我可以通过终端中的sftp命令连接到我的服务器，并且通过filezilla也可以正常工作。
但是当我在netbeans中尝试连接时，它失败了;输出:

我通过netbeans和sftp连接到其他服务器没有问题。
如何解决这个问题并连接到服务器?
这是因为您在服务器和客户端上没有任何通用的密钥交换方法:
kex: server: curve25519-sha256@libssh.org,diffie-hellman-group-exchange-sha256,diffie-hellman-group14-sha1
[…]
kex: client: diffie-hellman-group1-sha1,diffie-hellman-group-exchange-sha1
要解决这个问题，你需要允许一些传统的方法在服务器上使用KexAlgorithms选项在sshd_config或允许一些合理的方法在客户端(不确定如何在JSCH上做到这一点)。
