Hi @heliang666s ,
Thanks for the helpful explanation that really clears things up!
I now understand that service registration with Nacos only occurs when the application is actually running, not during the build process with mvn clean install. I’ll go ahead and run the application after packaging it and check the Nacos console for any registered services.
Also, could you please let me know which module in the project I should start to test the Nacos service registration?
I’ll be sure to share any errors or configurations if I encounter issues during runtime. Appreciate your support!
Best regards,
Ankit

Hi @ankitshokeen, thanks for the report and your willingness to contribute!
Just a quick clarification: running `mvn clean install` will not trigger service registration to Nacos, because Dubbo only registers services at runtime, when the application is actually started (e.g., via `java -jar`,` main()` method in IDE, or `Spring Boot startup`).
The `mvn clean install` command is purely for building the project — compiling, running tests, packaging, and installing artifacts into the local Maven repository. It does not run your service or trigger any registry behavior.
If you’re expecting the service to register itself to Nacos, please try running the application (after mvn clean package) and then check the Nacos console to verify the service is properly registered.
Let me know if you're still seeing errors during build or at runtime — feel free to share stack traces or configs, and I’d be happy to take a deeper look!
Thanks again!
