msbuild: Anyway to show summary and use verbosity=minimal

Question

I have a batch file for building .net solutions and am trying to get the verbosity level to be minimal which only shows which project is building and any warnings and/or errors but would also like to see the summary at the end with number of warnings and errors plus the build time.

I have tried multiple combinations of verbosity and /v and /cpl but it seems you can only get too much output + summary or right minimal output and no summary

Any ideas?

Thanks in advance

You can write a custom logger as explained here: http://msdn.microsoft.com/en-us/library/ms171471.aspx

Here's a bit of code to get you started:

public class SummaryLogger : Logger
{
    int warningCount = 0;
    int errorCount = 0;

    public override void Initialize(IEventSource eventSource)
    {
        eventSource.WarningRaised += eventSource_WarningRaised;
        eventSource.ErrorRaised += eventSource_ErrorRaised;
        eventSource.BuildFinished += eventSource_BuildFinished;
    }

    void eventSource_WarningRaised(object sender, BuildWarningEventArgs e)
    {
        warningCount++;
        Console.WriteLine("Warning: " + e.Message);
    }

    void eventSource_ErrorRaised(object sender, BuildErrorEventArgs e)
    {
        errorCount++;
        Console.WriteLine("Error: " + e.Message);
    }

    void eventSource_BuildFinished(object sender, BuildFinishedEventArgs e)
    {
        Console.WriteLine("MSBuild Finished: " + errorCount + " errors | " + warningCount + " warnings.");
    }
}

This logger logs Warnings, Errors and Summarises the amount of errors and warnings. You'll need to add a little bit of code for time and projects, so that it is exactly what you want.

To use it, you call MSBuild with the following params added to it:

/nologo /noconsolelogger /logger:pathTo/SummaryLogger.dll
