我在项目的deps.edn文件中添加了一个git依赖项。
在尝试使用"clj"依赖项启动repl（安装依赖项）时，由于标题中提到的错误而失败。
构建类路径时出错。git@XXX:YYY/ZZZ.git: UnknownHostKey: XXX。RSA密钥指纹是YYYY

这个问题的原因似乎是在jgit中（如b6e2800560dbf7348dcc1965e9069863ef96e4f5所描述的）

当远程服务器支持ssh-rsa时，JSch偏好ssh-rsa密钥类型。
key type then this key type will be used even if the known_hosts file
contains a host key for that host, but with different key type.
This caused an unexpected UnknownHostKey error.

"""
上面的jgit提交可能希望解决这个问题。
tools.gitlibs仍然依赖于一个不包含这个提交的较旧版本的jgit。
因此，请依次更新tools.gitlibs和tools.deps.alpha中的jgit版本。
现在只有一个解决方案（显然，之前也有人遇到过这个问题）
https://codehopper.nl/2018/09/27/clojure-gitlab-deps/
基本原理：修改您的known_hosts和ssh-config-file，我认为这非常不好。
