public @interface Parameter

Used to configure your Mojo parameters to be injected by MavenPluginManager.getConfiguredMojo(...).
Beans injected into Mojo parameters are prepared by Sisu JSR330-based container: this annotation is only effective on fields of the Mojo class itself, nested bean injection requires Sisu or JSR330 annotations.

    Specifies that this parameter cannot be configured directly by the user (as in the case of POM-specified configuration). This is useful when you want to force the user to use common POM elements rather than plugin configurations, as in the case where you want to use the artifact's final name as a parameter. In this case, you want the user to modify <build><finalName/></build> rather than specifying a value for finalName directly in the plugin configuration section. It is also useful to ensure that - for example - a List-typed parameter which expects items of type Artifact doesn't get a List full of Strings.
    
    Returns:
    true if the user should not be allowed to configure the parameter directly
    
    Default:
    
    false
