我遵循了两套指示：
https://www.spigotmc.org/wiki/cloning-building-and-compiling-the-spigot-source/
https://hub.spigotmc.org/stash/projects/SPIGOT/repos/spigot/browse/README.md
但我的问题出现在这一行之后：
git submodule update --init
根据说明，在我运行上述命令后，我需要“等待它完成下载”，除了没有下载。它只是在按Enter键后立即返回，完全没有消息。
我搜索了一些关于“git submodule update --init”如何返回空白，但我似乎无法将这些知识应用于我的情况。
这是我的终端输出：
