Command failed java.lang.reflect.UndeclaredThrowableException

[ghost]

SimpleExecutionStrategy throwing UndeclaredThrowableException at ReflectionUtils.invokeMethod.

How do we register (if that is the correct word) our application exceptions that might occur within a command ? I need to capture thrown exceptions correctly.

For example this command makes a remote connection to a service and might fail for a number of reasons.

 @CliCommand(value = "ife scep ca", help = "SCEP get CA certificate")
    public final String ca() throws ClientException, IOException {
        this.cacert = auto.getCaCertificate();
        return "Got CA certificate CN " + this.cacert.getSubjectDN().getName();
    }

I have tried implements ExecutionProcessor also no luck as of yet (exception is null).

Can you clarify exactly what you want to achieve?

If you want to catch exceptions inside the command implementations, then you are certainly allowed to do that (and act on it).
If you simply let exceptions bubble up, then their toString() will be displayed in the shell (in a different color)
Lastly, you may want to have a look at ExecutionProcessor to intercept exceptions globally

Hi Eric, Thank you for getting back to me I have the following test case:

We can clearly see the message from beforeInvocation() (ExecutionProcessor) but it never hits the afterThrowingInvocation().

I had added:

 @Override
    public void afterThrowingInvocation(ParseResult pr, Throwable thrwbl) {
         LOGGER.warn(thrwbl.getLocalizedMessage());
        //
    }   

Am I hitting a bug or doing something wrong ?

May getLocalizedMessage() is blank?
More importantly, what are you trying to achieve in this case? What should happen when an exception happens? Knowing that, maybe I can point you to the best implementation solution.

Thanks, so maybe an example of a command that calls some code that throws an exception like filenotfoundexception and then being able to catch that exception and print it to the shell console.

Any examples?
