【问题描述】：

我正在使用 JGit 连接到远程 Git 存储库。我尝试在下面执行相同的操作。

public class Main{
    public static void main(String args[]) throws Exception{
        JschConfigSessionFactory sshSessionFactory = new JschConfigSessionFactory() {
              @Override
              protected void configure( Host host, Session session ) {
                session.setPassword( "XXXX" );
              }
            };

            String REMOTE_URL="ssh://git@url/test.git";
            CloneCommand cloneCommand = Git.cloneRepository();
            cloneCommand.setURI( "ssh://git@url/test.git" );
            cloneCommand.setTransportConfigCallback( new TransportConfigCallback() {
              @Override
              public void configure( Transport transport ) {
                SshTransport sshTransport = ( SshTransport )transport;
                sshTransport.setSshSessionFactory( sshSessionFactory );
              }
            } );

            System.out.println("Listing remote repository " + REMOTE_URL);
            Collection<Ref> refs = Git.lsRemoteRepository()
                    .setHeads(true)
                    .setTags(true)
                    .setRemote(REMOTE_URL)
                    .call();

            for (Ref ref : refs) {
                System.out.println("Ref: " + ref);
            }
    }
}

错误：

Listing remote repository ssh://git@url/test.git

我浏览了互联网；发现需要添加以下内容：

com.jcraft.jsch.JSch.setConfig ( "StrictHostKeyChecking", "no" );

但是，在上面的代码 sn-p 中放置它的位置。是否有可用的示例工作代码 sn-p。

【问题讨论】：

您是否尝试在JschConfigSessionFactory 的实现中更改主机检查设置，即session.setConfig( "StrictHostKeyChecking", "no" );？
嗨 Rudiger，我已经把session.setconfig ( "StrictHostKeyChecking", "no" ); ssh 密钥错误消失了。我收到“身份验证错误”
嗨 Rudiger，请在下面找到代码/研究
您当然需要为远程存储库提供合适的凭据。请参阅此处了解更多信息：codeaffine.com/2014/12/09/jgit-authentication

【解决方案1】：

您可以使用 Session 对象调用 setConfig("","") 方法，如下所示：-

JSch jsch = new JSch();
Session session = jsch.getSession(username, hostname, 22);
session.setConfig("StrictHostKeyChecking", "no");
session.setPassword(password);
session.connect();

希望对您有所帮助。
