logback.xml not excluded in final jar artifact

Hello,

is there a particular reason to not exclude logback.xml from final jar artifact like it is done with swagger-codegen for instance

https://github.com/swagger-api/swagger-codegen/blob/3.0.0/modules/swagger-codegen/pom.xml

        <resources>
            <resource>
                <directory>src/main/resources</directory>
                <excludes>
                    <exclude>logback.xml</exclude>
                </excludes>
            </resource>
        </resources>

I use it as a dependency ( maybe I am wrong ) and I suspect it changed our default logging configuration

https://github.com/swagger-api/swagger-codegen-generators/blob/master/src/main/resources/logback.xml

    <root level="error">
        <appender-ref ref="STDOUT"/>
    </root>

Start by inspecting the Maven resource configuration that builds the final JAR and compare it with the referenced swagger-codegen pom.xml. Check whether logback.xml is included in the artifact and whether it changes dependency logging. Done means the resource is excluded from the final JAR without breaking the build.
