checksum Post-Processing not running

[Stuart Luscombe]

For some reason I cannot get the checksum Post-Processing to run correctly.

The error I'm getting is:

* Post-processor failed: unable to create file packer-centos73/<no value>_<no value>.checksum: open packer-centos73/<no value>_<no value>.checksum: The filename, directory name, or volume label syntax is incorrect.

==> Some builds didn't complete successfully and had errors:

--> hyperv-iso: 1 error(s) occurred:

* Post-processor failed: unable to create file packer-centos73/<no value>_<no value>.checksum: open packer-centos73/<no value>_<no value>.checksum: The filename, directory name, or volume label syntax is incorrect.

Below is the post-processors part of my packer json.

  "post-processors":[

   {

     "type": "checksum",

     "checksum_types": ["sha1"],

     "output": "{{user `output_directory`}}/{{.BuildName}}_{{.ChecksumType}}.checksum"

   },

   {

     "type": "manifest",

     "output": "{{user `output_directory`}}/manifest.json",

     "strip_path": true

   }

 ]

The manifest part is running OK and is creating the file, so I don't understand why the checksum is not working.

Platform I'm building on is Windows 10 1703 and builder type is hyperv-iso.

Any ideas?

Hurrah, I've never found a bug before! :-)

Thanks for the quick PR. Does this get incorporated straight into a downloadable build from packer.io, or should I just clone/build from the repo?

[Rickard von Essen]

It has been merged to master and will be in the next release (1.0.3).
But it's quite simple to build from source, see
https://github.com/hashicorp/packer/blob/master/CONTRIBUTING.md#setting-up-go-to-work-on-packer
(at least if your not on Windows).

I am running Windows, but I like a challenge, so I'll give it a go! :-)

[Rickard von Essen]

shouldn't be too hard. Just some more steps and things to install
(git, make, and go )
