我的pom.xml与链接中列出的相同。任何帮助将受到高度赞赏。

Answer 1

请按照示例中给出的第2步进行操作。然后它应该工作。

删除示例附带的pom.xml文件中的父条目。删除父条目后，pom.xml文件的内容将类似于以下内容。或者，使用以下代码段替换pom.xml文件的内容。

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
