swagger ui is not available for api-gateway

api-gateway has controller that server index.html of swagger-ui:

eventuate-tram-sagas-examples-customers-and-orders/api-gateway-service/src/main/java/io/eventuate/examples/tram/sagas/ordersandcustomers/apigateway/common/SwaggerController.java

Lines 8 to 14 in afe7b6a

    
           @RestController 
        
           public class SwaggerController { 
        
             @GetMapping("/swagger-ui.html") 
        
             public Resource getFile() { 
        
               return new ClassPathResource("META-INF/swagger-ui/index.html"); 
        
             } 
        
           }

But there is no such file "META-INF/swagger-ui/index.html"

Problem is that META-INF of eventuate-util-swagger-ui is not unpacked in api-gateway jar

Solution is define task to unpack:

bootJar {
    requiresUnpack '**/eventuate-util-swagger-ui-*.jar'
}

	@RestController
	public class SwaggerController {
	@GetMapping("/swagger-ui.html")
	public Resource getFile() {
	return new ClassPathResource("META-INF/swagger-ui/index.html");
	}
	}
