I've always used File > Import > Install > From Existing Installation to bring over plugins from old Eclipse releases. However, in Neon, it doesn't work when I select my Luna directory.
I used this process:
- mv eclipse eclipse.luna
- Unzip Neon jee package
- edit eclipse/eclipse.ini as needed
- Start Neon
- File > Import > Install > From Existing Installation
- Next
- Browse to Luna directory
- OK
Error message says "Select at least one available element to be installed". There are no items listed in the list box area.
Is this a known issue in Neon? I don't see any relevant errors in eclipse-workspace/.metadata/.log
