
org.eclipse.emf.codegen.ecore;bundle-version="[2.1.0,2.1.1] ";visibility:=reexport,
org.eclipse.emf.importer;bundle-version="[2.1.0,2.1.1]";visibility:=reexport,
org.eclipse.emf.importer.java;bundle-version="[2.1.0,2.1.1] ";visibility:=reexport,
Regards,
Jörg

It seems that was a bit too early. After a few restarts, the PDE editor
now claims that the version constraints cannot be satisfied. Again I'm
seeing a funny versions mixtures in the "Plug-in Dependencies" classpath
containers. When I look at "Help / About Eclipse SDK / Plug-in Details",
I can see all required versions, though (next to the larger versions I
don't require).
I had exported my plugins while it worked (using a Windows box, for some
reason it complained about a version 0.0.0 of my plugin not found or
something on the Linux box), then installed them and now my two plugins
are happily running from within my Eclipse configuration.
Maybe there is a problem related to resolving versions within the
workspace, as it seems to work in the normal runtime environment.

It seems that the particular EMF plugins that I need cannot coexist in
different versions. To me it looks like only the largest version gets
loaded (while other EMF plugins can coexist in different versions). I
somewhat lost overview how that can happen, could it be due to an old
plugin.xml format, missing MANIFEST.MF or bad feature.xml or something
like that?
However, I can live with it (and we'll have to migrate to the latest
version sooner or later anyway...)
Thanks for answering,
Jörg

Joerg,
These plugins cannot coexist in different versions because they are
singleton bundles - ie you can only have one instance of the bundle
running, irrespective of versioning.
Unfortunately that is a requirement of any bundle that contributes to the
extension registry.

Thanks for that information! Just for the records, this seems to be the
same issue as discussed in thread "The RSP bundle must be singleton?",
relating to bug https://bugs.eclipse.org/bugs/show_bug.cgi?id=137574
