<plugins>
<!-- 指定启动类,将依赖打成外部jar包 -->
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<configuration>
<archive>
<!-- 生成的jar中,不要包含pom.xml和pom.properties这两个文件 -->
<addMavenDescriptor>false</addMavenDescriptor>
<manifest>
<!-- 是否要把第三方jar加入到类构建路径 -->
<addClasspath>true</addClasspath>
<!-- 外部依赖jar包的最终位置 -->
<classpathPrefix>lib/</classpathPrefix>
<!-- 项目启动类 -->
<mainClass>com.example.hanggedemo.HanggeDemoApplication</mainClass>
</manifest>
</archive>
</configuration>
</plugin>
<!--拷贝依赖到jar外面的lib目录-->
