Failed to load mod

[1720693335]

Describe the bug
After successfully packaging the minecraftenv mod using build.gradle, placing it in the Minecraft client's mods folder results in a java.lang.ClassNotFoundException: kotlin.NoWhenBranchMatchedException error, preventing the mod from loading. This issue may be related to Kotlin.

Environment

• Minecraft Version: 1.21
• Fabric Loader: 0.15.11
• Fabric API: 0.100.6+1.21
• JDK Version: 21
• OS: Windows 11

Reproduction Steps

1. Clone the repository and navigate to the src/craftground/MinecraftEnv directory
2. Execute ./gradlew build (or shadowJar) to package the mod, generating a JAR file
3. Place the JAR in the Minecraft client's mods folder

Could you provide a more detailed, complete build process demonstration from source code to a runnable mod (including necessary configuration changes and commands)?
Thank you for your hard work and assistance! I really like your project.

Thank you for reporting this issue and your interest in CraftGround!

I need to clarify an important point: CraftGround is not a standalone Minecraft mod that you can directly place in your mods folder. Instead, it is a Python package that communicates with Minecraft through a mod backend.

Proper Installation & Usage

CraftGround should be installed and used as follows:

1. Install CraftGround via pip:

   pip install craftground

2. Use it in your Python code:

   from craftground import craftground
   env = craftground.make(port=8023, isWorldFlat=True, ...)

3. The mod component (MinecraftEnv) is automatically deployed when you create an environment through the Python API. You don't need to manually build or place the JAR file in the mods folder.

For detailed setup instructions, please refer to the Installation section in our README.

If you continue to experience issues after following the proper installation steps, please let us know!
