Compiling Eaglercraft with support for EFI

In recent updates of eaglercraft, compiling for EaglerForgeInjector has become a great deal more complicated. To enable reflection and disable obfuscation, follow these steps once you have an EaglercraftX workspace set up:

1. In any files named build.gradle, set the obfuscate property to false.
2. In any files named build.gradle, find any code that looks like this:

   tasks.named("generateJavaScript") {
       doLast {
   
           // NOTE: This step may break at any time, and is not required for 99% of browsers
   
           def phile = file(folder + "/" + name)
           def dest = phile.getText("UTF-8")
           def i = dest.substring(0, dest.indexOf("=\$rt_globals.Symbol('jsoClass');")).lastIndexOf("let ")
           dest = dest.substring(0, i) + "var" + dest.substring(i + 3)
           def j = dest.indexOf("function(\$rt_globals,\$rt_exports){")
           dest = dest.substring(0, j + 34) + "\n" + file(folder + "/ES6ShimScript.txt").getText("UTF-8") + "\n" + dest.substring(j + 34)
           phile.write(dest, "UTF-8")
       }
   }
   

   and delete it.
3. Inside of the src/teavm/java/net/lax1dude/eaglercraft/v1_8/internal/teavm/ folder, create a new file called ForceReflection.java, with these contents:

   package net.lax1dude.eaglercraft.v1_8.internal.teavm;
   
   public class ForceReflection {
       public static Object myObject;
   
       public static Object forceInit(Class iClass) {
           myObject = new ReflectiveClass();
           try {
               myObject = iClass.newInstance();
           } catch (Exception e) {
               // TODO: handle exception
           }
           return myObject;
       }
   
       public static class ReflectiveClass {
       }
   }
   

4. In the same folder, edit MainClass.java edit the start of the main(String[] args) method to look like this:

   public static void main(String[] args) {
   	ForceReflection.forceInit(ForceReflection.class);
   	if(args.length == 1) {
       //... rest of method
   

5. Finally, build an offline download by using CompileJS.bat/CompileJS.sh and then MakeOfflineDownload.bat/MakeOfflineDownload.sh.
6. You can then upload the EaglercraftX_1.8_Offline_en_US.html into EaglerForgeInjector.
