How to check for console errors?

Try and catch.

 

When an exception is thrown, write the stack-trace to the file using a try and catch block.

 

Not sure what you mean,
But here's what @Skionz means

try{
//execute the code
}catch(<exception type>){
//catch an exception and write stack-trace to file.
}

 

Catch the exception and handle it with a catch block.

You may be able to use a PrintStream, calling System.setOut(yourPrintStream) and have it write to the file. I am not completely sure if that would work or if I am making any sense right now.

 

Or...

Code (Text):

try {
// Code
} catch (Exception e) {
this.getConfig().set(String, e.getPrintStackTrace());
// I think.  I'm not using eclipse for this :P
}

 

Syntax error

 

Is getPrintStackTrace even a real method?

 

Yea I know XD

 

I think so.

 

Actually you are making sense @BetaNyan but I don't think it would work.try and cahtch will do the trick.

 

I tried it and it didn't come up I'll look more into it.

 

Luck is very important
