java maven工程打出可执行jar包，在pom.xml中添加如下配置即可
<build>
    <plugins>
        <!-- 设置编译版本 -->
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>

            </configuration>

        <!--可运行jar包-->
        <!--maven-jar-plugin的作用是配置mainClass和指定classpath。-->
        <plugin>

                        <addClasspath>true</addClasspath>
                        <!--指定类路径前缀，也就是依赖的jar包所在的文件夹-->
                        <classpathPrefix>lib/</classpathPrefix>
                        <!--指定启动类-->
