How to automatically collect all related class int

I have a class ClassA in package packageA and ClassA import ClassB in packageB.(in fact ClassA import a lot of java file)

Then the directory is ：

root
     pom.xml
     src 
             packageA
                      classA
                      pom.xml
             packageB
                      classB

My goal is to generate a jar include classA and classB by only telling maven that I input classA.

the pom.xml in the root directory is like

<groupId>org.abc</groupId>
<artifactId>all-code</artifactId>
<version>0.0.1-SNAPSHOT</version>
<packaging>pom</packaging>
<modules>
    <module>\src\packageA</module>
</modules>
<name>helloworld</name>

<dependencies>
    <dependency>
    </dependency>
</dependencies>

the pom.xml in the packageA directory is like

<parent>
    <relativePath>..\..\</relativePath>
    <artifactId>all-code</artifactId>
    <groupId>org.abc</groupId>
    <version>0.0.1-SNAPSHOT</version>
</parent>
<artifactId>client-code</artifactId>
<packaging>jar</packaging>
<version>0.0.1-SNAPSHOT</version>
<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-jar-plugin</artifactId>
            <version>2.3.1</version>
            <executions>
                <execution>
                    <id>client</id>
                    <phase>package</phase>
                    <goals>
                        <goal>jar</goal>
                    </goals>
                    <configuration>
                        <classifier>client</classifier>
                        <includes>
                            <include>packageB\*</include>
                        </includes>
                    </configuration>
                </execution>
            </executions>
        </plugin>                               <!--it doesn't work-->
    </plugins>
    <sourceDirectory>.</sourceDirectory>        <!--it works-->
</build>

And the error message is package does not exist

I read the question here and try it. Building a fat jar using maven And I think the link question is to achieve that the asker want to include external jars into one jar . But I want to include my own classB into one jar ,while I only input classA to maven ,and let maven find classB because classA import classB.

Finally I write a program myself to solve this problem
