XSD Not Picked Up by XMLBeans Maven Plugin

I am trying to generate XMLBeans classes using maven plugin. I have configured this in my POM file, but every time I do a clean install, I see this in the debug logs:

[DEBUG] Number of XSD Files: 0

[DEBUG] Number of WSDL Files: 0

[INFO] Nothing to generate.

My plugin is defined as:

        <plugin>
            <groupId>org.codehaus.mojo</groupId>
            <artifactId>xmlbeans-maven-plugin</artifactId>

            <executions>

                    <goals>

                        <schemaDirectory>${project.basedir}\src\main\resources\XSDFiles\</schemaDirectory>
                        <generatedSchemaDirectory>${project.basedir}\src\main\resources\XSDFiles\</generatedSchemaDirectory>
                        <sourceGenerationDirectory>${basedir}\src\main\java\</sourceGenerationDirectory>                            
                        <verbose>true</verbose>
                    </configuration>
                </execution>
            </executions>
        </plugin>

This was a buggy plugin. Switching to an older version helped.
