Karaf auto polling for latest version

Question

I am a new bee in the world of OSGi and using Apache Karaf for my application. I know how to create/work with bundle and features. I have my A.jar, which I have deployed in karaf_home/deploy folder and its working.

My actual requirement is, I will update the jar version in our Maven repo and I want Karaf automatically poll that external repository for any updated version. If it finds any updated version is present, it will download and install it.

If I can put the latest version (by some means) under karaf_home/deploy directory, Karaf consumes it automatically and working fine. I want to automate this download process from some external path (may be maven repo as mentioned earlier). Is it possible at this level?

Thanks in advance

Answer 1

You can do this for a local repository and only for snapshot versions. Just type dev:watch * in the karaf shell.

Then karaf will monitor the local maven repo for all artifacts currently deployed using the mvn: protocoll and that end in -SNAPSHOT for the version. If you then do mvn install on such a project karaf will automatically update the bundle.
