Maven - add source dependency; but no java source files available in eclipse for GWT compile

Usually the below pom config works for me. I've been successful in the past at adding my jar file's source to my projects as a dependency?

I have two jar files defined like so:

<dependencies>  
  <dependency>  
    <groupId>myGroup</groupId>  
    <artifactId>myJar</artifactId>  
    <version>4.0</version>   
    <type>jar</type>  
    </dependency>    
  <dependency>  
    <groupId>myGroup</groupId>  
    <artifactId>myJar</artifactId>  
    <version>4.0</version>  
    <type>jar</type>  
    <classifier>sources</classifier>  
  </dependency>  
</dependencies>

When I open up the myJar-4.0-sources.jar file from windows explorer view, I see all the java source files in it associated packages. But when I look in my eclipse project in my maven dependencies I only see xml files and no java files for myJar-4.0-sources.jar

BTW, regardless if I run the maven build inside eclipse or outside, it complains that there is no source code for classes that should be found in myJar-4.0-sources.jar.

BTW, this is a GWT compile.

Here is the actual error message:

Does anybody have any idea why this is the case?

GWT looks for dependency sources in the same JAR as the compiled class files. Since the library is under your control your best course is to include the class files and the source files in the same JAR. To do so add a <resource> to the <build> section of the POM (assuming standard Maven source layout):

<project>
  <build>
    <resources>
      <resource>
        <directory>src/main/java</directory>
      </resource>
    </resources>
  </build>
</project>

<project>
  <build>
    <resources>
      <!-- include the source files in our main jar for use by GWT -->
      <resource>
        <directory>${project.build.sourceDirectory}</directory>
      </resource>
      <!-- and continue to include our standard resources -->
      <resource>
        <directory>${basedir}/src/main/resources</directory>
      </resource>
    </resources>
  </build>
</project>

I finally figured out my problem was. It was my .gwt.xml file. It was not referencing the GWT classes correctly. Not that I solved this, I believe the original way I wanted to reference my source library via the source jar file will work. Thanks.
