Templating project build beyond plugin-versions

[nedtwigg]

Blowdryer 1.7.0 added a plugin-versions feature which has removed a lot of headache from maintaining our fleet of builds.

It would be nice to have similar templating available for e.g GitHub Actions files, maybe .gitattributes, stuff like that. No imminent plans to implement this, but open to PRs.

I lean towards an API along these lines:

// blowdryer-scripts
actions.template <- file whose content is a newline delimited list of paths to copy from scripts into the repository
.github/workflows/gradle-wrapper-validation.yml
.github/workflows/ci.yml

// settings.gradle
blowdryerSetup {
  applyTemplate 'actions.template', {
    omitFile '.github/workflows/ci.yml'
    modifyFile '.github/workflows/gradle-wrapper-validation.yml', {
      replace '8', '11'
    }
  }
}
