Use maven-antrun-plugin like this will do the necessary job to solve this issue 
:

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-antrun-plugin</artifactId>
  <version>1.7</version>
  <executions>
    <execution>
      <!-- Use 'package' instead of 'install' if you want the Driver to be available for 'integration-test' -->
      <phase>package</phase>
      <configuration>
        <target>
          <!-- delete existing mysql jar from appengine sdk lib/impl -->
          <delete>
            <fileset 
              dir="${settings.localRepository}/com/google/appengine/appengine-java-sdk/${appengine.target.version}/appengine-java-sdk/appengine-java-sdk-${appengine.target.version}/lib/impl" 
              includes="**/mysql-connector-java*" />
          </delete>
          <!-- copy mysql jar into appengine sdk lib/impl -->
          <copy 
            file="${settings.localRepository}/mysql/mysql-connector-java/${mysql.version}/mysql-connector-java-${mysql.version}.jar" 
            todir="${settings.localRepository}/com/google/appengine/appengine-java-sdk/${appengine.target.version}/appengine-java-sdk/appengine-java-sdk-${appengine.target.version}/lib/impl"/>
        </target>
      </configuration>
      <goals>
        <goal>run</goal>
      </goals>
    </execution>
  </executions>
</plugin> 

Antoine's suggestion modifies your m2 repository, which can cause other issues. 
 If you follow it, and you encounter other issues, please first remove the 
appengine artifacts from your local maven repository before filing a bug.

wow this is an old bug;
