Kars not expanding into karaf/data/kar directory

[Paul Fraser <pa...@qnenet.com>]

Hi,

Karaf 4.3.6, Ubuntu 20.04

Copy kar into deploy directory and the expanded kar is not in the  
karaf/data/kar directory.

In a clean install on a new vps it creates a new .m2 directory and 
places the kar contents there.

When run on an existing system with an existing .m2 repo the system runs OK.

If I rename the existing .m2 it creates a new one and the system does 
not start.

Has anyone experienced this situation?

The problem prevents an installation of a karaf based system from 
running on a fresh vps.

Hi,

It's because in etc/org.ops4j.pax.url.mvn.cfg file, by default you can
see org.ops4j.pax.url.mvn.localRepository points to
$USER/.m2/repository.
Wherever the artifacts are coming (from kar included), the artifacts
are cached in .m2 repository.

On the other hand, you can see:

org.ops4j.pax.url.mvn.defaultRepositories=\
    ${karaf.home.uri}${karaf.default.repository}@id=system.repository@snapshots,
\
    ${karaf.data.uri}kar@id=kar.repository@multi@snapshots, \
    ${karaf.base.uri}${karaf.default.repository}@id=child.system.repository@snapshots

it's where you can see the kar mvn repository.

So, by default, you will have the artifacts in both kar repository and .m2.

Regards
JB
