maven - 调用 mvn 原型(prototype) :create-from-project on a simple archetype:webapp project is asking for Setting. xml

Question

我正在关注 this instruction了解maven原型(prototype)。打电话mvn archetype:create-from-project在一个简单的 webapp 项目上要求我有 setting.xml .m2 下的文件目录。

不确定为什么要问，无法找到这背后的任何具体原因。也没有为任何本地项目创建任何文档状态。

如果能给个清晰的图片请帮忙看看。附加运行命令时的错误。

任何帮助都会很棒。

Answer 1

settings.xml 不会在安装过程中创建，这就是为什么您需要在 C:\Users\Rajat Dobriyal\.m2\settings.xml 下创建默认设置文件的原因> 内容:

    <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>
