While there seem to be a couple of projects that use Eclipse as a framework to deploy applications, there are very little that use actual target platforms for some reason. Most want you to download and install a custom Eclipse just to deploy a specific snapshot of their application (example: DBeaver).
I personally want to have a nice, reproducable build that uses the same code in my IDE as while packaging JARs, so I created an example application using a target platform file: example-eclipse-application
I even managed to use plain Maven dependencies (even if they’re not OSGi bundles) in that reactor!
(This showed a couple of bugs with the Random and Charts Frameworks, but I guess that’s life. ¯\_(ツ)_/¯)
