Unable to locate logback.xml from scalatest

[maxMidius]

I am using scalatest-maven-plugin with a config which looks like this

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-surefire-plugin</artifactId>
            <version>2.7</version>
            <configuration>
                <skipTests>true</skipTests>
            </configuration>
        </plugin>
        <!-- enable scalatest -->
        <plugin>
            <groupId>org.scalatest</groupId>
            <artifactId>scalatest-maven-plugin</artifactId>
            <version>1.0</version>
            <configuration>
                <reportsDirectory>${project.build.directory}/surefire-reports</reportsDirectory>
                <junitxml>.</junitxml>
                <filereports>MyProj_TestSuite.txt</filereports>
                <forkMode>never</forkMode>
            </configuration>
            <executions>
                <execution>
                    <id>test</id>
                    <goals>
                        <goal>test</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>

I have a logback.xml in my src/test/resources which gets copied over to target/classes
Have spent a whole day to figure out why this is not being picked up -- using the following

<runpath> ${project.basedir}/target/classes </runpath>

If I run it like this

mvn test -Dlogback.configurationFile=./src/test/resources/logback.xml - it works

So I am wondering if you can please help me understand how to do this from inside the pom.xml

Thank you
