The following example will call JetBrains dupFinder and output the number of warnings.

To call JetBrains dupFinder from a Cake script you need to add the JetBrains.ReSharper.CommandLineTools:

#tool "nuget:?package=JetBrains.ReSharper.CommandLineTools"

To read issues from dupFinder log files you need to import the core addin and the dupFinder support:

#addin "Cake.Issues"
#addin "Cake.Issues.DupFinder"

Please note that you always should pin addins and tools to a specific version to make sure your builds are deterministic and won't break due to updates to one of the packages.

See pinning addin versions for details.

We need some global variables:

var logPath = @"c:\build\dupfinder.xml";
var repoRootPath = @"c:\repo";

The following task will run JetBrains dupFinder and write a log file:

Task("Analyze-Project").Does(() =>
    // Run DupFinder.
    var settings = new DupFinderSettings() {
        OutputFile = logPath

    DupFinder(repoRootPath.CombineWithFilePath("MySolution.sln"), settings);

Finally you can define a task where you call the core addin with the desired issue provider.

    .Does(() =>
        // Read Issues.
        var issues =

        Information("{0} issues are found.", issues.Count());
