I'm thinking about writing an OSGi plugin for karaf that can be
configured to watch a remote repository for snapshot updates.
The idea is to do something like this
1. For each configured bundle, if the bundle has a snapshot version, intially
do
a. Get the maven coordinates
b. Scan the configured repositories and chose the first repository
that has the artifact
c. Download the Repo-URL/groupId/artifactId/version/maven-metadata.xml
and parse it to find the most recent snapshot, taking note of the
maven repository, newest snapshot version, newest snapshot
timestamp, as well as the update time of the maven-metadata.xml
file
2. Schedule a job that for each configured bundle, that:
a. Does a conditional GET for the
Repo-URL/groupId/artifactId/version/maven-metadata.xml
file
b. If the conditional GET receives content, parse the content and
extract the snapshot version and timestamp and compare them with
the save versions to see if they actually have changed
c. If a new snapshot has arrived, tell the bundle to update
Right now I'm reading the Pax-URL documentation[1] trying to figure out
if it's possible to do step 1b.
Does anyone familiar with Pax-Url think this might be feasible? Or is
the actual repo used so hidden away that it is hard to do?
Thanks!
