ChangeSkinX
Description
This plugin allows your players to change their skins by command. These skins have to be downloaded from Mojang, because Minecraft clients only accept from Mojang signed skins. But you can choose every skin that another minecraft user currently has.
Moreover it will be possible to set a custom standard skin. If you want to, this plugin can set this standard skin for all players who still have the default steve or alex skin.
Features
- Lightweight
- Instant skin updates
- Easy to use
- Implemented cache to benefit performance
- Nearly no mojang rate limits due caching
- No client modification needed
- Possibility to create a standard skin
Commands
- /setskin <uuid > - Sets your skin to be equal to the player with the selected uuid
- /setskin < playerName>
- /setskin < onlinePlayer > < newSkinUUID/newSkinPlayerName >
- /skinupdate - Invalidates the database entry and fetches the fresh skin from the Mojang servers
Permissions
- changeskin.command.skinupdate - Command to refresh the own skin
- changeskin.command.setskin.* - All the commands below
- changeskin.command.setskin - Set your own skin
- changeskin.command.setskin.other - Set the skin of other players
Whitelist and blacklist permissions
Whitelist
- changeskin.skin.whitelist.uuid - Allow this specific skin
- changeskin.skin.whitelist.* - allows all skins
Blacklist
- changeskin.skin.whitelist.*
- -changeskin.skin.whitelist.uuid
Source code
You don't have to decompile the plugin. You can find there the source code with comments and building utilities.
ChangeSkin is open source and hosted on GitHub; feel free to fork, star, or contribute by making pull requests and opening issues.

It's an error in ProtocolLib. Check out their project. Make sure you are using the correct version. The latest development version of ProtocolLib for example is not backwards compatible.

Click on the GitHub page. There is a section about developments. They are basically version in between releases. The error you posted is not complete, so I cannot help you with that.

Ah there it is:
NoClassDefFoundError: com/comphenix/protocol/utility/MinecraftVersion
It means the plugin expected a certain file to be existing, but it wasn't there. In this case you need to update ProtocolLib. This version you are using is out of date.

ProtocolLib dropped support for older Minecraft versions. At the top of their page says: 4.8 for versions between 1.8.8 and 1.18 and 5.0 only for 1.19 and up. After a certain time it was too hard to keep backwards compatibility.

Sorry I was sick last week, but I fixed your bug yesterday. For 1.19, you should be able to download a newer development build of ChangeSkin and that should then work with ProtocolLib 5.0. Both versions are necessary for 1.19.

No, it will fail safely to false as a safe value. Chat validation error could be related to another system. The error is about the new chat reporting feature. It could be another plugin modifying chat messages. Could you check that? There is also the possible to disable chat message verification by toggling the secure profile in the server.properties, but then you loose the ability to report player profiles.
