Empty folders are not included in a ZIP archive

See original GitHub issue

What You Are Seeing?

I’m trying to create a ZIP archive with pre-defined folder structure. Some folders are empty. After using Zip("./Package", "Package.zip");, I see that Package.zip is created, but when I look inside it, there are no empty folders. Only folders with files are included.

What is Expected?

I expect empty folders to be present in the ZIP archive.

What version of Cake are you using?

0.16.2.

Are you running on a 32 or 64 bit system?

64-bit.

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

  • Windows 10 (1511).
  • Ubuntu 16.04.1.

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

No.

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

Create the following folder structure:

+ Package
|  + Empty
|  + NotEmpty
|  |  - File.txt

In the build.cake perform Zip("./Package", "Package.zip");.

We just call out to the 7zip binary to compress as all the other options aren’t very good. You’d need to extend this to be cross-platform, but for Windows something like this should work:

<?xml version="1.0" encoding="utf-8"?>
<packages>
    <package id="Cake" version="0.16.2" />
    <package id="7-Zip.CommandLine" version="9.20.0" />
</packages>

Task("Zip-Files")
    .IsDependentOn("Build-Environment-Files")
    .Does(() =>
{
    var packageFile = File("project-v" + parameters.Version.SemVersion + ".7z");
    var packagePath = "../" + packageFile;

    var exitCodeWithArgument = StartProcess("tools/7-Zip.CommandLine/tools/7za", new ProcessSettings { 
        Arguments = "a " + packagePath + " " + "./* -mx=5",
        WorkingDirectory = parameters.Paths.Directories.Package
    });
});

As the issue is in the .NET framework I’m going to go ahead and close this issue. Big thanks for your input and research on the issue.
