I need help to use or to install MCP on Eclipse with no erorrs. I've got CMS Erorr with my Java 64-bit Server. I want to make mods for Minecraft Forge 1.7.10. I need a Forge client.jar.
If you want to make a mod for Minecraft, you want to be using Forge. Follow the tutorial here. If it doesn't work, come back with any error messages you're getting.
