Question

I am working on a fix for a mod for the game minecraft. but there is a catch. The mod is not made by me, so i have to decompile it

To make a long story short, this is my first time working on obsfucated, noncomplete sources.

I am only gonna edit ONE file (out of around 1.5K).

It decompiled fine, and i edited what i wanted, but now i can’t compile it. I am using the classpath variable to point it to the jar, so i can still use the classes from the rest of the game. but 2 errors exists, both involving “.getDeclaredField(s)”.

Code:

public static Minecraft getMinecraft()
{
    try
    {
        Field field = Minecraft.getDeclaredField("a"); // Error here
        field.setAccessible(true);
        return (Minecraft)field.get(null);
    }
    catch(IllegalAccessException illegalaccessexception)
    {
        illegalaccessexception.printStackTrace();
    }
    catch(NoSuchFieldException nosuchfieldexception)
    {
        nosuchfieldexception.printStackTrace();
    }
    return null;
}

The other case is just like this, so no need to show you that.

Error log:

TMIUtils.java:23: cannot find symbol
symbol  : method getDeclaredField(java.lang.String)
location: class net.minecraft.client.Minecraft
Field field = Minecraft.getDeclaredField("a");

How will i go about fixing this? (keep in mind this is the first time working with getDeclaredField too)

Answer 1

It should be

Minecraft.class.getDeclaredField("a");

Perhaps it’s a decompiler’s error.

getDeclaredField() is a method of type Class, and Minecraft.class is a literal value of that type.
