Re: [equinox-dev] Exporting the entire bundle?

[Rafael Chaves <Rafael_Chaves@xxxxxxxxxx>]

This is not actually a problem because
although package-prefixes are declared per library in the plug-in manifest,
during runtime the classloader creates a single unified package-prefix
specification for all libraries, so the binding between library and package-prefixes
is lost (DJ has confirmed this).

True.  How do you use this information?

There is a subtle difference: package prefixes are on each library, while
Provide-Package is for the bundle. If a bundle has three libraries, one
cannot tell where the packages are coming from when listed in Provide-Package.

The only difference in Equinox is that export="*" is not supported.
 That is, you have to list all of the packages you want to export
in the Provide-Package header.

This is very similar to the Eclipse package prefixes notion but more explicit.
 Note that a tool could provide export=* style support but under the
covers compute the set of packages in the plugin and update the manifest.
 This is what the plugin converter does.

In Eclipse, there is a way to export the entire library using:

<runtime>
 <library name="xyz.jar" export="*"/>
</runtime>

There seems to be no direct way of expressing the same using the new
'ProvidePackage' header. I am curious why 'RequireBundle' was added to
aid
Eclipse porting for exporting a library was not.
