Hi @Shiki_Rahnclave, would you be able to share the current status of what you had achieved? I know it didn't work fully, but at least it would not be lost. And in case you remember what the remaining problem(s) was, please document it here.

References #386: Adds Maven & Tycho configurations and poms.

Uses pomless setup right now which uses the plugin dependencies from the MANIFEST.MF.

Does not directly reference core requiring it to be built in advance.

For now, the recommended structure with plugins/ and tests/ is not used.
