I recently bought the book "minecraft mods programming absolute beginners guide" To make import a mod into minecraft the book said to make a local host server with 1.7.10 bukkit. When I ran the server I got this : C:\Users\martial\Desktop\server>java -Xms1024M -Xmx1024M -Xmx1024M -jar bukkitse rver.jar Loading libraries, please wait... [12:59:50 INFO]: Starting minecraft server version 1.7.10 [12:59:50 INFO]: Loading properties [12:59:50 INFO]: Default game type: SURVIVAL [12:59:50 INFO]: Generating keypair [12:59:51 INFO]: Starting Minecraft server on *:25565 [12:59:51 INFO]: This server is running CraftBukkit version git-Bukkit-1.7.9-R0. 2-24-g07d4558-b3116jnks (MC: 1.7.10) (Implementing API version 1.7.10-R0.1-SNAPS HOT) [12:59:52 INFO]: Preparing level "world" [12:59:52 INFO]: Preparing start region for level 0 (Seed: -8493107121436534824) [12:59:52 WARN]: Could not get information about this CraftBukkit version; perha ps you are running a custom one?: FileNotFoundException [12:59:53 INFO]: Preparing spawn area: 12% [12:59:53 WARN]: Could not get latest artifact information: FileNotFoundExceptio n [12:59:54 INFO]: Preparing spawn area: 75% [12:59:54 INFO]: Preparing start region for level 1 (Seed: -4422384065147295339) [12:59:55 INFO]: Preparing spawn area: 47% [12:59:56 INFO]: Preparing spawn area: 80% [12:59:57 INFO]: Preparing start region for level 2 (Seed: -4422384065147295339) [12:59:58 INFO]: Server permissions file permissions.yml is empty, ignoring it [12:59:58 INFO]: Done (5.990s)! For help, type "help" or "?" Is there an alternative to importing mods to minecraft? IM fine with importing them through singleplayer. Im also using net bean. If someone could tell me how to import them through singleplayer that would be nice or how to fix the Could not get latest artifact information: FileNotFoundException and the Could not get information about this CraftBukkit version; perha ps you are running a custom one?: FileNotFoundException also im not trying to make a tekkit server just a regular 1.7.10 server to test mods on.
