  <description>
    Test to check that the custom settings.xml is automatically excluded from the project scanner. This is a convenience
    feature to support the following common directory layout
      src/it/
        project1/
        project2/
        settings.xml
    in combination with the POM include pattern "*" required to select POM-less directories. Without excluding settings.xml,
    it would be considered a POM and cause a build failure.
