How to exclude certain file while generating a bundle from jar?

[azaylamba]

Hi,

Can someone please help me with how to exclude certain file from the jar while generating OSGi bundle using p2-maven-plugin? I want to exclude INDEX.LIST file as it is causing issues in my project while loading the jar because of the jar name present in INDEX.LIST is different from the OSGi bundle. I tried using invalidfilenames instructions but it had no impact. I might be using it incorrectly. The instruction format I used is "<_invalidfilenames>INDEX.LIST"

Hi @azaylamba

you have to do it with the underlying bnd tool. It is responsible for repacking of the jar.

Check the donotcopy option of it

Hi @sparsick, thanks for the quick response. I tried donotcopy option with p2-maven-plugin but it didn't work. Can you please confirm whether the plugin supports this or I would need to package my jar using bnd tool only and not using this plugin?

Hi @azaylamba,

you can add BND instruction to your artifact configuration:

<artifact>
    <id>commons-io:commons-io:2.1</id>
    <transitive>true</transitive>
    <source>false</source>
    <override>false</override>
    <singleton>false</singleton>
    <instructions> <!-- here you can out bnd instruction-->
        <Import-Package>*;resolution:=optional</Import-Package>
        <Export-Package>*</Export-Package>
        <_fixupmessages>"Classes found in the wrong directory";is:=warning</_fixupmessages>
        <_removeheaders>Bnd-LastModified</_removeheaders>
        <_reproducible>true</_reproducible>
    </instructions>
    <excludes/>
</artifact>

Here it is described how to put bnd instruction to the plugin. P2 Plugin uses the mechanism of the maven bundle plugin.

I hope that helps.
