I'm trying a project setup with vertx-codegen for @DataObject, vertx-service-proxy for @ProxyGen and vertx-web-api-service for @WebApiServiceGen and during compiling I get the following error:

Could not generate element for io.slinkydeveloper.debtsmanager.models.AuthCredentials: Attempt to recreate a file for type io.slinkydeveloper.debtsmanager.models.AuthCredentialsConverter

I import all three deps as processor

Tested with openjdk 8/9/11

After some investigation I found that during compilation code generation maven executes both CodegenProcessor and WebApiServiceGenProcessor (the class that extends CodegenProcessor). Both generate code and when WebApiServiceGenProcessor tries to write the code the code generation step fails

Ok so after more investigation I have a clear view on it. When you load two or three annotation processors, the jvm compare processors each other. WebApiServiceGenProcessor overrides Set<String> getSupportedAnnotationTypes() and jvm triggers code generation in both classes.

I think that was resolved with the usage of a single generator
