Template for try/catch block [message #758521]

I've seen that when I'm not handling an exception in Java, Eclipse provides me with a "surround with try/catch block" quick fix.

That fix seems to make use of a template, but I can't find it.

I'd like to configure that template so that the catch block prints on System.err some info:
- name of the exception
- name of the method that invoked it
- name of the class
- name of the thread (eventually)

Is this possible to do this automatically?

- Open 'Templates' view.
- Look for a template named 'try'

Thank you.

Do I have to use reflection to know the name of the kind of exception that's prompted, or is there some {} parameter I can refer to?

For example
System.err.println("Exception" + {exception_type} + "in method" + {method} + "of class" + {class});

Don't think it is possible to get the exact exception type thrown from
selected code via a template.

The complete list of template variables is here -

Try:

System.out.println(${exception_var}.getClass().getName());
System.out.println(${exception_var}.getStackTrace()[0].getMethodName());
System.out.println("${enclosing_type}");
System.out.println(Thread.currentThread().getName());
