How to print all java exceptions on the terminal?

Question

I've noticed that whenever an exception is thrown on the terminal, I often get an abbreviate failure trace such as this:

java.lang.NoClassDefFoundError: javafx/application/Application
at java.lang.ClassLoader.defineClass1(Native Method)
at java.lang.ClassLoader.defineClass(Unknown Source)
at java.security.SecureClassLoader.defineClass(Unknown Source)

... 13 more
Exception in thread "main"

What I want to know is how to print all of the trace, including those ... 13 more.

EDIT: This post has been identified as a possible duplicate of Print full call stack on printStackTrace()? . I did read the latter but didn't find an answer to my question, I only found information on why it happens.

Actually.. it will print entier thing .. what is stopping here is your console... Increase your console's page lines (or make it unlimited), then you will get enterire list — Pavan Kumar K, Jul 24 '15 at 10:08

And how can I implement those changes to my console @PavanKumarK? I'm using win7, by the way, perhaps it's relevant to the question. — Maslor, Jul 24 '15 at 10:10
Why do you want to see 13 more, when they are already present in the printed lines? — Dragan Bozanovic, Jul 24 '15 at 10:28

You can pass the Throwable object (the Exception in your case) to a method like this:

static void printFullTrace(Throwable throwable){
    for(StackTraceElement element: throwable())
        System.out.println(element);
}

The truth is that you are already seeing the whole stack trace in those lines, because a part of it is repeated and so omitted for brevity. You can understand better the mechanism here.

Although this is indeed quite useful information, what I am looking for, if it even exists, is a simple way to make my command line print all the trace, instead of writing "...13 more" @PavanKumarK said in the comments that you could increase your console's page lines but hasn't developed his answer yet... Is it possible? – Maslor Jul 24 '15 at 10:15
@Maslor: I have added it – enrico.bacis Jul 24 '15 at 10:34
Thanks for the clarification! – Maslor Jul 24 '15 at 10:44

StackTraceElement[] stackTraces = Thread.currentThread().getStackTrace();
for (StackTraceElement element : stackTraces) {
    System.out.println(element);
}

I'm looking for an alternative simple method that doesn't require adding code to my application, if it exists. – Maslor Jul 24 '15 at 10:25
http://docs.oracle.com/javase/7/docs/api/java/lang/Thread.html#getStackTrace() is that enough, or I am missing something that you know, but do not want to share ? – Recoba20 Jul 24 '15 at 13:12

You can print the whole stack Traces by below method. Reading the Java Doc for printStackTrace will tell why is this designed this way.

void printAllTraces(Throwable throwable) {
       StackTraceElement[] stackTraces = throwable.getStackTrace();
       for (StackTraceElement stackTrace: stackTraces) {
          System.out.println(stackTrace); 
       }
}

printStackTrace can give only this much and this is designed in order to be concise. So without adding little code I am afraid there is no way you get the full stack trace. – sakthisundar Jul 24 '15 at 10:28

The standard Windows console (cmd) is very short of features, you need to install a console on steroids like ones that are out there, so you'll be able to have a larger scrollback. Take a look into the alternatives listed here.

Personally I use cmder, that is not in the list, but you must test them all and peek which fit you better.
