runTarget missing or invalid - on GWT Maven project

Question

When trying to run our GWT app from maven command line, I get the following error:

The parameters 'runTarget' for goal org.codehaus.mojo:gwt-maven-plugin:2.4.0:run are missing or invalid.

However, this is with the following in the pom.xml:

<plugin>
            <groupId>org.codehaus.mojo</groupId>
            <artifactId>gwt-maven-plugin</artifactId>
            <!-- <version>2.5.0</version> 2.1.0-1 -->
            <version>${gwt.version}</version>
            <configuration>
                <configuration>
                    <runTarget>com.magick.webtrader/Webtrader.html</runTarget>
                    <buildOutputDirectory>${project.build.outputDirectory}</buildOutputDirectory>
                    <generateDirectory>${project.build.directory}/generated-sources/gwt</generateDirectory>
                    <hostedWebapp>${webappDirectory}</hostedWebapp>
                    <copyWebApp>true</copyWebApp>
                    <draftCompile>true</draftCompile>
                    <webXml>${basedir}/war/WEB-INF/web.xml</webXml>
                </configuration>

            </configuration>

            <executions>
                <execution>
                    <goals>
                        <goal>compile</goal>
                        <goal>test</goal>
                        <goal>generateAsync</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>

What is it I'm doing wrong?

Thanks

I don't think you need to nest those <Configuration> elements i.e. <Configuration> inside another <Configuration>. Try fixing this and see if it works. On a side note, you shouldn't need to specify parameters like <buildOutputDirectory> explicitly if you're anyway using the default values.
