## 1、问题 ##

今天使用Jenkins构建部署服务时，报了如下错误：

[INFO] ------------------------------------------------------------------------
    [INFO] BUILD FAILURE

关键错误提示，其实是：

> **org.springframework.boot:spring-boot-maven-plugin:2.2.5.RELEASE:repackage failed: Unable to find a single main class from the following candidates**

## 2、解决方式 ##

**原因:**项目类，**我写了一个测试的main方法，导致Jenkins构建时，不知道使用哪个main方法**。因为springboot项目，本身也是有一个main方法的。

**解决：把自己写的main方法注释掉，或直接删除掉，就可以啦！**
