Hi, I'm really excited to see the new starters for bootstrapping, if I can give you a hand on the PoC I will be pleased to help.
+1 for the karaf-boot-maven-plugin with @bootstrap annotation way. I also think it's a good idea to build the new guide on karaf-boot, so it's possible to refer to a working example. Regards, Morgan PS: I don't see my samples, should I propose them as PRs? 2016-05-11 17:04 GMT+02:00 Jean-Baptiste Onofré <j...@nanthrax.net>: > Hi all, > > Karaf Boot code is now on the Apache Git: > > https://git.apache.org/karaf-boot.git/ > > with the github mirror: > > https://github.com/apache/karaf-boot > > I created the component in Jira. > > I will update the website with karaf-boot description. > > I propose the following roadmap for karaf-boot, heading to the first 1.0 > release: > > 1.
