Exception Message should be shown rather than "One or more errors occurred."

What You Are Seeing?

Exception messages are not displayed. Instead "One or more errors occurred." is shown as the error message.

What is Expected?

When an exception is thrown with a specific error message, I would expect to see that that text in the console output.

What version of Cake are you using?

Version 0.22.2+Branch.main.Sha.c8630875bc14ce11aa758e0dcd55f691da5f602b

Are you running on a 32 or 64 bit system?

64 bit Windows

What environment are you running on? Windows? Linux? Mac?

64 bit Windows

Are you running on a CI Server? If so, which one?

No. Command line

How Did You Get This To Happen? (Steps to Reproduce)

1. test.cake:

Task("Default")
  .Does(() =>
{
  throw new Exception("Foo");
});

RunTarget("Default");

2. Run cake: Cake test.cake

3. Output:

========================================
Default
========================================
An error occurred when executing task 'Default'.
Error: One or more errors occurred.

I have same problem.
Exception is printed as below when you use netcoreapp1.0 as TargetFrameworks of Cake.exe, but not when net461

.

The phrase One of more errors occured is the message part of an AggregateException, so I suspect this has to do with this change that was introduced recently.

Ah probably I can take a look at sorting that.

I've just been getting this, and wasn't sure what the exception actually was. So I temporarily handled it in a try catch block to dump out the output.

Obviously only a temporary solution until this issue is fixed, but I thought it worth pasting the code here in case anyone else saw this ticket and didn't know what their exception was either ...

try
{
    // Some code
}
catch(AggregateException aex)
{
    aex.Handle(ex => { Console.WriteLine(ex.ToString()); return false; });
}

Hopefully this'll be resolved soon, as that's obviously bloat in my Cake file! :)

@dracan running cake with diagnostic verbosity will give the full stack trace too.

@devlead Ah, cool - I had tried verbose, but not diagnostic.
