title: Modifying a .class file within a Minecraft mod
body: <p>I've used JD-Gui to decompile the <code>.class</code> files thanks to a suggestion I found on an unrelated question and I used Eclipse to edit the <code>.java</code> code.</p>
  
  <p>The issue comes when I recompile it into a <code>.class</code> file using the build function of Eclipse. Instead of creating a <code>.class</code> with all the code of the <code>.java</code> within it, it creates a <code>.class</code> that has replaced every function with an output stating what the error is. I thought when you told the compiler to compile with the errors it would use the code as is instead of replacing the code with the errors.</p>
  
  <p>All I want to do is modify the <code>.class</code> file and I can't seem to find a solution to my issue. Is there any way to actually compile the code as is instead of being replaced with the error that the code generates?</p>
