Subject [jira] [Commented] (LUCENE-3172) installation problems on lucene-misc OSGI bundle
Date Sun, 05 Jun 2011 17:58:47 GMT

Gunnar Wagenknecht commented on LUCENE-3172:
--------------------------------------------

FYI, I usually also create an "umbrella" bundle which has a Require-Bundle dependency on all
the Lucene bundles with such split-package headers. It does not contain any class files but
just re-exports the "merged" packages without a split-package header. This allows client bundles
to do a vanilla Import-Package. Otherwise, any downstream client will be forced to add the
special split-package info to their Import-Package declaration.

> lucene-misc contrib module has two package names equals to the core version: org.apache.lucene.index
and org.apache.lucene.store. For theese modules we need to configure the creation of the bundles
so that the OSGI repository recognize theese packages as merged else we get a 'uses constraint
violation' error in the installation.
> The solution is to mark the packages as mergeables adding a configuration in the maven-bunde-plugin:
>         <configuration>
>           <instructions>
>                 <Export-Package>*;-split-package:=merge-first</Export-Package>
>           </instructions>
>         </configuration>
> the * represents the package names. We could put org.apache.lucene.* too
