CleanDirectory does not clean readonly files.

What You Are Seeing?

Trying to run CleanDirectory() on a folder that has had some readonly files copied into it using CopyFiles() The issue is that CleanDirectory() fails with access denied on the read only files.

What is Expected?

CleanDirectory() deletes the files even if they are readonly.

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

Add some readonly xsd files to ./Documents/Schemas/ and run the following cake file twice…

Task("Default")
    .Does(() =>
    {
            var schemaFolder = Argument("schemaFolder", "./artifacts/schemas");
            EnsureDirectoryExists(schemaFolder);
            CleanDirectory(schemaFolder);
            var files = GetFiles("./Documents/Schemas/*.xsd");
            CopyFiles(files, schemaFolder);
        });

RunTarget("Default");

+1

I’m trying to make my builds idempotent and when cloning a repo from git, often the .git directory contains read only files which causes DeleteDirectory or CleanDirectory to fail.

What about adding a Force boolean argument (defaulted to false) to Clean/Delete Directory? I’d be happy to contribute.

Related to #1564

Now that #1574 is merged, IFile will support changing file attributes in v0.22. This means we could have a overload which has a force option (just like we did with DeleteDirectory in #1574)
