A simple tool that injects interfaces into a jar file. This is meant to be a build time tool to transform dependencies adding new interfaces. Allowing your code to compile against the injected code as if it was a normal dependency.
This uses the ClassFile API and so needs java 25+
java -jar facade.jar --input dependency.jar --output patched.jar --config interfaces.cfgCurrently there is no gradle demo/plugin for this, as the intended use is through ForgeGradle and Mavenzier.
Warning
There is no public API for this tool! This is designed to solely be a CLI tool, which means that all of the implementations are internal. We reserve the right to change the internal implementation at any time.
