检查结束构建标记 </build>>。

有一个额外的 > 被解释为文本。

我认为编辑器应该抱怨这个，但它没有，在我的 Eclipse 中没有。

更新:编辑愉快接受的原因是我只是复制粘贴了你的pom。

您有：

<project>

在您的 pom 开头。

它应该是这样的：

<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/xsd/maven-4.0.0.xsd">

schemaLocation 告诉编辑器如何验证并告诉您这些错误。

添加它并查看您的编辑器是否在构建之前发现问题。
