Re: Classes duplicated when using Embed-dependency

[Felix Meschberger <fm...@gmail.com>]

Hi Anne,

You basically have two choices of adding dependencies to your bundles:
As Export/Private-Package or by embedding as a dependency. If you embed
the dependency as you did, the jar file is included in the bundle as
instructed. You also listed two packages as exported and private
packages. So these classes are put directly into the bundle.

To solve this issue, you might want to inline the dependency inside the
bundle instead of copying the jar file (and of course drop the
Private-Package declaration as it is too much:

        <Export-Package>org.apache.log4j</Export-Package>
        ...
        <Embed-Dependency>*;inline=true</Embed-Dependency>
        
(Just out of my head, I did not actually test :-) )

Or you might just list all packages you want to have included in the
bundles as exported or private packages and just drop the
Embed-Dependency element.

Regards
Felix

the third way is to use <_exportcontents> which lets you customize
the exported packages after the bundle content has been calculated

with this you can put embedded jars and locally compiled classes in
the same bundle and have full control over the exported packages :)
