Question

我正在尝试使用JGit API和以下代码进行git pull

public class gitHubTest {
    JSch jsch = new JSch();

    // Defining the private key file location explicitly
    String userHome = System.getProperty("user.home");
    String privateKey = userHome + "/.ssh/id_rsa";
    String knownHostsFile = userHome + "/.ssh/known_hosts";
    Repository localRepo = new FileRepository("/LocalPath/.git");

    public gitHubTest() throws Exception {
        jsch.setConfig("StrictHostKeyChecking", "no");
        jsch.setKnownHosts(knownHostsFile);
        jsch.addIdentity(privateKey);
        System.out.println("privateKey :" + privateKey);
        Git git = new Git(localRepo);
        PullCommand pullcmd = git.pull();
        pullcmd.call();
    }
}

错误堆栈跟踪：

我已经检查了一些建议，我们需要实例化JschConfigSessionFactory，然后重写configure（）方法来传递密码。我已经尝试过这样做了。然后它显示错误。我已经提到http://www.codeaffine.com/2014/12/09/jgit-authentication/，它读得恰到好处但不适合我的PullCommand。

有人可以帮忙吗？我已经在这里阅读并尝试过很多帖子，但没有一个能准确地解决我的问题。

使用configure（）方法实现代码：

public class gitHubTest {
JSch jsch = new JSch();
String userHome = System.getProperty("user.home");
String privateKey = userHome + "/.ssh/id_rsa";
String knownHostsFile = userHome + "/.ssh/known_hosts";

public gitHubTest() throws IOException, JSchException, GitAPIException {
    Repository localRepo = new FileRepository("/LocalPath/branch.git");
    final String remoteURL = "git@github.example.com:remote.git";
    JSch.setConfig("StrictHostKeyChecking", "no");
    jsch.setKnownHosts(knownHostsFile);
    jsch.addIdentity(privateKey);
    JschConfigSessionFactory sessionFactory = new JschConfigSessionFactory() {
    @Override
    protected void configure(OpenSshConfig.Host host, Session session) {
        CredentialsProvider cp = new CredentialsProvider() {
            @Override
            public boolean isInteractive() {
                return false;
            }
            @Override
            public boolean supports(CredentialItem... credentialItems) {
                return false;
            }
            @Override
            public boolean get(URIish urIish, CredentialItem... credentialItems) throws UnsupportedCredentialItem {
                return false;
            }
        };
        UserInfo userInfo = new CredentialsProviderUserInfo(session,cp);
        session.setUserInfo(userInfo);
    }
    };
SshSessionFactory.setInstance(sessionFactory);
Git git = new Git(localRepo);
PullCommand pullcmd = git.pull();
pullcmd.call();
}}

这会产生同样的错误。

我可以弄清楚我面临的一些问题。这是解决方案：

如果必须在没有密码短语的情况下进行身份验证，请生成不带密码短语的id_rsa

我们需要在配置SshSessionfactory时覆盖getJSch(final OpenSshConfig.Host hc, FS fs)使用addIdentity：

SshSessionFactory sshSessionFactory = new JschConfigSessionFactory() {
    @Override
    protected void configure(OpenSshConfig.Host host, Session sess ion) {
        session.setConfig("StrictHostKeyChecking", "no");
    }

    @Override
    protected JSch getJSch(final OpenSshConfig.Host hc, FS fs) throws JSchException {
        JSch jsch = super.getJSch(hc, fs);
        jsch.removeAllIdentity();
        jsch.addIdentity("/path/to/private/key");
        return jsch;
    }
};

我们需要以不同的方式调用需求：

PullCommand pull = git.pull().setTransportConfigCallback(new TransportConfigCallback() {

    @Override
    public void configure(Transport transport) {
        SshTransport sshTransport = (SshTransport) transport;
        sshTransport.setSshSessionFactory(sshSessionFactory);
    }
});

然后调用pull实例：

PullResult pullResult = pull.call();

我希望这会有所帮助。
