Files in excludePatterns having a default filtered extension are still included

In the following attached project, we have the following file structure:

archetype.properties
pom.xml
src
└───main
    └───resources
        │   file.txt
        │
        └───.sonar
                file.txt

The use of excludePatterns=**/.sonar/** inside the archetype.properties still results in the creation of the folder src/main/resources/.sonar in the generated archetype.

Running mvn clean archetype:create-from-project -Darchetype.properties=archetype.properties results in the following generated structure inside target\generated-sources\archetype\src\main\resources\archetype-resources:

pom.xml
src
└───main
    └───resources
        │   file.txt
        │
        └───.sonar
                file.txt

The .sonar folder is still present, when it should have been excluded.
