Ethan's Kotlin Extensions 2.1-neoforge targets 26.1, 26.1.1, 26.1.2 with NeoForge. Installation on the client is optional. Installation on the dedicated server is optional. All 1 required mods have matching files.
Where it goes
Is Ethan's Kotlin Extensions required on the client, server, or both?
Installation on the client is optional. Installation on the dedicated server is optional.
The source marks this as usable on both the client and server.
What else does Ethan's Kotlin Extensions 2.1-neoforge need?
2.1-neoforge. Change the file and its required mods may change too.
Install KotlinLangForge first. We found matching files for this game-version and loader setup.
We only count dependency files that match this setup. A file for another loader does not fill the gap.

About this project
What does Ethan's Kotlin Extensions add?
This mod includes additional Kotlin libraries to use alongside Fabric Language Kotlin or KotlinLangForge.
Libraries currently added:
- Kotlin Scripting JVM
- Kotlin Scripting JVM Host
- Kotlin Scripting JSR223
- Kotlin Scripting Dependencies Maven
- Kotlin Compiler
- Tiny Remapper (Only supplied before Minecraft 26.1)
- Mapping IO (Only before Minecraft 26.1)
- Kotlin Metadata JVM
The list of libraries may grow in the future.
Just like Fabric Language Kotlin, any mods depending on this must NOT include/embed the mod, especially since the Kotlin compiler is included in this mod, which makes up for such a large file size.
