一、报错内容

Failed to execute goal org.springframework.boot:spring-boot-maven-plugin:2.6.11:repackage (repackage) on project analyze: Execution repackage of goal org.springframework.boot:spring-boot-maven-plugin:2.6.11:repackage failed: Unable to find a single main class from the following candidates [com.xxx.analyze.LuckyLogAnalyzeApplication, com.xxx.analyze.consumer.FlinkESTest]

二、报错说明

因为LuckyLogAnalyzeApplication 和 FlinkESTest两个类中都有main方法，Maven找到了多个，所以在执行mave install的时候，报了上面的错误。

三、报错解决

直接删掉其中一个类，问题解决！
