SpringBoot項目maven指令打包時報錯

錯誤如下：

Unable to find a single main class from the following candidates
           

詳細如下：

Failed to execute goal org.springframework.boot:spring-boot-maven-plugin:2.2.0.M4:repackage (default) on project demo-rpc-server: Execution default of goal org.springframework.boot:spring-boot-maven-plugin:2.2.0.M4:repackage failed: Unable to find a single main class from the following candidates [com.hello.demo.rpc.server.DemoServerStarter, com.hello.demo.rpc.server.common.testMain] -> [Help 1]
           

原因就是項目中除了啟動類的main之外還有一個我自己寫的測試類testMain,把自己的測試主類注釋或删除就好了。
