There's no reason for a main
method to throw
anything. After all, what's going to catch it?
Instead, the method should itself gracefully handle any exceptions that may bubble up to it, attach as much contextual information as possible, and
perform whatever logging or user communication is necessary, and exit
with a non-zero (i.e. non-success) exit code if necessary.
public static void main(String args[]) throws Exception { // Noncompliant doSomething(); }
public static void main(String args[]) { try { doSomething(); } catch (Throwable t) { log.error(t); System.exit(1); // Default exit code, 0, indicates success. Non-zero value means failure. } }
