[REQ] [Java] [Maven] InputSpec download from url

[Catscratch]

Currently inputSpec must be a file located in the filesystem.

It would be nice to provide an uri like "file:///..." or "http://..." and the maven plugins decides whether it should download the file first or not.

Usually to wanna generate sources for a public service providing a swagger.json file somewhere.

Changes could happen here: https://github.com/OpenAPITools/openapi-generator/blob/master/modules/openapi-generator-maven-plugin/src/main/java/org/openapitools/codegen/plugin/CodeGenMojo.java#L383

I think the input parameter (-i in CLI or inputSpec in plugins) already supports URL. Can you try this one?

@wing328 he is referring to the maven-plugin. I will give it a look.

+1 for https/http supporting

I am using maven plugin for some kind of automatic CI process.

That's a very important feature. APIs are usually published on a web server and you don't want to download it just to generate the code!

There's a work-in-progress PR: https://github.com/OpenAPITools/openapi-generator/pull/2373

Please help test it when you guys have time.

Has this been implemented?

It seems like it has: https://github.com/OpenAPITools/openapi-generator/pull/3826

[Arsennikum]

What about implementation for Gradle plugin?

Looks like it is still not working for redirects: http://petstore.swagger.io/v2/swagger.json

Is it still open? :( It would be so nice feature to use shared api specification between multiple services!

There is an example which works with remote URL: https://github.com/OpenAPITools/openapi-generator/blob/8938f9dea1ef9ba28bf89e0fbb71c33e1c68a665/modules/openapi-generator-maven-plugin/examples/java-client.xml#L51

Maybe you are limited to collapsed ApiSpec.
