Looks like the DataExtractor no longer works with the latest Fabric API, it will likely need quite a large revamp. src/main/java/net/fabricmc/example/ExampleMod.java was moved to src/main/java/com/example/ExampleMod.java in the example repo as well. The first issue I came across while using the DataExtractor is that the World constructor has changed - there may be more.
