在一個簡單的 archetype:webapp 項目上調用 mvn archetype:create-from-project 要求 Setting.xml

Question

我正在按照此說明了解maven原型。 在一個簡單的 webapp 項目上調用mvn archetype:create-from-project project 要求我在.m2目錄下有setting.xml文件。

不知道為什么要問，無法找到這背后的任何具體原因。沒有為任何本地項目創建任何文檔狀態。

如果您提供清晰的圖片，請幫助。 運行命令時附加錯誤。

任何幫助都會很棒。

Answer 1

settings.xml不是在安裝過程中創建的，這就是為什么您需要在C:\\Users\\Rajat Dobriyal\\.m2\\settings.xml下創建一個默認設置文件，內容如下：

    <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>
