PluginManager fails to recognize paper-plugin.yml

[SlimeDog]

In order to test the new Paper paper-plugin.yml file, I manually added the following to my PluginVersions resource

$ cat paper-plugin.yml 
name: PluginVersions

When I restart the server, PluginVersions is loaded and enabled.

If I attempt to use PluginManager to unload and re-load the plugin, load fails.

[Lenni0451]

Paper plugins themselves are not supported yet. The latest release only fixes loading/unloading of bukkit plugins. I'm not sure if I will add full support for paper plugins in PM at this point of time because I am currently working on a recode (V3) because the old code is bad and I don't like it anymore. I will take a look anyways and see if it is worth adding to the old code...

[SlimeDog]

Speaking only for myself, targeting V3 is fine.

[SlimeDog]

V3 hasn't been touched in 4 months. Any estimate as to when it will be ready for testing?

[Lenni0451]

Tbh I've pretty much lost interest in spigot plugin coding. I'm not sure when or even if there will be any usable state of v3. But I might try picking it up again after this "break" I had for the last 4 months...
