How can I add a processor/language to the full Ghidra codebase in Eclipse (not in a GhidraDev extension)?

Not a Java guy. Still puzzled by Eclipse, build system, etc. regularly.

I thought I might delve into the inner workings of the sleigh system to help me understand it, especially when it fails without errors that guide me while I work on my first processor definition.

This is intuitive to do in a GhidraDev project via the Package Explorer, which is hierarchical:

I do not find it intuitive in the full Ghidra project however where in the Project Explorer each Processor is its own entry in the big flat list, even if I turn on the hierarchical option:

Simply naïvely copying the directory structure over doesn't make it appear in the project no matter how I try to refresh, clean, or rebuild it.

After you copy it, you need to do a gradle eclipse and then File -> Import -> Existing Projects into Workspace. We rely on Gradle to generate the Eclipse projects.
