guardrailTasks in Compile := List(

)Alternatively use the guardrailDiscoveredOpenApiFiles setting to automatically discover OpenAPI spec files under src/main/openapi or src/test/openapi (see the test for full example):
Compile / guardrailTasks := (Compile / guardrailDiscoveredOpenApiFiles).value.flatMap { openApiFile =>
List(
ScalaClient(openApiFile.file, pkg = openApiFile.pkg, framework = "http4s"),
ScalaServer(openApiFile.file, pkg = openApiFile.pkg, framework = "http4s")
)
}
