You should make use of the maven-jar-plugin to package your jarfile and provide a main class:

<build>
    <plugins>
        <!-- ... other plugins ... -->
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-jar-plugin</artifactId>
            <version>3.1.1</version>
            <configuration>
                <archive>
                    <manifest>
                        <!-- Your main class -->
                        <mainClass>sims_for_import.Main</mainClass>
                    </manifest>
                </archive>
            </configuration>
        </plugin>
    </plugins>
</build>

You can see the listing of the latest available plugin versions on the maven central repository.
