爲什麼MVN乾淨安裝-U不工作：不可分辨父POM

Question

我已經從GitHub和問題克隆the repositorymvn clean install -U但由於某種原因，我得到：

[INFO] Scanning for projects... 
[ERROR] [ERROR] Some problems were encountered while processing the POMs:

我該如何解決這個問題？我實際上想更新我的本地存儲庫，因爲有一個我依賴的更新。我不記得我是如何安裝依賴關係的，但是當時我沒有得到這個錯誤。甚至在我身邊的錯誤？

Answer 1

那裏不是很棒的設計。您收到此錯誤的原因是gwt-material-addins依賴於SNAPSHOT版本gwt-material-parent，但該工件未部署在任何存儲庫中（在SNAPSHOT版本中）。

因此，您需要首先克隆並安裝gwt-material。這將在正確的SNAPSHOT版本中安裝gwt-material-parent，然後，您將能夠構建gwt-material-addins。

要回顧一下：

• 克隆https://github.com/GwtMaterialDesign/gwt-material
• 運行mvn clean install上gwt-material
• 然後在gwt-material-addins運行mvn clean install。
