Way to create swagger.json automatically

[akkihan]

Hello,
I am interested in a way to create a swagger.json automatically during the application start or build phase.
Currently, I manually do a call to GET /swagger.json endpoint which returns the generated JSON file.
Is there any way I can automate this procedure?

Thanks

How is this project even working for you? Arent you on play 2.7 or newer? Thanks

[akkihan]

Yes, I am on play 2.7. Every time to create swagger documentation I call the endpoint. What I would like to achieve it to be created automatically, e.g. when I build or run the app.
Thanks

I'm one step behind you, when I do as it says and add this:

libraryDependencies ++= Seq(
  "io.swagger" %% "swagger-play2" % "2.0.1-SNAPSHOT"
)

it looks for a jar on mavencentral that isn't here:

https://mvnrepository.com/artifact/io.swagger/swagger-play2 - 2.0.1-SNAPSHOT ain't there
How did you solve this?

[akkihan]

This is the one for me:
"io.swagger" %% "swagger-play2" % "1.6.1"
try this one

[robertofabrizi]

That is labeled to support up to scala 2.12, but I'm on 2.13...

[akkihan]

I think I had that issue as well when I tried to switch the scala version to 2.13. Eventually I used scala 2.12.19 and following swagger dependency:
"io.swagger" %% "swagger-play2" % "1.7.1",

[robertofabrizi]

Ah ok you downgraded the scala version. I'm a bit scared to do that just for this module to be honest.

I want to do it at build time, I believe this would have to be some kind of SBT or Maven plugin.

If you want to do it at startup, without calling the endpoint swagger.json, you could call directly the underlying Swagger controller ApiHelpController, there are several methods that could use depending on your need.

I published a plugin for this: https://github.com/dwickern/sbt-swagger-play
