Which of the following is a valid example of how nonFilteredFileExtensions are declared in the Maven plugin configuration?

• A. nonFilteredFileExtensions with multiple nonFilteredFileExtension child elements
• B. nonFilteredExtensions with single nonFilteredFileExtension
• C. filterNonFilteredFileExtensions
• D. nonFilteredFileExtension tag inside a different plugin

Answer: (A)

NonFilteredFileExtensions is represented as a collection in the plugin configuration. In a Maven POM, a list is expressed by a parent element named nonFilteredFileExtensions that contains one or more nonFilteredFileExtension elements, each providing a value. This pattern is exactly how Maven maps a list parameter for a plugin. For example, you would declare multiple nonFilteredFileExtension entries inside the nonFilteredFileExtensions parent. This makes the configuration valid because it matches the expected structure: a list container with repeated item elements. The other formats either change the element name, place the setting in the wrong plugin, or don’t use the list structure the plugin expects, so they don’t align with how nonFilteredFileExtensions is defined.
