我已从github克隆the repository并发出mvn clean install -U但由于某种原因我得到了：

如何解决此错误？我实际上想要更新我的本地存储库，因为有一个我依赖的更新。我不记得我是如何在第一时间安装依赖项的，但当时我没有得到这个错误。错误甚至在我身边吗？
答案 0 :(得分：0)
那里不是很棒的设计。您收到此错误是因为gwt-material-addins依赖于gwt-material-parent的SNAPSHOT版本，但该工件未部署在任何存储库中（在SNAPSHOT版本中）。
因此，您需要首先克隆并安装gwt-material。这将在正确的SNAPSHOT版本中安装gwt-material-parent，然后您就可以构建gwt-material-addins。
回顾一下：
https://github.com/GwtMaterialDesign/gwt-material mvn clean install gwt-material
mvn clean install上运行gwt-material-addins。
