idea报错：Failed to execute goal org.codehaus.mojo:execmavenplugin:3.0.0:exec (defaultcli) on

• idea版本：2020.3
• idea 报错：在查阅了资料以后发现是IDEA2020的兼容问题

Failed to execute goal org.codehaus.mojo:exec-maven-plugin:3.0.0:exec (default-cli) on project sms: Command execution failed.

• 解决方法：

1. 测试不要用main方法测试，使用junit测试
2. 更换版本至IDEA2017
3. File ->Settings -> Build, Execution, Deployment -> Build Tools -> Maven -> Runner
   取消将IDE生成/运行操作委托给Maven
