Alright so, I have a plugin with the following libraries in plugin.yml
libraries: - org.flywaydb:flyway-core:10.11.1
NOTE: I removed libraries that i believe have nothing to do with this bug.
If you try to use flywaydb, You will get an error like this:

This error comes from the jackson annotations module. It looks like the server did not download or load it while resolving libraries on startup. However, doing this on a 1.20.4 server the plugin runs fine.
Adding "com.fasterxml.jackson.core:jackson-annotations:2.15.2" to plugin.yml fixes the issue as the library is downloaded and loaded. You aren't supposed to do that and it should be loaded normally as it is a transitive dependency.
This bug was not really tested much. Feel free to correct me if i misunderstand something. People from the discord server have directed me to create a bug report here.
