Code error beyond my repair.

So here's the error I get when I recompile my workspace, a box pops up saying that gradle failed to build the app with a Null Pointer Exception, And when I run the gradle command build I get this popup message:

I looked into the console and there is this:

From this I was able to deduce that the error was with the source file that contained MCreators global variable listing, because I don't have access to this file or even know how to properly fix it, I came here.

I fixed the error, apparently MCreator created the class file and forgot to put the brackets the file looks like this:

public class mcreator_VarList%MINMODNAME%

When it should look like this:

public class mcreator_VarList%MAINMODNAME%
{

}
//Or this
public class mcreator_VarList%MAINMODNAME% { }

Every opening braces { needs one closing braces }. The only purpose of the extra braces is to provide scope-limit . If you put curly braces in the wrong places or omit curly braces where the braces should be, your program probably won't work at all. Moreover, If you don't indent lines of code in an informative manner , your program will still work correctly, but neither you nor any other programmer will be able to figure out what you were thinking when you wrote the code. The error Reached End of File While Parsing is a compiler error and almost always means that your curly parenthesis are not ending completely or maybe there could be extra parenthesis in the end.
