Hello everyone

 

I just setup my development environment with a new version of Forge (789) and added all the Libraries from mcp/jar/libraries to my classpath and set the source folder to be mcp/src/minecraft. So when I launch Minecraft with the Start.java class I get the following NullPointer Exception:

Exception in thread "main" java.lang.NullPointerException
at java.util.logging.Logger.setParent(Logger.java:1406)
at net.minecraft.logging.LogAgent.setupLogger(LogAgent.java:33)
at net.minecraft.logging.LogAgent.<init>(LogAgent.java:25)
at net.minecraft.client.Minecraft.<init>(Minecraft.java:308)
at net.minecraft.client.main.Main.main(Main.java:77)
at Start.main(Start.java:68)

I have no clue, how I could fix that, because I didn't touch the source directory yet, it is like forges install.bat left it.

BTW: I work with IntelliJ IDEA, but I don't think that matters

 

I thank you in advance

You need to use the Launcher class as the main method now not Start class. Afaik it's needed to proxy the new minecraft loader

Thank you for your answer, but unfortunately this gives me another error:

Jul 11, 2013 2:17:53 PM net.minecraft.launchwrapper.LogWrapper log
INFO: Using tweak class name net.minecraft.launchwrapper.VanillaTweaker
Jul 11, 2013 2:17:54 PM net.minecraft.launchwrapper.LogWrapper log
SEVERE: Unable to launch

at java.lang.Class.getMethod(Class.java:1622)
at net.minecraft.launchwrapper.Launch.launch(Launch.java:54)
at net.minecraft.launchwrapper.Launch.main(Launch.java:18)

When i look in the Minecraft class, i can't see a main method, should there be one?

You should launch with net.minecraft.launchwrapper.Launch.

That's what I was doing. But I got the error I posted above.

The error is just, that there is no main method in net.minecraft.client.Minecraft, so obviously this gets called by the net.minecraft.launchwrapper.Launch class, but doesn't exist.

Do you have the program arguments

--version 1.6 --tweakClass cpw.mods.fml.common.launcher.FMLTweaker

OK thank you works now like a charm.
