Confluence Macro Not displayed in Macro list

Following the Hello world Macro from here

I followed the steps and created and packaged the project with atlas-mvn package, with no errors. The Hello world macro is not displayed in Macro Dialog in confluence.

Any other steps to be followed…

Did the terminal where you executed atlas-run produce any output after running atlas-mvn package?
Did you check that your plugin was indeed installed after running atlas-mvn package?

No error in terminal the script executed succesfully. Yes the plugin was installed, I could see the response in terminal as specified in the documentation.
