Fix Chocolatey Package

[gep13]

Since we are embedding assemblies into the Chocolatey Package, and the Package Validator rules have been increased, we need to include a verification.txt into the package.

So basically just add a file like below?

VERIFICATION
Verification is intended to assist the Chocolatey moderators and community
in verifying that this package's contents are trustworthy.

This package is published by the Cake Project itself. The binaries are 
identical to other package types published by the project, in particular
the Cake.Portable nuget package.

Yip, that pretty much covers it.

More information here:

https://github.com/chocolatey/package-validator/wiki/VerificationFileMissing

[devlead]

yeah read that, not über clear what the file should contain reading that wiki though :)

[devlead]

See that
Providing checksums in verification is helpful, but OPTIONAL

So above and we should be good to go.

[gep13]

Any suggestions on how the wiki can be improved would be welcome :-)

What does it take to get this approved?
https://chocolatey.org/packages/cake.portable/0.22.2

The problem is the addins - like cake-contrib/Cake.FileHelpers#17 are requiring the 0.22 version.

Chicken and egg!

@waynebrantley the fix is as described above. We need to add the verification.txt file to the package and re-push to chocolatey.org.

In the interim, so can install that version of the chocoatey package by specifying the version number in the command line. Or you can pin to earlier versions of both cake, and cake.filehelpers.
