Please provide more information about what exactly you're trying to do, such as the exact command you're running.

dariota · 2017-09-18T20:44:31Z

Sorry, that yaml's a bit broken. Could you send it again in code formatting?

dariota · 2017-09-23T16:21:11Z

I've tracked the issue to this line in swagger-parser. Correcting this to openapi let the generator complete successfully with the provided example yaml, so if you want a quick fix you could try that.

The feature/3.0.0-rc2 branch there has thoroughly changed the structure of that directory, so I suspect there are changes made/being made which the 3.0.0 swagger-codegen branch isn't yet synchronised with.

chaoshen1024 · 2017-09-26T13:17:38Z

thanks

dancrumb · 2017-10-21T16:28:02Z

Is there any update on when this fix will be available in a snapshot?

AaronHarris · 2018-01-12T20:21:17Z

Still broken as of 1/12/2018

catadincu · 2018-02-28T18:57:46Z

any news on this?

jayaj1911 · 2019-01-28T12:22:00Z

Is this still broken?

ljnocca · 2019-02-15T15:50:34Z

I'm getting this same error when trying to use Open Api spec 3. However, it works fine with spec 2. Anyone have this issue as well?

riteshkapse · 2019-03-01T11:26:09Z

issue still present

Ryan-Palmer · 2019-03-07T14:24:14Z

yeah I just hit this :/

jayaj1911 · 2019-03-08T05:54:07Z

Try using this experimental openapi codegen instead. It is v light and works for me: https://github.com/Mermade/openapi-codegen

Ryan-Palmer · 2019-03-08T09:15:18Z

I tried downloading Swagger codegen 3.0.5 and that 'worked' with OpenApi 3 pretty much, although for some reason it misses out the names of properties in the model constructors and messes up the path to the projects from my sln file although I think these are probably all c# specific. (mentioned here #9241)

suhasIVT · 2019-03-22T13:27:16Z

Has this worked for anyone ? OpenApi Spec 3 does not work with io.swagger swagger-codegen-maven-plugin 2.3.1. - I'm getting this error when trying to use Open Api spec 3. However, it works fine with spec 2.
Error - (**java.lang.RuntimeException: missing swagger input or config!)

riteshkapse · 2019-03-22T13:36:26Z

Download source and generate swagger-codegen-cli.jar jar locally. This worked for me.

kireyzambon · 2019-04-08T12:09:29Z

hello, i have the same error with https://developer.atlassian.com/cloud/jira/platform/swagger-v3.v3.json

RugerSR9 · 2019-06-12T20:32:33Z

Download source and generate swagger-codegen-cli.jar jar locally. This worked for me.

Tried that and still get the same error:

Exception in thread "main" java.lang.RuntimeException: missing swagger input or config! at io.swagger.codegen.DefaultGenerator.generate(DefaultGenerator.java:747) at io.swagger.codegen.cmd.Generate.run(Generate.java:285) at io.swagger.codegen.SwaggerCodegen.main(SwaggerCodegen.java:35)

Edit: I ended up using @openapitools/openapi-generator-cli and it worked flawlessly.

daniilmatafonov · 2019-08-16T09:49:31Z

I also gettting this error while using swagger-codegen-maven-plugin 2.4.7. Could you please fix this?

samheihey · 2019-08-29T08:58:59Z

I had that error too, but then I realize I made 2 mistakes when setting up the controller:

Request Method, I changed the method from Get to Post
Setting the correct Http Route

After fixing those 2 errors, and the code is generated

brianpooe · 2020-03-10T09:47:47Z

Any update on this?

magex9 · 2020-03-31T10:59:28Z

Im getting this error on 2.4.13 as well..

at io.swagger.codegen.cmd.Generate.run(Generate.java:299)
at io.swagger.codegen.SwaggerCodegen.main(SwaggerCodegen.java:35)

Im using openapi 3.0.0 yaml, but converted it to json, neither work.

beRoberto · 2020-04-15T19:10:06Z

By default the master branch supports 2.0. The 3.0 support is on the 3.0.0 branch, you have to change to this branch and build again to get it working.

git clone https://github.com/swagger-api/swagger-codegen.git
cd swagger-codegen
git checkout 3.0.0
# after this build as you please
mvn clean package

salvatorevitale-github · 2021-01-29T00:19:04Z

Check using single space and not tab!

Kolyunya · 2023-01-01T22:53:25Z

I believe the issue here is that we are using a very old codegen version.

It turns out the latest published docker image is 2.4.29 which doesn't support OpenAPI v3.

Would the Swagger team be so kind to publish a fresh docker image for us, please? It would be really nice if we could use a dockerized version of the codegen.

Thank you!

DanTurco · 2023-10-26T14:02:31Z

Download source and generate swagger-codegen-cli.jar jar locally. This worked for me.

Tried that and still get the same error:

Exception in thread "main" java.lang.RuntimeException: missing swagger input or config! at io.swagger.codegen.DefaultGenerator.generate(DefaultGenerator.java:747) at io.swagger.codegen.cmd.Generate.run(Generate.java:285) at io.swagger.codegen.SwaggerCodegen.main(SwaggerCodegen.java:35)

Edit: I ended up using @openapitools/openapi-generator-cli and it worked flawlessly.

openapi-generator-cli has issues too

docker run --rm -v C:\dev\client\projects:/local openapitools/openapi-generator-cli generate -i \ /local/temp/swagger.json\ -l typescript-angular -o /local/api-swagger-client/src

DanTurco · 2023-10-26T14:04:10Z
