Maven：项目构建错误“modelVersion”丢失

Question

我正在尝试创建一个新的 Maven 项目，但我从 pom.xml 中收到此错误...

有人可以帮我解决这个问题吗？我是 Maven 和 Eclipse IDE 的新手

非常感谢。

Answer 1

您的

pom.xml

不完整

你需要

<?xml version="1.0" encoding="UTF-8"?>
<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">
    <modelVersion>4.0.0</modelVersion>
    <groupId>your.group.id</groupId>
    <artifactId>your-artifact-id</artifactId>
    <version>your-version</version>

<!-- all stuff here -->

</project>

这是到目前为止 POM.XML 文件的 xml 代码：

    <?xml version="1.0" encoding="UTF-8"?>
<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">
    <modelVersion>4.0.0</modelVersion>
    <artifactId>maven-examples</artifactId>
    <groupId>com.infiniteskills.maven</groupId>

我也遇到同样的问题..

我尝试附加相同的样式，并向我显示了一堆错误消息，如下所示：
