Jean-Baptiste Onofré commented on KARAF-5210:
---------------------------------------------
Any update about this Jira ? Does it still happen with Karaf >= 4.1.3 ?
> Seemingly random NPEs from Aether resolver
> ------------------------------------------
>
> Key: KARAF-5210
> URL: https://issues.apache.org/jira/browse/KARAF-5210
> Project: Karaf
> Issue Type: Bug
> Affects Versions: 4.1.1
> Environment: Windows
> Reporter: Peter Berkman
> Assignee: Guillaume Nodet
> Fix For: 4.2.0, 4.1.5
>
> Attachments: mvnsettings.xml, org.ops4j.pax.url.mvn.cfg
>
>
> We have an installer that automates much of our Karaf and product
> installation.
> since the upgrade to Karaf 4.1, I've been getting these about every 5th
> automated install. could be timing? Happens at random places and sometimes
> with dependencies that the target doesn't have.
> One thing is that we do turn OFF internet access for maven through settings
> in the org.ops4j.pax.url.mvn.cfg and provider our out mvnsettings.xml. I
> will try and attach them later, but these are the relevant settings:
> {code}
> org.ops4j.pax.url.mvn.settings=${karaf.etc}/mvnsettings.xml
> org.ops4j.pax.url.mvn.localRepository=${karaf.data}/repo
> org.ops4j.pax.url.mvn.useFallbackRepositories=false
> org.ops4j.pax.url.mvn.defaultRepositories=
> org.ops4j.pax.url.mvn.defaultLocalRepoAsRemote=true
> org.ops4j.pax.url.mvn.repositories= \
>
> file:${karaf.home}/${karaf.default.repository}@id=system.repository@snapshots,\
> file:${karaf.data}/kar@id=kar.repository@multi@snapshots
> {code}
> mvnsettings.xml:
> {code}
> <settings xmlns="http://maven.apache.org/SETTINGS/1.1.0";
> xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
> xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.1.0
> http://maven.apache.org/xsd/settings-1.1.0.xsd";>
> <localRepository>data/repo</localRepository>
> </settings>
> {code}
> Here is what the stack looks like - note that the target bundle is almost
> always different on different failures.
