This is not just about Gradle, and not related to the build cache. There are different things: mixing Java and Groovy sources in a single source tree **only** makes sense for sources which are _joint compiled_. Otherwise you're just slowing down your build arbitrarily, because Groovy has to generate stubs for all Java classes just in case they would be used by Groovy sources. The intuitive part to me is that Groovy sources should live in `src/main/groovy`, the Java sources in `src/main/java`, and that joint sources should be in another directory (we don't do this). Then it's also about performance: it means we can use incremental Java compilation, and soon Groovy incremental compilation too. So this is not just about what a human would think, this is just about good separation of concerns, and software architecture in general.
