git - 如何使用带有 ssh 的 java api 推送到 gitlab

Question

我正在使用版本 GitLab Community Edition 9.1.1 d3123f6 的 gitlab。
我可以使用 http 协议(protocol)将我的代码推送到 gitlab，但是当我尝试使用 git 协议(protocol)时，它显示以下错误。

Exception in thread "main" 
org.eclipse.jgit.errors.UnsupportedCredentialItem: 
ssh://git@192......: 
org.eclipse.jgit.transport.CredentialItem$YesNoType:The authenticity 
of host '192......' can't be established.

RSA key fingerprint is 
99:...............
Are you sure you want to continue connecting?

我的代码是

private static final String REMOTE_URL = "git@192.....:ash/test.git";
File localPath = new File("/home/user/Git", "");
localPath.getParentFile().mkdirs();
localPath.createNewFile();
if(!localPath.delete()) {
    throw new IOException("Could not delete temporary file " + localPath);
}

Git git = Git.cloneRepository()
        .setURI( REMOTE_URL )
        .setDirectory(localPath)
        .setCredentialsProvider( cp )
        .call();
System.out.println("Cloning from " + REMOTE_URL + " to " + localPath);


System.out.println("please edit the file and then press \"Enter\" here to push ");
System.in.read();


File file = new File( git.getRepository().getWorkTree(), "file" + new Object().hashCode() );

git.add().addFilepattern( file.getName() ).call();

git.commit().setAll(true).setMessage("a message").call();

git.push() .setCredentialsProvider( cp ) .call();

System.out.println("Pushed from repository: " + localPath + " to remote repository at " + REMOTE_URL);

Answer 1

首先尝试从命令行建立连接:

ssh git@...

那应该问你同样的问题:回答'y'。

一旦完成，意味着一次 ~/.ssh/known_hosts已通过远程服务器的键扫描更新，您可以再次尝试相同的 Java JGit 程序。

我之前(5年前)发布过 a solution, but for EGit, not JGit .

在“ JGit Authentication Explained”查看更多信息

JGit provides an abstract JSchConfigSessionFactory that uses JSch to establish SSH connections and requires its configure() to be overridden

OP Ash添加 in the comments :

The problem was in .ssh/config file where needed lines are commented including private key identity.
