mvn clean 命令错误 [关闭]

Question

我是 maven 新手，经过几年的编程，主要是 Ruby 和 JS，我又回到了 Java。

我刚开始玩 Maven，当我运行 mvn clean 时出现以下错误（我在 OS X El-Capitan 10.11.6 上运行）：

[INFO] Scanning for projects...

POM 文件：

<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">

    <artifactId>HelloWorld</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <modelVersion>4.0.0</modelVersion>
    <packaging>jar</packaging>

    <dependencies>
        <dependency>
            <groupId>commons-lang</groupId>
            <artifactId>>commons-lang</artifactId>
            <version>2.6</version>
        </dependency>
    </dependencies>
</project>

我一直在努力寻找答案，但在路上挣扎。

Answer 1

<artifactId>**>**commons-lang</artifactId>你这行有一个>太多

Answer 2

artifactId 中的额外 > 会给您带来问题。
