I am creating a Spring Boot multi module project.. Module A has a dependency on Module B ..

Module A runs fine when I run in exploded form.. 

          mvn spring-boot:run

But I am unable to package the jar along with dependencies so that I can execute it as 

          java -jar Module-A.jar

Module A pom.xml is below:

 <parent>
    <artifactId>Module-Test</artifactId>
    <groupId>com.module</groupId>
    <version>1.0.0-SNAPSHOT</version>
</parent>
<modelVersion>4.0.0</modelVersion>

<artifactId>Module-A</artifactId>
<packaging>jar</packaging>

<properties>
    <start-class>com.NotifyApp</start-class>
    <main.class>com.NotifyApp</main.class>
</properties>

<dependencies>
    <dependency>
        <groupId>com.module</groupId>
        <artifactId>Module-B</artifactId>
        <version>${project.version}</version>
    </dependency>
</dependencies>

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

Which command do you execute and from which location ? - davidxxx
I am executing mvn clean install parallel inside Module-A directory (parallel to pom.xml) .. This is done on Intellij idea terminal - Tiny
Ok. You may have some issues from the parent pom. Can you show it ? - davidxxx
I have updated the question with the parent pom.xml - Tiny

I usually use this plugin https://maven.apache.org/plugins/maven-dependency-plugin/examples/copying-project-dependencies.html for maven, which will put all of the dependency jars into target/dependencies when you run

mvn clean package

Then I copy the jars into a folder (which I usually call lib) and I include lib/* in my classpath. The final run script usually looks like 

java -cp lib/*: my.package.MySpringBootMain

Remove the 

<executions>
            <execution>
                <goals>
                    <goal>repackage</goal>
                </goals>
            </execution>
        </executions>

It's not needed.

Add dependency of module B in module A's pom.xml

<dependencies>
    <dependency>
        <groupId>com.module</groupId>
        <artifactId>Module-B</artifactId>
        <version>${project.version}</version>
    </dependency>
</dependencies>

<build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
        </plugin>
    </plugins>
</build>

Use maven clean compile package install command for module B, to build module B first and then run maven clean compile package on Module A. This will out Module B into Module A.

There is no module A's reference required in Module B's pom.xml

you sure know, but you can initialize your project from this link Spring Initializr , it automatically generates the configuration with what you need
