Here we have a YAML mapping the old Minecraft IDs (97, 97:1, etc.) to the newer Spigot Material Enum Constants. Both values (IDs to Enum Constants) are String values in the YAML file. I made this while updating an old plugin, because the config used the old Minecraft IDs and I thought it would be convenient to be able to use both IDs and Material Enum Constants. This is something that you could stick in the jar as a resource and use JavaPlugin.getResource() to read from it, this way plugin users can't inadvertently break anything Here's the Gist: https://gist.github.com/ryanopily/c4aa83f87f32db796cb4041db1015e2a I know there's probably not many people who would use this, but I thought I'd share it just in case. It's not a perfect list I'm sure, but it works.
