Every time I try to launch Minecraft 1.8 with Forge from Eclipse, I get the following error:

In order to fix this problem, I have uninstalled and installed several different versions of Jre and Jdk (none of which were Java 8 ). Didn't work. I have not yet tried replacing the Light Weight Java Game Library included in the Forge download with a newer version. You would think, however, that Forge would come with a working version of lwjgl. Any help?

 

My Currently Installed Version of Java: Java 7 update 72

 

My Eclipse run Configurations

-----------------------------------------

Main Class: net.minecraft.launchwrapper.Launch

 

Program Arguments: --version 1.8 --tweakClass net.minecraftforge.fml.common.launcher.FMLTweaker --accessToken modstest --userProperties {} -username=Honeydew --assetsDir=eclipse/assets

 

VM Arguments: -Dfml.ignoreInvalidMinecraftCertificates=true

Note: I have tried changing "--version 1.8" to "--version 1.7." Again, didn't work. I only tried this on 7 u72, though. not u71.

Use GradleStart as your main class.

 

Ah! Thank you. That worked.
