Java 使用maven创建WAR文件时，已在类错误中定义了方法configure（org.springframework.boot.builder.SpringApplicationBuilder）

运行

mvn clean install

时出现以下错误：

编译失败：

c:\path\to\myfolder\application.java方法 配置（org.springframework.boot.builder.SpringApplicationBuilder） 已在类my.project.tree.myApplication中定义

我做错了什么？此时此刻，我不知道是什么导致了错误

向我们展示application.java和my.project.tree.myApplicationAh，让我们更清楚地了解application.java和myApplication似乎是同一个文件。
