在简单的 archetype:webapp 项目上调用 mvn archetype:create-from-project 要求 Setting.xml

Question

我正在按照此说明了解maven原型。调用mvn archetype:create-from-project一个简单的 webapp 项目，要求我setting.xml在.m2dir下有文件。

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

如果您提供清晰的图片，请帮助。运行命令时附加错误。

任何帮助都会很棒。

Answer 1

settings.xml不是在安装过程中创建的，这就是为什么你需要在下面创建一个默认设置文件的C:\Users\Rajat Dobriyal\.m2\settings.xml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>
