Maven打包时指定Main函数，生成可执行jar包

 <build>    <plugins>      <plugin>        <groupId>org.apache.maven.plugins</groupId>        <artifactId>maven-jar-plugin</artifactId>        ...        <configuration>          <archive>            <manifest>              <addClasspath>true</addClasspath>              <mainClass>fully.qualified.MainClass</mainClass>            </manifest>          </archive>        </configuration>        ...      </plugin>    </plugins>  </build>
