the recommended approach to deploy any kind of artefact (jar, war, bundle etc) into fabric8 / jboss-fuse is via the maven plugin:
https://github.com/fabric8io/fabric8/blob/master/docs/mavenPlugin.md

so the build does a "mvn fabric8:deploy" in the maven project. There's a few maven properties available that can be used to configure the profile that gets lazily created/updated too.

It'd be great to have good integration in eclipse for using this mechanism. Note that the code is fairy simple - it'd be easy to replicate the functionality natively in eclipse itself too without the maven part; though its maybe easier to just use the maven plugin?

e.g. https://github.com/jstrachan/fabric8/blob/micro-service/fabric/fabric8-maven-plugin/src/main/java/io/fabric8/maven/DeployToProfileMojo.java#L124-124

the main issue is going to be specifying a maven ~/.m2/settings.xml which has the login/pwd to connect to fabric. Though the current deploy mechanism in Fuse IDE uses a similar approach to be able to deploy into the fabric via maven
