Description

For a mojo parameter like

/**
 * @parameter default-value="${project.url}"
 * @required
 */
String url

Maven will not validate whether the default value actually evaluates to a non-null value.

This is a subtle difference from

/**
 * @parameter expression="${project.url}"
 * @required
 */
String url

where the non-null validation will be performed.
