RaspberryJuice fails with Pokkit under Nukkit

[denisglotov]

RaspberryJuice v.1.11
Pokkit v.0.8.1
Nukkit v.1.0-SNAPSHOT

Looks the plugin does not work with modern version of nukkit. Please advise, if fixing is worth the effort? Or are there good alternatives?

$ java -jar nukkit-1.0-SNAPSHOT.jar

Outdated plugin. Pokkit does use 1.13.1 API and GOLD_SWORD is called LEGACY_GOLD_SWORD in it.

[denisglotov]

Latest snapshot Nukkit currently only supports API 1.0.9 (matching Minecraft BE clients 1.12 only). What do you mean as '1.13.1' and where could I see the API, please advice.

UPD: I see that 1.13.1-R0.1-SNAPSHOT is the dependency version of 'spigot-api' that Pocket uses. RaspberryJuice plugin uses 1.12.2-R0.1-SNAPSHOT of 'bukkit'. Do you think that upgrading the plugin to bukkit 1.13.1 helps (since spigot-api includes bukkit, if I got it right)?

Yes. Pokkit does use Bukkit/Spigot 1.13.1-R0.1-SNAPSHOT API. (Maybe going to bump that to 1.13.2) Updating your plugin to use that API will fix this. You can find 1.13 javadocs for example from here: https://papermc.io/javadocs/paper/1.13/overview-summary.html

BTW, I prepared a fix here zhuowei/RaspberryJuice#86.
