Compiler exceptions should be visible at default verbosity in dotnet build #21814

svick · 2017-08-30T16:24:36Z

Version Used: .Net Core 2.0

Steps to Reproduce:

Create a .Net Core project that causes the C# compiler to throw an exception and run dotnet build. For example, in .Net Core 2.0 that can be code that triggers #21645:

public class Class1
{
    static void Test()
    {
        bool outside = true;

        void Inner()
        {
            void Bar()
            {
            }

            void Foo()
            {
                Bar();

                bool captured = outside;
            }
        }
    }
}

Expected Behavior:

dotnet build shows the exception.

Actual Behavior:

The output of dotnet build is not very useful in diagnosing the issue:

To see the exception, you have to use dotnet build /v:n, which also includes lots of irrelevant information:

@jaredpar Do you think it is reasonable to aim to do this (have the compiler build task print detailed exception info when the compiler crashes) in the 15.5 timeframe?

jaredpar · 2017-09-15T21:09:45Z

yes definitely.

nguerrera · 2017-09-18T19:56:26Z

@jaredpar Is there something that can be set in msbuild to bump the csc.exe verbosity without bumping the entire build to /v:diag, which spews a ton of other stuff to the console?

jaredpar · 2017-09-18T20:21:31Z

i was imagining no msbuild work here. Rather we just wrap our main method with try catch and print from there.

nguerrera · 2017-09-19T19:11:11Z

@jaredpar I was asking something different: Is there a workaround with currently shipped bits other other than msbuild /v:normal or /v:diag? One which causes the stack trace to be dumped on compiler crash without otherwise making the entire build more verbose?

jcouv · 2017-10-06T23:02:27Z

Relates to #22332

When Roslyn fails it should format callstacks to enter the build's error log #23743
