Specify branch, tag, or revision for git clone

[daharon]

I want to use the application resource in such a way that I can specify the tag to clone using Git. Like so:

application '/srv/my-app' do
  git 'https://github.com/daharon/my-app.git' do
    revision 'v1.0.0'  # A git tag.
  end

  bundle_install
  rails
  unicorn
end

The above fails, though.

How can I specify the tag or commit hash of the Git repository that I wish to clone?

That should work fine.

This is the specific error I'm seeing:

I realized what the error was, though.

The following code works:

application '/srv/my-app' do
  git do
    repository 'https://github.com/daharon/my-app.git' 
    revision 'v1.0.0'  # A git tag.
  end

  bundle_install
  rails
  unicorn
end

You need to depend on application_git too if you want to use the shorter syntax.
