Please help! T_T

That doesn't work. When I try to clean up the cache and setupDevWorkspace. Sorry!

Exactly the same problem on my machine. (forge-1.8-11.14.0.1268-1.8-src.zip)

Also something very similar happens when you just want to acquire some information via reflection (see

[1.8] ClassFormatError when loading class "net/minecraft/client/gui/GuiScreen")

Something in your setup is non-standard.

And it is causing the exception information to be injected incorrectly.

A clean cache, and updated FG should work just fine.

If not you need to provide your exact setup

I tried running Minecraft Forge (in eclipse) again, on my old Windows XP computer this time, but with exactly the same result.

Environment:

• Operating System: Windows XP 32bit
  
• Java: jdk-7u71-windows-i586
  
• Eclipse: Version 3.4.2
  
• ForgeGradle: forge-1.8-11.14.0.1268-1.8-src
  

Out of curiosity, what are the exact versions of the java runtime environments Minecraft Forge (in eclipse) is known to start up correctly.

I tried to run Minecraft Forge with the latest version of everything, but the error still occurs.

Environment:

• Operating System: Windows 7 Professional SP1 64bit
  
• Java JDK: jdk1.8.0_25 (64bit) (JAVA_HOME)
  
• Java JRE: jre1.8.0_25 (64bit)
  
• Eclipse: IDE for Java Developers - Luna Service Release 1 (4.4.1)
  
• ForgeGradle: forge-1.8-11.14.0.1269-1.8-src
  

Procedure:

• Delete folder "/AppData/.gradle"
  
• Ensure JAVA_HOME is "C:\Program Files\Java\jdk1.8.0_25"[/i]
  
• Unpack forge-1.8-11.14.0.1269-1.8-src.zip
  
• Open Command promt in folder "forge-1.8-11.14.0.1269-1.8-src"
  
• Execute "gradlew setupDevWorkspace"
  
• Execute "gradlew eclipse"
  
• Run eclipse
  
• Switch workspace to "forge-1.8-11.14.0.1269-1.8-src\eclipse"
  
• Select Run/Client
  
• Error above shows up in eclipse console
  

give me your entire .gradle folder and your project folder.

SOMETHING is adding invalid exceptions to the classes, and it is not our data.

I am also providing the console stdout from the gradlew executions.

Artefacts:

• Folder ".gradle": gradle.zip
  
• Project folder: project.zip
  
• Stdout "gradlew setupDevWorkspace": gradlew_setupDevWorkspace_stdout.txt
  
• Stdout "gradlew eclipse": gradlew_eclipse_stdout.txt

That should fix it, refresh everything and run again, thats really really odd.

Guess we found a 'bug' in Fernflower, it shouldn't decompile those classes correctly.

Confirmed - after a full refresh and rebuild the client started up normally in eclipse.

Thank you very much. That's work!
