In Kotlin 1.7.0, we’ve reworked incremental compilation for project changes in cross-module dependencies. The new approach lifts previous limitations on incremental compilation. It’s now supported when changes are made inside dependent non-Kotlin modules, and it is compatible with the Gradle build cache. Support for compilation avoidance has also been improved. All of these advancements decrease the number of necessary full-module and file recompilations, making the overall compilation time faster.
