Null pointer on simple exemple

[rlemaire]

Hi,

I tried to use this plugin and have the following exception.

I'm new to swagger, so maybe I'm missing something.

Here's the routes I add :

GET /resources.json controllers.ApiHelpController.getResources GET /resources.xml controllers.ApiHelpController.getResources

GET /departureTime.json controllers.ApiHelpController.getResource(path = "/admin") GET /departureTime.xml controllers.ApiHelpController.getResource(path = "/admin")

The Controller (I tried removing the @ApiParamsImplicit) : @Api("/admin") public class TestSwaggerController extends Controller {

@Path("/add-employee")
@ApiOperation(value = "Add a new employee", notes = "", responseClass = "string", httpMethod = "POST")
@ApiParamsImplicit({ @ApiParamImplicit(name = "id", value = "id of employee", required = true, dataType = "string", paramType = "query"),
        @ApiParamImplicit(name = "name", value = "Name of employee", required = true, dataType = "string", paramType = "query"),
        @ApiParamImplicit(name = "salary", value = "The salary which the poor soul gets", required = true, dataType = "string", paramType = "query") })
public static Result addEmployee() {
    return ok();
}

}

And the exception.

Hi @rlemaire we've moved the official swagger-play2 module to here:

https://github.com/wordnik/swagger-core/tree/master/modules/swagger-play2

And will have a "release" of it shortly after it reaches feature parity with the JAX-RS version. So can you try that branch, those instructions and post back any issues to there?

Here is a sample project to get you started:

https://github.com/wordnik/swagger-core/tree/master/samples/scala-play2

Hi Ayush,

Thank you very much for your answer.

I already tried this version, but it doesn't compile (at least on my machine), so I though the other version was the right one.

I'm going to follow the project on github to see your releases. We may use it later.

Thats because the latest worknik-oss is not being used. I just replied to that issue here: https://github.com/wordnik/swagger-core/issues/33

@rlemaire the wordnik-oss snapshot is updated in sonatype now, so you should be able to build w/o locally building.
