Configuring swagger for multiple API versions

[kriskohlstedt]

Has anyone found a solution for getting grape-swagger to support multiple versions at the same time. For example I have a structure like

/lib/api/root.rb
lib/api/v1/root.rb
lib/api/v2/root.rb
lib/api/v4/root.rb
etc...

If I put the 'add_documentation api_version: "v1"' in any of the root.rb files, swagger does pick up all APIs underneath and mark them as v1 but obviously I'd want those under v2 and v3 to be marked appropriately.

I am able to for example put 'add_documentation api_version: "v2"' in the v2 root.rb but then I only get docs for v2. If I 'add_documentation api_version: '' in all of the root.rb files only 1 gets picked up.

So, is there any way to publish all versions via swagger? Thanks in advance!
