Question

Alright, I’m not very knowledgeable in Java, and I don’t even know if this is possible, but here I go anyway.
I have taken a .class file from a JAR and decompiled it. I have edited it to what I want, but now I want to recompile it. Is it possible to recompile that one .java file so I can then place it back inside the jar file? When I try to recompile it by setting the source path it says there is an error inside one of the .java files that my file references (is that the word for it?) even though there is not.

EDIT: The decompile WAS successful.

Answer 1

When doing this practice you need to make sure of a two things:

1. Is the new source valid after you decompile and modify it?
2. Does the source rely on any other classes? If so, they must be in the classpath for javac

With some rare exceptions (depending upon what you are trying to hack), this should be enough.

EDIT

It seems the source is not valid. Take your first error message, for example:

C:\Users\Sam\Desktop\DECOMP~1\src\org\bukkit\craftbukkit\CraftServer.java:619: error: not a statement ex; ^ 

There is something that is not a statement in CraftServer.java line 619.

PS, taking a look at bukkit.org, it seems that this software is open source. Do you really need to decompile it?
