David Jencks updated KARAF-910:
-------------------------------
Attachment: KARAF-910-ops4j-2.diff
Again, for ops4j.
This version depends on a flag in framework properties
org.ops4j.pax.url.mvn.require.config.admin.config
If present, it waits for a config admin based configuration (that should not
include this flag). So including this flag in framework properties should
prevent the mvn url handler from registering until the config admin config
shows up.
The other url handlers don't check for validity so they will work with
framework property configuration as they do now.
Another difference is that to make this work you need to avoid fallback
configuration. Either you use config admin config or framework property config
but you can't mix them. Otherwise the flag will always be seen and prevent any
configuration at all.
> Race between FeatureService and ConfigAdmin for resolving mvn: URLs?

> I have an intermittent problem where my custom features.xml cannot be
> resolved. I use a tweaked etc/org.ops4j.pax.url.mvn.cfg file so the
> features.xml file is never present in $HOME/.m2/repo but is instead is
> resolved to local repo relative to the app:
> org.ops4j.pax.url.mvn.defaultRepositories=file:${karaf.base}/system@snapshots,\
> file:${karaf.home}/${karaf.default.repository}@snapshots,\
> file:${karaf.base}/../../../.env/.m2/repo@snapshots
> Sometimes when I start Karaf, I get this error (actual URL edited for privacy)

> specified in etc/org.ops4j.pax.url.mvn.cfg.
> I interpret that to mean that sometimes the features resolution happens
> before Felix reads the files in etc/ and sometimes the features load
> afterward. Mostly I'm using the same startlevels as Karaf -- my
> startup.properties file is identical to the following except for a few
> additions I made.
