This will cause Gradle to throw a selection error when for example paper-api and spigot-api are on the classpath. Users will need to add selection rules or excludes for certain transitive deps to solve this rather than build with a broken classpath.
SLF4J is a commonly used abstraction for various logging frameworks
such as java.util.logging (JUL) or Log4j. Currently, plugins are
required to do all their logging using the provided JUL logger.
This is annoying for plugins that target multiple platforms or when
using libraries that log messages using SLF4J.
Expose SLF4J as optional logging API for plugins, so they can use
it without having to shade it in the plugin and going through
several layers of logging abstraction.
The pom.xml file is deleted in this patch so the patch will fail to
apply if there are changes made to it from upstream - thus notifying us
that changes were made.
