Eclipse RCP - Use Classes from a library that are imported from another plugin?

follow situation.

-pluiginCore <- includes many Libraries (libA,liB) via pom.xml, do nothing else

-pluginA..F <- want use classes from libA. -pluginF..Z <- want use classes from libB.

Is this possible with RCP? Is this a good way? Do I need to import via pom.xml libA and LibB in each plugin where I wanna use it?

I added pluginCore as a dependency of pluginA but still cant use libA.

You have to do this using the directives in the MANIFEST.MF of the plugins.

For the plugin which contains the libraries you use the Bundle-ClassPath to specifies the jars in the plugin. For example:

Bundle-ClassPath: .,
 lib/jogg-0.0.7.jar,
 lib/jorbis-0.0.15.jar,
 lib/vorbisspi1.0.2.jar

The . entry is for the normal code in the plugin, the other entries are jars in a lib directory.

You must also specify the additional jars in the build.properties for the plugin.

You use the Export-Package directive to say which packages from these jars are available to other plugins:

Export-Package: com.jcraft.jogg,
 com.jcraft.jorbis

Plugins which wish to refer to these packages can either use Require-Bundle to add a dependency to the plugin exporting the packages, or they can use Import-Package to let Eclipse find the imported package.
