Question Conflicting jackson-databind versions starting in 1.21.3

[CrazyCranberry]

Hello!

My mini-golf plugin serializes and deserializes yaml for course information. I'm using the com.fasterxml.jackson.dataformat.jackson-dataformat-yaml dependency to do so. My plugin stopped working with the release of paper 1.21.3; methods from within my dependencies were missing. I'm understanding the issues to be a result of conflicting jackson-databind versions (jackson-databind is a dependency of jackson-dataformat-yaml). My plugin is currently using jackson-dataformat-yaml version 2.16.1 but it looks like paper is using a version of jackson-databind-2.13.4.2. If I lower my version of jackson-dataformat-yaml to 2.13.4 (there is no 2.13.4.2) I then get a similar error about snakeyaml.

This may be a straight java question, but how can I force my plugin to use the version of dependencies I declare in my pom.xml?

I'm having this issue on spigot too So disregard. Sorry!

 

[LoJoSho]

You should just be able to shade the dependency, and then relocate it within your jar. That way, your plugin will not get confused with other dependencies that are there.

Mojang ships an older version, if you want a newer one you need to relocate it.

I'm having the same issue. Is it possible to fix it without shading the dependency? I'm using a PluginLoader to load the libraries.
