build.gradle.kts build openAPI classes from different interfaces

I use build.gradle.kts build file to create the client stub from an openApi description yaml file.

This work well for only one interface (interface1.yaml)

To create the stub I use :
gradlew openApiGenerate

Snippend form my build.gradle.kts file :

<!-- begin snippet: js hide: false console: true babel: false -->

<!-- language: lang-java -->

openApiGenerate {
    generatorName.set("kotlin")
 
    inputSpec.set("$rootDir/sharedSDK/openApi/interface1.yaml")
 
    outputDir.set("$rootDir/sharedSDK/")
    configOptions.set(mapOf( "dateLibrary" to "java8" ))

    modelPackage.set("package.inteface1.model")
  
    library.set("multiplatform") 
    
    generateModelTests.set(false)
    generateApiTests.set(false)
    generateModelDocumentation.set(false)
    generateApiDocumentation.set(false)
    modelNamePrefix.set("V2")  

    globalProperties.set(
        mapOf(
            //"apis" to "false",
            //"models" to "true"
            "models" to "" // generate only model stuff
        ))
}

<!-- end snippet -->

Now I need to generate the sub classes for a second interface form a different yaml description (interface2.yaml)

How to do this ?

2 openApiGenerate { ... } task in one file didn't work

Is there a way to pass my openApiGenerate { ... } definition to an customer task

Thanks

Define your tasks by type

Gradle allows you to define multiple tasks of the same type. For kotlin, you can do this as follow:

tasks.register<GenerateTask>("GenerateInterface1"){
    generatorName.set("kotlin")
 
    inputSpec.set("$rootDir/sharedSDK/openApi/interface1.yaml")
 
    outputDir.set("$rootDir/sharedSDK/")
    configOptions.set(mapOf( "dateLibrary" to "java8" ))

    modelPackage.set("package.inteface1.model")
  
    library.set("multiplatform") 
    
    generateModelTests.set(false)
    generateApiTests.set(false)
    generateModelDocumentation.set(false)
    generateApiDocumentation.set(false)
    modelNamePrefix.set("V2")  

    globalProperties.set(
        mapOf(
            //"apis" to "false",
            //"models" to "true"
            "models" to "" // generate only model stuff
        ))
}

Shared Config

If you are using a lot of the same config options, you can move them to their own file. This has the added benefit of making your tasks much more concise, but you will still need to define a few properties specific to each task.

tasks.register<GenerateTask>("GenerateInterface1"){
    generatorName.set("kotlin")
    inputSpec.set("$rootDir/sharedSDK/openApi/interface1.yaml")
    outputDir.set("$rootDir/sharedSDK/")
    configFile.set("$rootDir/sharedSDK/generatorConfig.yml")
    modelPackage.set("package.interface1.model")
}

tasks.register<GenerateTask>("GenerateInterface2"){
    generatorName.set("kotlin")
    inputSpec.set("$rootDir/sharedSDK/openApi/interface2.yaml")
    outputDir.set("$rootDir/sharedSDK/")
    configFile.set("$rootDir/sharedSDK/generatorConfig.yml")
    modelPackage.set("package.interface2.model")
}

Now you can move all your configuration settings to your yaml file to be shared by both generators.
