1、通过https://start.spring.io/快速创建一个Spring工程，添加依赖包含web和actuator。默认spring版本是2.1.6
2、使用idea打开工程，添加一个rest接口方法，用来测试工程。
3、打开teminal命令窗口，执行maven clean package -Dmaven.test.skip就开始报错：
最初报错为mvn不是内部或外部命令：解决方法，配置mvn环境变量
4、接着报错信息为（该问题好像重新创建了一遍工程就好了）：

4、接着报了另外一个错误：
Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.1:
compile (default-compile) on project springboot: Fatal error compiling:无效的参数.......
原因是，本地默认jdk版本是1.8，mvn使用的jdk版本是1.7，应该是两者jdk版本不一致导致的吧，反正将mvn使用的jdk修改成1.8就成功打包了。
