So good news! Looks like I was able to get MineCraft to work with 1.8 using the default minecraft_server.jar file.
This most likely translates to a performance hit - but I wont' know by how much until I dig in further. The spigot.jar / bukkit.jar variations haven't caught up quite yet - with no real ETA for when they might be available. 1.8 now leverages a elua.txt file which must be manually set to "true" during install. This may be part of what is holding up spigot/bukkit development, but I'm un sure at this point.
In any case, I'm currently working on a new version to support 1.8. While performance may take a hit - It will now be compatible with the B+ model, so that's a plus.
I'll followup once the new image is live.
I spoke too soon.... the default minecraft_server.jar can't even run on the Pi, it's completely starved of resources. Just not possible.... So I guess we wait....
Apparently Spigot is fighting a legal battle after the MS takeover of Mohjang - You can read about it here: http://www.spigotmc.org/threads/our-dmc ... nse.28772/
It may be awhile before things get back on track....(if ever)
I'm really not sure what else I can do or try to get this working on the Pi once more... If you have suggestions - I'd be happy to hear from you...but right now - I've tried everything I can think of to revive MineCraftPi and I just can't seem to make it happen. Any ideas would be greatly appreciated!
