DMG option fails in GitHub Actions CI process

[tofi86]

Hi,

for the following config

{
  "source" : ["target/EPUB-Checker.app"],
  "bundle_id" : "de.paginagmbh.epubchecker",
  "apple_id": {
    "username" : "",
    "password":  "",
    "provider": ""
  },
  "sign" :{
      "application_identity" : ""
  },
  "dmg" :{
    "output_path":  "target/pagina-EPUB-Checker.dmg",
    "volume_name":  "pagina EPUB-Checker"
  }
}

this GitHub Actions Workflow https://github.com/paginagmbh/EPUB-Checker/blob/development/.github/workflows/release.yml fails when gon is trying to create the DMG:

Do you have any idea why this might happen?

Thanks and best regards, Tobias

P.S. locally, the same maven build process including gon works as expected...

Did you ever get this to work? I'm curious if you're running into the problem of accepting prompts as documented in the README https://github.com/mitchellh/gon#prompts or if you found a way around them?

Not sure if this helps.. https://github.com/herrbischoff/awesome-macos-command-line#disk-images

The issue is it works only on a desktop with GUI access.

Did anyone get this working for GitHub Actions/Non-TTY environment?
