I've made a 1.6.4 Vanilla server, and added McForge, everything works fine when I start the server, but after adding mods or a mod, the server crashes. Here's the Crash report log. ---- Minecraft Crash Report ---- // I just don't know what went wrong Time: 10/14/13 3:52 PM Description: Exception in server tick loop java.lang.NoClassDefFoundError: net/minecraft/client/entity/EntityClientPlayerMP at TMIForgeContainer.tickStart(TMIForgeContainer.java:84) at cpw.mods.fml.common.SingleIntervalHandler.tickStart(SingleIntervalHandler.java:28) at cpw.mods.fml.common.FMLCommonHandler.tickStart(FMLCommonHandler.java:122) at cpw.mods.fml.common.FMLCommonHandler.onPreWorldTick(FMLCommonHandler.java:295) at net.minecraft.server.MinecraftServer.func_71190_q(MinecraftServer.java:652) at net.minecraft.server.dedicated.DedicatedServer.func_71190_q(DedicatedServer.java:276) at net.minecraft.server.MinecraftServer.func_71217_p(MinecraftServer.java:587) at net.minecraft.server.MinecraftServer.run(MinecraftServer.java:484) at net.minecraft.server.ThreadMinecraftServer.run(SourceFile:583) Caused by: java.lang.ClassNotFoundException: net.minecraft.client.entity.EntityClientPlayerMP at net.minecraft.launchwrapper.LaunchClassLoader.findClass(LaunchClassLoader.java:186) at java.lang.ClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) ... 9 more Caused by: java.lang.NullPointerException at net.minecraft.launchwrapper.LaunchClassLoader.findClass(LaunchClassLoader.java:178) ... 11 more A detailed walkthrough of the error, its code path and all known details is as follows: --------------------------------------------------------------------------------------- -- System Details -- Details: Minecraft Version: 1.6.4 Operating System: Windows 7 (x86) version 6.1 Java Version: 1.7.0_25, Oracle Corporation Java VM Version: Java HotSpot Client VM (mixed mode, sharing), Oracle Corporation Memory: 141723240 bytes (135 MB) / 254001152 bytes (242 MB) up to 259522560 bytes (247 MB) JVM Flags: 0 total; AABB Pool Size: 0 (0 bytes; 0 MB) allocated, 0 (0 bytes; 0 MB) used Suspicious classes: FML and Forge are installed IntCache: cache: 0, tcache: 0, allocated: 3, tallocated: 63 FML: MCP v8.11 FML v6.4.20.916 Minecraft Forge 9.11.1.916 5 mods loaded, 5 mods active mcp{8.09} [Minecraft Coder Pack] (minecraft.jar) Unloaded->Constructed->Pre-initialized->Initialized->Post-initialized->Available->Available->Available->Available FML{6.4.20.916} [Forge Mod Loader] (minecraftforge-universal-1.6.4-9.11.1.916.jar) Unloaded->Constructed->Pre-initialized->Initialized->Post-initialized->Available->Available->Available->Available Forge{9.11.1.916} [Minecraft Forge] (minecraftforge-universal-1.6.4-9.11.1.916.jar) Unloaded->Constructed->Pre-initialized->Initialized->Post-initialized->Available->Available->Available->Available TooManyItems{1.6.4} [TooManyItems] (minecraft.jar) Unloaded->Constructed->Pre-initialized->Initialized->Post-initialized->Available->Available->Available->Available AnimationAPI{1.1.1} [AnimationAPI] (AnimationAPI v1.1.2 mc1.6.4.zip) Unloaded->Constructed->Pre-initialized->Initialized->Post-initialized->Available->Available->Available->Available Profiler Position: N/A (disabled) Vec3 Pool Size: 0 (0 bytes; 0 MB) allocated, 0 (0 bytes; 0 MB) used Player Count: 0 / 20; [] Is Modded: Definitely; Server brand changed to 'fml,forge' Type: Dedicated Server (map_server.txt)
