Can't run Forge 1.6.1 from within eclipse

Hello!

I'm trying to run forge from within eclipse and everytime I'm getting this error

Exception in thread "main" java.lang.NullPointerException

at java.util.logging.Logger.setParent(Logger.java:1472)

at net.minecraft.logging.LogAgent.setupLogger(LogAgent.java:33)

at net.minecraft.client.main.Main.main(Main.java:77)

at Start.main(Start.java:68)

I don't use the eclipse workspace given in MCP instead I have my own with the following setup:

my eclipse enviroment in the Java Build Path

Source folder pointing at minecraft

jars folder is linked to the project but not set as source

Libraries and all of the jars from the jars/libraries folder are all added to the project and selected in the Order and Export tab

jars/version/1.6.1/1.6.1.jar is also added and selected

Native library location set for lwjgl* and jinput pointing at forge161/jars/versions/1.6.1/1.6.1-natives

My run configuration is

Main class: Start

Working Directory: ${workspace_loc:forge161/jars}

No arguments

All of source is compiled correctly in eclipse with 0 errors but with a lot of warnings.

I tried this exact same setup for running decompiled minecraft 1.6.1 with MCP but without forge and it runs fine.

I also used to use this setup to run forge for 1.5.2 with no problems

I tried running it from forge/mcp/startclient.bat and that is not working either, it's giving the same error:

I can't run the Minecraft forge server either:

For the server I added the jars/minecraft_server.1.6.1.jar to the Library and selected for export

The run configuration for the server is:

Main class: net.minecraft.server.MinecraftServer

The error is:

Exception in thread "main" java.lang.ExceptionInInitializerError

... 4 more

the mcp/startserver.bat is also giving an error, but it has more to do for not adding the launchwrapper-1.3.jar to the classpath

any ideas?

I am having the EXACT same problem, so I will bump you

Turns out this is an FML issue.

configureLogging in FMLRelaunchLog is never called so the Logger isn't properly initialized before it's called in Minecraft.java

I just have no idea how everybody else seems to be running forge and modding, it's virtually impossible at the moment since the cpw package is missing some functionality. but what the hell do I know.

I'll wait

Actually its not a FML issue.

Its a launch configuration issue. We ship those for a reason u.u

You need to launch the legacylauncher.Launch class

Not Start.main

Thank YOU!!! SO MUCH!

I really felt i was out of the loop!

I did try the net.minecraft.launchwrapper.Launch at some point but that gave me an error, didn't know the arguments. so i dismissed it.

Thank you for pointing me to that file, I would have never guessed.

Main Class:

net.minecraft.launchwrapper.Launch

Program arguments:

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

But trying to run the Server still gives the error I mentioned above

I checked the Server.launch and it's the same as mine, no arguments and calling net.minecraft.server.MinecraftServer. any ideas on that one?

https://github.com/MinecraftForge/FML/blob/master/install/eclipse/.metadata/.plugins/org.eclipse.debug.core/.launches/Server.launch

Ya, cpw forgot to update that.

You need to call ServerLaunchWrapper cant remember the exact name right now.

Once again thanks!!

Main class:

cpw.mods.fml.relauncher.ServerLaunchWrapper
