How to add test-jar and jar as dependency in a maven multimodule project?

[Debraj Manna]

I have a maven multimodule project of the form

- main
  - storage
     - storage-config
     - storage-utils
     - storage-common
    - tools

I have a class `com.vnera.storage.config.Embedded.java` residing under test
folder in `storage-config` which I want to use in `storage-utils` under
`test` scope. `storage-utils` also needs `storage-config` in main phase.

I have added the below section in `storage-config` pom and I am seeing
`test-jar` of `storage-config` is getting generated.

    <plugin>
                    <groupId>org.apache.maven.plugins</groupId>
                    <artifactId>maven-jar-plugin</artifactId>
                    <version>2.4</version>
                    <executions>
                        <execution>
                            <goals>
                                <goal>test-jar</goal>
                            </goals>
                        </execution>
                    </executions>
                </plugin>

`storage-utils` pom looks like below

                            </goals>
                        </execution>
                    </executions>
                </plugin>
            </plugins>
        </build>
    </project>

My compilation is running fine. But whenever I am trying to access
 `Embedded.java` from a class in `storage-utils` in `test` scope. I am
getting `NoClassDefFoundError` for `Embedded.java`.

Can someone let me know what is going wrong and how can I solve this?
