【问题描述】：

我正在关注 this instruction 以了解 maven 原型。 在一个简单的 webapp 项目上调用mvn archetype:create-from-project，要求我在.m2 目录下拥有setting.xml 文件。

不知道为什么要问，找不到任何具体的原因。没有为任何本地项目创建任何文档状态。

如果你给一个清晰的图片，请帮助。 在运行命令时附加错误。

任何帮助都会很棒。

【参考方案1】：

settings.xml不是在安装过程中创建的，所以你需要在C:\Users\Rajat Dobriyal\.m2\settings.xml下创建一个默认设置文件，内容如下：

    <settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0
                          https://maven.apache.org/xsd/settings-1.0.0.xsd">
    </settings>

更详细的是here

【讨论】：

谢谢。但它适用于 settings.xml 的原因是什么。即使在没有这样的配置之后。在看到任何教程时，甚至都没有提到 settings.xml
