Re: [tycho-user] How to ensure that "import-package" results in getting

["David M. Karr" <davidmichaelkarr@xxxxxxxxx>]

I obviously need to learn more about this.  The latest version in a public Orbit repo is older than 4.5.1, and I need 4.5.1.  I don't understand how to use what you're showing me here.

HI David,

Have you had any luck simply making a proper bundle with the version of ANTLR you require following the recipe in orbit:

I have an Eclipse plugin codebase that uses an ANTLR parser. One (perhaps two) of the several plugins references classes in the antlr packages.

I wasn't able to find the required ANTLR version in a p2 repo, so I have one plugin whose only purpose is to use the "maven-dependency-plugin" to specify the dependencies I need to copy, and I have "build-classpath" entries in the manifest to point to the downloaded jars.  I then set this plugin as a dependency of the other plugins that require the ANTLR classes, along with "import-package" to specify the antlr packages required by the plugin.

This seems conceptually correct, but what I'm finding is that if I do a (say) "require-bundle" of bundle "foo" that defines the "com.foo" package, along with an "import-package" of "com.foo", it's entirely possible that if some other bundle in the Eclipse OSGi runtime container exports the "com.foo" package, I could very well get the classes from that other bundle, instead of the bundle I specifically required.

Specifically, I'm finding that the "checkstyle" bundle apparently uses ANTLR and actually exports those packages (for what reason I can't imagine).  When the bundle in my application ends up randomly getting those classes from the checkstyle bundle, I end up with "linkage error" fatal errors.

So, is there some way I can specify in my plugin manifest that when I say "import-package" for "com.foo", I can specify that I ONLY want to get that package from a specific bundle?
