I am having the Geritt GitHub Url : HTTPS -> ://mycompany.com/gerrit/p/my-services.git

I cloned via terminal it is working fine : git clone HTTPS -> ://mycompany.com/gerrit/p/my-services.git.

When I use the java code to clone using JGit , It is throwing error like "UnknownHostException",

I am wondering when I clone in terminal it is working fine, But When I try it with JGit , it is throwing error ? Why it is not recognizing that domain on JGit ?

Error log is,

org.eclipse.jgit.api.errors.TransportException: https -> ://mycompany.com/gerrit/p/my-services.git: cannot open git-upload-pack

My code is,

// I am using the below code to trust all the https urls,

// Create a trust manager that does not validate certificate chains
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();

I am usign the dependency

<dependency>
<groupId>org.eclipse.jgit</groupId>
<artifactId>org.eclipse.jgit</artifactId>
<version>3.0.0.201306101825-r</version>

</dependency>

Why it is not recognizing that domain on JGit ?

- maybe you need some proxy configuration ?
- instead of using your own TrustManager you could configure http.sslVerify = false in order to instruct jgit to trust all certs
- you are not using the latest jgit release, though 3.0 should work

Hi Matthias Sohn,

I specified the http.sslVerify = false in Bash profile. May I know the what kind of configuration that I have to specify ? . Code level idea is highly appreciated.

Hi Matthias Sohn,

Your suggestion guided me to find the solution. I need to set the proxy configuration in Jgit,

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.");
}
}
});

JGit doesn't look into the bash profile, it loads the git configuration from the usual git config files [1]:
* system level located at <native git installation path>/etc/gitconfig
* user level located at ~/.gitconfig
* repository level located at /path/to/repo/.git/config

In addition you can tweak the configuration programmatically using class FileBasedConfig.

Hello, I come to ask for help in a research project I am working. My algorithm makes analysis of refactoring between versions of projects
software written in java language. For that I need to test the tool with several projects. My choice was between test versions of projects
exposed on github. For this, we developed an algorithm communicates with the api git. Use the egit and JGit, but currently the algorithm
captures only link by .git download link. How could I do to download several projects going .git? Example of my code:

String urlGit="github.com/centic9/jgit-cookbook.git";
File localPath = File.createTempFile("GitRepository", "", new File("C:/GitHub"));
downloadgit.specificDownload(localPath, urlGit);
..............

protected void specificDownload(File path, String url) throws Exception {
Git.cloneRepository()
.setDirectory(path)
.setURI(url)
.setBare(false)
.setCloneAllBranches(true)
.call();
}
