java - Maven:不可解析的 POM

Question

我创建了一个 maven project现在我需要将依赖项添加到我的动态 web 项目。 所以我添加了在 spring tutorial 中命名的依赖项.

问题:我遇到了解析问题:

Project build error: Non-parseable POM C:\Users\username\Development\Spring\Projects\MyWebService\pom.xml: Duplicated tag: 'build' (position: START_TAG seen ...\r\n \r\n \r\n ... @60:10)

我的 pom.xml 看起来像这样:

eclipse 标记那一行:

问题:为什么在 pom.xml 中有多个存储库是错误的？

注意:Maven版本

Name: EMPEDDED, Details: 3.3.9/1.7.0.20160603-1931 - for Name: WORKSPACE, Details: NOT AVAILABLE [3.0,) 

Answer 1

我看到在您的错误中有 \r\n\r\n\r\n。

能否请您确保您的 pom.xml 正确编码为 UTF-8 而不是 ANSI？
