Kolada increases the compatibility of Forge with the Kotlin™ programming language. It provides a language loader with custom annotations and bundles commonly used Kotlin libraries in its mod-jar. Kolada works with MC version 1.14.4.
This mod bundles the Kotlin Standard Library, Kotlin Reflection, Kotlinx Coroutines Core and the Kotlinx Serialization Runtime.
Information for developers is available on GitHub.
For MC version 1.8.4 or below refer to Shadowfacts' Forgelin which is similar to Kolada in its function.
