Have you built the plugin yourself, or are you using a version downloaded from Modrinth?

To elaborate on that, ServerPlayer is a Mojang mapped name, while EntityPlayer is the spigot mapping for the same class.

[Hephaisto-dev]

I build it myself yes

[e-im]

Okay. You need to use the reobfJar gradle task (so ./gradlew reobfJar), and grab the artifact that does NOT end in -dev.

Let me know if this works for you.

[Hephaisto-dev]

Actually i use maven with a remapped spigot as a dependency maybe that is the problem

[e-im]

uh yeah, that will definitely not work. The plugin is developed using Mojang mappings and remapped to spigot at build time.

[Hephaisto-dev]

Can i use direcly spigot mapping or it's harder?

[e-im]

What is your actual goal here?

You can manually change all the instances where a mojang-mapped name is imported or used to spigot mappings— or even use some source remapping tool, but the plugin is very small, so there are only a few instances.

Hmm.. i see.
Well i think i will find a way to remap with maven, good to know for the future.
Thanks for the tips.
