Macro not showed

Hi, I am beginner atlassian developer.
I written first sample helloword, from followed tutorial about create a new macro:

https://developer.atlassian.com/docs/getting-started/set-up-the-atlassian-plugin-sdk-and-build-a-project/create-a-confluence-hello-world-macro

Plugin is showed on add on, but macro helloworld is not showed on macro list view.
I am going crazy. Any idea why ?

thanks

In the tutorial, the number 10 is about logging. Do you see any output there?
Expand the modules in the addons page, are X/X (=all) enabled?
Assuming you kept all same. Edit a page and type “{he” do you see your macro?
