BUILD FAILED in 606ms

首先我检查Gitlab上的SSH key有没有配置，发现没有配置，于是我一顿操作:
双引号里面填写gitlab的登录用户名

ssh-keygen -t rsa -C "your.email@example.com" -b 4096

一顿enter，y覆盖原有的公钥。
复制公钥到剪贴板，然后放到Key那个输入框里面，保存完事儿。

pbcopy < ~/.ssh/id_rsa.pub

可能有延迟一般10分钟后，邮件收到已经新增或者修改了SSH key,然后我一顿clone 还是不行，报错依旧。
解决办法：
ssh-keygen -m PEM -t rsa 重新生成旧格式的key，便可解决
-m 参数指定密钥的格式，PEM（也就是RSA格式）是之前使用的旧格式。然后再重复上线的复制ssh-rsa开头的公钥到gitlab的SSH里面填入，再次clone,正常了。。。
