二.错误原因

因为没有正式环境的入口类,项目结构如下:

repackage failed: Unable to find main class

pom.xml文件的配置信息如下:

repackage failed: Unable to find main class

三.解决方案1

pom.xml文件的中指定入口类,代码如下

    com.qfx.App

如图

repackage failed: Unable to find main class

四.解决方案2

去掉配置信息中spring热部署的配置，如图

repackage failed: Unable to find main class

五.解决方案3

修改pom.xml配置文件内容如下,添加一个标签，代码如下

    test

    

        

            

                org.springframework.boot

                spring-boot-maven-plugin

                

                    

                    

                        org.springframework

                        springloaded

                        1.2.8.RELEASE

                    

                

            

        

    

六.再次执行 Maven install,一切正常
