我正在尝试将我的本地主机与 sshj 库提供的类连接起来，用于教育目的。所以我编写了上面的代码，但方法存在问题new SSHClient.authPublickey(String userName,KeyProvider... keys)。我跟踪了我的代码的每一行，不仅仅是我也跟踪的sshj库，但我不能找到任何有用的东西。我在下面的项目中提供错误代码、从我的 IDE( NetBeans 8.1) 生成的堆栈跟踪、我的源代码和导入的 jar。
Jar 文件：（由于 stackoverflow 信誉限制，我不能共享超过 2 个链接）
1. sshj-0.2.3.jar
2. slf4j-api-1.7.21.jar 链接 =二进制和源代码
3. bcprov,bcpkix,bcpg,bcmail(jdk 1.5 - 1.8 版本文件) 链接 =签名的 Jar 部分
源代码 ：
SSHClient sshClient = new SSHClient();
sshClient.addHostKeyVerifier(new PromiscuousVerifier());
sshClient.connect("localhost");
File keyFile = new File(dir);//dir = directory of publickey file
KeyProvider pubkey = sshClient.loadKeys(keyFile.getPath(),pass);//pass = passphrase of the pubkey file
sshClient.authPublickey(uName, pubkey); //error occuring in this line
错误代码 ：

堆栈跟踪行是 sshClient.authPublickey(uName, pubkey)
SSHClient.java 1. 分支
public void authPublickey(String username, KeyProvider... keyProviders)
throws UserAuthException,
TransportException {
authPublickey(username, Arrays.<KeyProvider>asList(keyProviders));
堆栈跟踪行是 authPublickey(username, Arrays.asList(keyProviders));
SSHClient.java 2. 分支
public void authPublickey(String username, Iterable<KeyProvider> keyProviders)
throws UserAuthException,
TransportException {
final List<AuthMethod> am = new LinkedList<AuthMethod>();
for (KeyProvider kp : keyProviders)
am.add(new AuthPublickey(kp));
auth(username, am);
身份验证（用户名，上午）；
SSHClient.java 3. 分支
public void auth(String username, Iterable<AuthMethod> methods)
throws UserAuthException, TransportException {
assert isConnected();
auth.authenticate(username, (Service) conn, methods);//exception thrown at this line
我已经用没有密码的 ssh-keygen 生成了我的 ssh 公钥，我也有密码保护的 pubkey。如果我用它尝试同样的事情，错误仍然是一样的。如果需要任何其他的东西我准备分享只是说出来。
