IntelliJ IDEA：设置SFTP服务器时的ArrayIndexOutOfBoundsException

Question

我似乎无法在IntelliJ IDEA中设置SFTP连接以进行部署。每当我尝试连接到服务器时，我都会得ArrayIndexOutOfBoundsException。在设置FTP服务器时，我没有得到这个例外，一切似乎都正常。

服务器可以访问，我仔细检查了我的登录详细信息......

有谁知道如何解决这个问题？

感谢CrazyCoder指出idea.log文件。我只是在“事件日志”中四处看看，这很空： - ）

当我添加日志文件时，我发现以下异常：

我的known_hosts文件（Error during processing known-hosts file "/Users/Robert/.ssh/known_hosts"）似乎有问题。我备份并删除它，现在一切似乎都运行良好。我只需查看哪一行是时髦的，因为ssh和sftp实用程序在终端内工作得很好，并且不会抱怨我的known_hosts文件。< / p>

希望这对其他有同样错误的人来说很方便。
