Maven - How to exclude dependencies from generated JAR

I have 3 projects that looks like this: enter image description here

The problem is that the common DB code has a converter class, and I am getting the below error while running the Business logic.

Caused by: org.hibernate.AssertionFailure: AttributeConverter class [class com.td.sba.iep.jpa.converters.ModeltoDBAttributeConverter] registered multiple times

What I did: I tried to exclude the dependencies while packaging the Utility classes using the below code in pom.xml.

            <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
            <!-- Fools the plugin into creating the code only jar instead of the runnable one -->
            <executions>
                <execution>
                    <goals>
                        <goal>repackage</goal>
                    </goals>
                    <configuration>
                        <classifier>exec</classifier>
                    </configuration>
                </execution>
            </executions>
        </plugin>

But when I include the exec jar created into the Business logic, it shows that the utility classes are not found.

WHAT I NEED: How do I fix the 'org.hibernate.AssertionFailure'? Should I exclude the dependencies while creating the jar from utility classes? How do I do it?

Incase it matters, I am using Eclipse.

Have you tried to use <exclusions> element on this project dependencies? Like:

Business Logic Project pom.xml file:

    <dependency>
        <groupId>com.utility.project</groupId>
        <artifactId>UtilityProject</artifactId>
        <version>1.0.0</version>
        <exclusions>
            <exclusion>
                <groupId>group.id.jar.you.want.to.exclude</groupId>
                <artifactId>artifact.id.jar.you.want.to.exclude</artifactId>
            </exclusion>
        </exclusions>
    </dependency>

UPDATE

Since you already have CommonDB dependencies on your UtilityProject pom, remove this CommonDB dependency from your business logic pom. This error is because you have 2 classes (same class) being registered with same name. If you already have CommonDB dependency on UtilityProject and you use this UtilityProject as dependency on Business, you don't need to import it twice.
