Maven無法使用原型：如果本地存儲庫已從.m2更改生成，則生成

我正面臨一個奇怪的問題。我編輯了M2_HOME/conf中的Maven settings.xml文件，並希望將這些jar下載到除{users.home}/.m2以外的其他位置。Maven無法使用原型：如果本地存儲庫已從.m2更改生成，則生成

我已將<localRepository>G:/m2Repo</localRepository>粘貼到settings.xml。

現在，當我鍵入mvn archetype:generate，我得到以下錯誤：

可能是什麼問題呢？

如果工件或元數據損壞，可能會發生這種情況。嘗試通過刪除所有版本的maven-archetype-plugin（，包括元數據和pom文件）來清理本地回購。然後再執行archetype:generate。

該問題已通過在settings.xml中刪除localRepository項來解決。開始再次生成原型將下載的工件移動到我們想要的地方G：/ m2Repo 開始再次生成工件。現在罈子等會自動下載到新的地方

我能想到的問題是我已經刪除了{users.home} /。m2文件夾也是阻止下載。

我的錯誤是：

（http://mirrors.ibiblio.org/pub/mirrors/maven2）：

Plugin not found in any plugin repository

解決方案：

1. go to .m2 folder > repository 
2. delete all folders inside this 
3. try the following command again: 

mvn archetype:generate
