java - 使用 'sbt new playframework/play-java-seed.g8' 创建新项目 java 项目时无法正常工作并出现错误

Question

我刚刚开始学习框架教程。当我尝试使用 sbt new playframework/play-java-seed.g8 命令创建新的 java 项目时，在我的 Windows 计算机中安装了 SBT，出现以下错误。请帮助我理解并解决这个问题。请教如何使用java和play开始新项目。

您的系统中似乎没有安装 git bash。尝试安装 git( https://git-scm.com/downloads ) 并尝试再次运行相同的命令。这对我来说很有效。
