Create multiple runnable Jars (with dependencies included) from a single Maven project [duplicate]

You can do it. You’ll need a separate execution for each artifact that you’re building (i.e., give each its own id but you can leave the phase as default), and you’ll need to specify the finalName and archive/manifest/mainClass for each.

<build>
<plugins>
    <plugin>
        <artifactId>maven-assembly-plugin</artifactId>
        <executions>
          <execution>
            <id>build-a</id>
            <configuration>
              <archive>
                <manifest>
                  <mainClass>foobar.Aclass</mainClass>
                </manifest>
              </archive>
              <descriptorRefs>
                <descriptorRef>jar-with-dependencies</descriptorRef>
              </descriptorRefs>
              <finalName>foobar_a.jar</finalName>
            </configuration>
          </execution>
          <execution>
            <id>build-b</id>
            <configuration>
              <archive>
                <manifest>
                  <mainClass>foobar.Bclass</mainClass>
                </manifest>
