我有 Geritt GitHub 网址：https ://mycompany.com/gerrit/p/my-services.git

我通过终端克隆它工作正常：git clone https://mycompany.com/gerrit/p/my-services.git

当我使用 java 代码使用 JGit 进行克隆时，它会抛出类似“ UnknownHostException ”的错误，

我想知道当我在终端中克隆时（https://mycompany.com/gerrit/p/my-services.git）它工作正常，但是当我用 JGit 尝试它时，它会抛出错误吗？为什么它不能识别 JGit 上的域？

错误日志是，

我的代码是，

// 我使用下面的代码来信任所有的 https url，

// 创建一个不验证证书链的信任管理器

TrustManager[] trustAllCerts = new TrustManager[] { 
    new X509TrustManager() {     
        public java.security.cert.X509Certificate[] getAcceptedIssuers() { 
            return null;
        } 
        public void checkClientTrusted( 
            java.security.cert.X509Certificate[] certs, String authType) {
            } 
        public void checkServerTrusted( 
            java.security.cert.X509Certificate[] certs, String authType) {
        }
    } 
}; 

// Install the all-trusting trust manager
try {
    SSLContext sc = SSLContext.getInstance("SSL"); 
    sc.init(null, trustAllCerts, new java.security.SecureRandom()); 
    HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
} catch (GeneralSecurityException e) {

}


String url = "https://mycompany.com/gerrit/p/my-services.git";
String username = "username";
String password = "password";
String checkoutLocation = "/Users/testing";
String branch = "my-services-sample-test";

UsernamePasswordCredentialsProvider userCredential = new UsernamePasswordCredentialsProvider(username, password);
Git r = Git.cloneRepository().setDirectory(new File(checkoutLocation + "/clonned"))
.setCredentialsProvider(userCredential)
.setURI(url)
.setProgressMonitor(new TextProgressMonitor())
.setBranch(branch)
.call();
System.out.println("Clonning @ " + checkoutLocation);
r.getRepository().close();

我正在使用依赖项

我得到了解决方案。一位 Eclipse 社区成员给了我一些关于它的想法。

这是那个线程： http: //www.eclipse.org/forums/index.php/m/1176786/#msg_1176786

ProxySelector我需要使用该类为 JGit 设置代理配置。

ProxySelector.setDefault(new ProxySelector(){
    final ProxySelector delegate = ProxySelector.getDefault();

    @Override
    public List<Proxy> select(URI uri) {
        // Filter the URIs to be proxied

        if (uri.toString().contains("github") && uri.toString().contains("https")) {
            return Arrays.asList(new Proxy(Type.HTTP,
              InetSocketAddress.createUnresolved("localhost", 3128)));
        }
        if (uri.toString().contains("github") & uri.toString().contains("http")) {
            return Arrays.asList(new Proxy(Type.HTTP,
              InetSocketAddress.createUnresolved("localhost", 3129)));
        }

        // revert to the default behaviour
        return delegate == null ? Arrays.asList(Proxy.NO_PROXY) : delegate.select(uri);
    }

    @Override
    public void connectFailed(URI uri, SocketAddress sa, IOException ioe) {
        if (uri == null || sa == null || ioe == null) {
            throw new IllegalArgumentException("Arguments can't be null.");
        }
    }
});

就我而言"localhost"/3128，localhost"/3129分别是我想使用的 HTTPS 和 HTTP 代理 URL/端口。

参考：代码中的 JGit 代理配置

它运作良好。
