Different p2 repository content generated on Windows and Linux/MacOS

[jpstotz]

I have some problems that the renerated p2 repo on MacOS/Linux contains artifacts that causes an OSGI dependency error at start-up of my Eclipse RCP based application.

I boiled the problem down to a minimal example which can be started by simply executing mvn (see at the end of this issue). On Windows it creates a a repository with these plugins:

On Linux and MacOS however I get this result (see especially the size of the .httpclient_4.5.13.jar file 764KB vs. 1.4MB):

-rw-rw-r-- 1 user user 328K Sep  2 15:57 org.apache.commons.codec_1.11.0.jar
-rw-rw-r-- 1 user user  61K Sep  2 15:57 org.apache.commons.logging_1.2.0.jar
-rw-rw-r-- 1 user user  32K Sep  2 15:57 org.apache.httpcomponents.fluent-hc_4.5.13.jar
-rw-rw-r-- 1 user user 1.4M Sep  2 15:57 org.apache.httpcomponents.httpclient_4.5.13.jar
-rw-rw-r-- 1 user user 161K Sep  2 15:57 org.apache.httpcomponents.httpclient-cache_4.5.13.jar
-rw-rw-r-- 1 user user 322K Sep  2 15:57 org.apache.httpcomponents.httpcore_4.4.13.jar
-rw-rw-r-- 1 user user  42K Sep  2 15:57 org.apache.httpcomponents.httpmime_4.5.13.jar

Based on the MANIFEST.MF files from the httpclient jar file from Windows respectively Linux it seems like the Windows version has been processed by bnd-tool and the Linux version has not ben processed. I wasn't able to understand which component decides if or if not to process a jar with bnd, therefore I am starting in this project with the issue. Is there any logging I can enable to shed some light on p2-maven-plugin and bnd-tool what they do (or not do)?
