We've added a new generator to OpenAPI Generator (https://github.com/OpenAPITools/openapi-generator) to generate Scala (sttp - https://github.com/softwaremill/sttp) API clients. To generate the client given an [OpenAPI/Swagger specification file](https://github.com/OAI/OpenAPI-Specification), please follow 3 simple steps below:<p>1. Download the Java JAR: https://oss.sonatype.org/content/repositories/snapshots/org/openapitools/openapi-generator-cli/4.3.0-SNAPSHOT/openapi-generator-cli-4.3.0-20200304.092413-177.jar<p>2. Rename the JAR as "openapi-generator-cli.jar"<p>3. Run the following command to generate a Scala (sttp) API client for the Petstore API: https://raw.githubusercontent.com/OpenAPITools/openapi-generator/master/modules/openapi-generator/src/test/resources/2_0/petstore.yaml<p>Mac/Linux:<p>$ java -jar openapi-generator-cli.jar generate -g scala-sttp -i https://raw.githubusercontent.com/OpenAPITools/openapi-generator/master/modules/openapi-generator/src/test/resources/2_0/petstore.yaml -o /var/tmp/scala-sttp/<p>Windows:<p>$ java -jar openapi-generator-cli.jar generate -g scala-sttp -i https://raw.githubusercontent.com/OpenAPITools/openapi-generator/master/modules/openapi-generator/src/test/resources/2_0/petstore.yaml -o C:\tmp\scala-sttp<p>If you've any feedback or question, please let us know via https://github.com/OpenAPITools/openapi-generator/issues/new.<p>The new generator will be included in the upcoming v4.3.0 stable release.<p>Thanks for the new generator by Aleksandr Nekrasov (https://github.com/chameleon82)<p>Ref: https://github.com/OpenAPITools/openapi-generator/pull/5429
