Defining plugin goal at phase - maven

Question

I am trying to define a plugin goal so that it can automatically be executed at a particular phase; say for example the test phase. But I am unable to achieve that. For example I coded the following pom.xml. Notice in my XML <execution> element, I have a <phase> sub-element which is "test". I can execute my goal using the command "mvn antrun:run#ant-echo"; but "mvn test" does not execute that goal. I am using Maven version 3.8.3 and my JDK version is 16.

In order to have your plugin executed during the configured lifecycle phase, you have to specify the plugin goal binding and configuration within the <plugin> section:
