Remko Popma commented on LOG4J2-345:
------------------------------------

I see. Looks interesting.
I'm using Subclipse (Subversion plugin for Eclipse) which uses something called 
the "unified diff format".

Can you try again with the {{--no-prefix}} option? Perhaps without the "a/" 
source and "b/" destination prefix I'll be able to apply the patch.

> Hi all Log4j/OSGi experts!
> Yesterday I started to migrate from log4j to log4j2. I replaced all Log4j 1.x 
> bundles with log4j-1.2-api as described here: 
> http://logging.apache.org/log4j/2.x/log4j-1.2-api/index.html
> But I got following error:
> Unresolved constraint in bundle MyBundle [21]: Unable to resolve 21.0: 
> missing requirement [21.0] osgi.wiring.package; 
> (&(osgi.wiring.package=org.apache.log4j)(version>=1.2.0)(!(version>=2.0.0)))
> so...I checked the capabilities of the log4j-1.2-api bundle:
> g! inspect cap * 11
> org.apache.logging.log4j-1.2-api [11] provides:
> -----------------------------------------------
> osgi.wiring.bundle; org.apache.logging.log4j-1.2-api 2.0.0.beta8 [UNUSED]
> osgi.wiring.host; org.apache.logging.log4j-1.2-api 2.0.0.beta8 [UNUSED]
> As you can see logging.log4j-1.2-api doesn't export the log4j API 1.2. It 
> still requires log4j 1.2. All dependent bundles can not be resolved until I 
> add the old log4j.jar.
> The maven-bundle-plugin does not export the packages.
