**NOTE** Convention is to use kebab casing for names passed to `-n`. Example, `scala-finatra` would become `ScalaFinatraGenerator`.

To compile your library, enter the `out/generators/my-codegen` directory, run `mvn package` and execute the generator:

java -cp out/codegens/customCodegen/target/my-codegen-openapi-generator-1.0.0.jar:modules/openapi-generator-cli/target/openapi-generator-cli.jar \

org.openapitools.codegen.OpenAPIGenerator generate -g my-codegen \

-i https://raw.githubusercontent.com/openapitools/openapi-generator/master/modules/openapi-generator/src/test/resources/2_0/petstore.yaml \

-o ./out/myClient

For Windows users:

Install your library to your local maven repository by running:

This will install `org.openapitools:my-codegen-openapi-generator:1.0.0` to your local maven repository.

You can use this as additional dependency of the `openapi-generator-maven-plugin` plugin and use `my-codegen` as `generatorName` value:

<plugin>

<groupId>org.openapitools</groupId>

<artifactId>openapi-generator-maven-plugin</artifactId>

<version>${openapi-generator-version}</version>

<executions>

<execution>

<id>generate-client-code</id>

<goals>

<goal>generate</goal>

</goals>

<configuration>

<generatorName>my-codegen</generatorName>

<!-- other configuration ... -->

</configuration>

</execution>

</executions>

<dependencies>

<dependency>

<groupId>org.openapitools</groupId>

<artifactId>my-codegen-openapi-generator</artifactId>

<version>1.0.0</version>

</dependency>

</dependencies>

</plugin>

If you publish your artifact to a distant maven repository, do not forget to add this repository as `pluginRepository` for your project.

You may not want to generate *all* models in your project. Likewise you may want just one or two apis to be written. If that's the case, you can use system properties to control the output:
