Eclipse OSGi bundle reqiure another bundle's fragment

This might be simple question but have confused me开发者_如何学运维 for sometime.

I'm developing an OSGi bundle which rely on google guice. Google guice has one main bundle and several fragment like assisted inject fragment. In my bundle I have used the assisted inject fragment and a class that is exported from that fragment.

However in Eclipse, I can only set bundle dependency on another bundel (in this case, the guice bundle) but not directly on a fragment (assisted inject), hence Eclipse complains cannot find the class exported from the fragment.

How can I have the dependency on a bundle's fragment?

Use an Import-Package dependency on the fragment's exported packages.

In fact you should use Import-Package for all your dependencies, and avoid Require-Bundle wherever possible.

In addition to adding the required package to Import-Package, you might need to add Eclipse-ExtensibleAPI: true to the manifest to prevent unresolved dependency error in PDE.
