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

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]

thanks

[dancrumb]

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

[AaronHarris]

Still broken as of 1/12/2018

[catadincu]

any news on this?

[jayaj1911]

Is this still broken?

[ljnocca]

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]

issue still present

[Ryan-Palmer]

yeah I just hit this :/

[jayaj1911]

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

[Ryan-Palmer]

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 https://github.com/swagger-api/swagger-codegen/issues/9241)

[suhasIVT]

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]

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

[kireyzambon]

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

[RugerSR9]

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]

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

[samheihey]

I had that error too, but then I realize I made 2 mistakes when setting up the controller:
1) Request Method, I changed the method from Get to Post
2) Setting the correct Http Route

After fixing those 2 errors, and the code is generated

[brianpooe]

Any update on this?

[magex9]

Im getting this error on 2.4.13 as well..

Exception in thread "main" java.lang.RuntimeException: missing swagger input or config!
at io.swagger.codegen.DefaultGenerator.generate(DefaultGenerator.java:764)
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]

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
