  • Fixed AddonManager to process CoderAPI

    firesmasher forgot to update AddonManager to process CoderAPI

• Coder API Legacy Support:

  • Brought back me.coder.api.CoderAPI - Points to dev.codestuff.coder.api.CoderAPI

    added me.coder.api for older/not updated coder addons to work on version 2.4.2 or newer.

🛠 Features

• Native Multi-Language Support: Write and execute scripts in Java, Python, and Lua directly on your Minecraft server.
• Unified Workspace: Keep all your automation files organized in a single, dedicated folder.
• In-Memory Java Execution: Load Java code directly into server memory to keep active listeners and background processes running.
• Clean Cache Directory: Compiled .class files are cleanly separated:
  • Temporary runtime files: Coder/JavaClass/Runtime/
  • Loaded persistent files: Coder/JavaClass/Loaded/
• User Execution Control (UEC): An active security layer that intercepts unauthorized scripts. Regardless of the language used, nothing runs without UEC verification.
• Dual Backup Systems: Automated scheduled backups paired with instant manual snapshots.
• Graphical Web Interface (GWI): Securely manage, edit, and delete files on your server using a remote web browser window.
• Virtual Console Interface (VCI): Lets you securely run commands via https://coder-gwieditor.firesmasher.workers.dev/mc-console?=YOUR_TOKEN_HERE.
• Java 25 Support: Download the java-25 version of Coder.

🛡 GWI Editor Security

The remote GWI Editor is highly secure. Session connections leverage SHA-256 tokens which are mathematically impossible to brute-force or guess. Additionally, every session token automatically expires after 30 minutes of inactivity.

🛡 Virtual Console Interface Security

The custom minecraft console panel blocks /op commands and is secured by SHA-256 Server Password tokens, to disable this feature, you can go to /plugins/Coder/.gwi/secure/serverPassword.env and remove the value of serverPassword=.
