我已经下载了scala源代码，正如自述文件所述，我可以使用IntelliJ编译代码。
/ src / IntelliJ下的README.md告诉我先运行“ sbt IntelliJ”
我多次运行此命令，但出现错误：
[error] Could not determine commit date + SHA: java.lang.IllegalArgumentException: One of setGitDir or setWorkTree must be called.

[错误]服务器错误：GATEWAY_TIMEOUT url
所有需要从repo.lightbend.com下载的文件失败
如何解决？
