Java maven assembly, creating multiple runnable jars with different dependencies

Question

I'm trying to create and swt app which can run on both windows and mac. I'm fairly new to java so have been researching the options to build a runnable jar for both windows and mac (with different dependencies)

So basically there is one main class and the only difference is that one app uses the swt org.eclipse.swt.win32.win32.x86_64 dependency and the other one the org.eclipse.swt.cocoa.macosx.x86_64 dependency.

I currently have the following maven assembly setting:

<build>
        <plugins>
            <plugin>
                <artifactId>maven-assembly-plugin</artifactId>
                <version>3.1.1</version>
                <configuration>
                    <archive>
                        <manifest>
                            <mainClass>com.connectingmedia.swttest.App</mainClass>
                        </manifest>
                    </archive>
                    <descriptorRefs>
                        <descriptorRef>jar-with-dependencies</descriptorRef>
                    </descriptorRefs>
                </configuration>
                
                <executions>
                    <execution>
                        <id>make-assembly</id> <!-- this is used for inheritance merges -->
                        <phase>package</phase> <!-- bind to the packaging phase -->
                        <goals>
                            <goal>single</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>

And my dependencies:

<dependencies>
    <dependency>
        <groupId>junit</groupId>
        <artifactId>junit</artifactId>
        <version>3.8.1</version>
        <scope>test</scope>
    </dependency>
    <dependency>
        <groupId>org.eclipse.swt</groupId>
        <artifactId>org.eclipse.swt.win32.win32.x86_64</artifactId>
        <version>4.3</version>
    </dependency>
</dependencies>

Now this works fine to create a windows executable jar. And I can change the dependency to the mac version of swt for the mac version of the jar. But It would be nice to create both at the same time. I found this questions for creating multiple runnable jars: Creating Two Executable Jars Using maven-assembly-plugin

But they use another main class and not different dependencies. <descriptorRef>jar-with-dependencies</descriptorRef> seems to always include all dependencies, or is there a way to select which one to use?

Anyway, The main question is: Am I going the right way to create a maven file that creates multiple runnable jars with different dependencies?
