Getting status of repository [message #1313288]

Hello.

I'm desperately trying to find a simple working example of JGit.
I found an example in the "jgit-cookbook" and changed it a little:

import java.io.File;
import java.io.IOException;

import org.eclipse.jgit.api.Git;
import org.eclipse.jgit.api.Status;
import org.eclipse.jgit.api.errors.GitAPIException;
import org.eclipse.jgit.lib.Repository;
import org.eclipse.jgit.storage.file.FileRepositoryBuilder;

public class Main {

	public static void main(String[] args) throws IOException, GitAPIException {
		FileRepositoryBuilder builder = new FileRepositoryBuilder();
		Repository repository = builder
				.setGitDir(
						new File(
								"....git")) // I'm not allowed to post links here
				.readEnvironment() // scan environment GIT_* variables
				.findGitDir() // scan up the file system tree
				.build();

		Status status = new Git(repository).status().call();
		System.out.println("Added: " + status.getAdded());
		System.out.println("Changed: " + status.getChanged());
		System.out.println("Conflicting: " + status.getConflicting());
		System.out.println("ConflictingStageState: "
				+ status.getConflictingStageState());
		System.out.println("IgnoredNotInIndex: "
				+ status.getIgnoredNotInIndex());
		System.out.println("Missing: " + status.getMissing());
		System.out.println("Modified: " + status.getModified());
		System.out.println("Removed: " + status.getRemoved());
		System.out.println("Untracked: " + status.getUntracked());
		System.out.println("UntrackedFolders: " + status.getUntrackedFolders());

		repository.close();
	}

}

But unfortunately I get the following error:

Exception in thread "main" org.eclipse.jgit.errors.NoWorkTreeException: Bare Repository has neither a working tree, nor an index
	at org.eclipse.jgit.lib.Repository.getWorkTree(Repository.java:1245)
	at org.eclipse.jgit.treewalk.FileTreeIterator.<init>(FileTreeIterator.java:88)
	at org.eclipse.jgit.api.StatusCommand.call(StatusCommand.java:126)
	at Main.main(Main.java:23)

I just want to get some simple information like name, date, size, etc. of all files. So I think, I need an iterator.

I'm no JGIt expert but the error message seems pretty clear: the file path you're providing is pointing at a bare repository, where the calls you're doing don't make any sense.
A bare repo can never have added, changed, untracked or removed files. It does't contain working all files at all. All it has are commits. You would get the same sort of error with standard Git if you ran 'git status' on a bare repository.

Try pointing at a clone instead.

Thank you!

I've edited my code, but still get the same error:

import java.io.File;
import java.io.IOException;

import org.eclipse.jgit.api.Git;
import org.eclipse.jgit.api.Status;
import org.eclipse.jgit.api.errors.GitAPIException;
import org.eclipse.jgit.lib.Repository;
import org.eclipse.jgit.storage.file.FileRepositoryBuilder;

public class Main {

	private static final String REMOTE_URL = "....git"; // a URL

	public static void main(String[] args) throws IOException, GitAPIException {

		File localPath = File.createTempFile("TestGitRepository", "");
		localPath.delete();

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

		FileRepositoryBuilder builder = new FileRepositoryBuilder();
		Repository repository = builder.setGitDir(localPath).readEnvironment()
				.findGitDir().build();

		Status status = new Git(repository).status().call();
		System.out.println("Added: " + status.getAdded());
		System.out.println("Changed: " + status.getChanged());
		System.out.println("Conflicting: " + status.getConflicting());
		System.out.println("ConflictingStageState: "
				+ status.getConflictingStageState());
		System.out.println("IgnoredNotInIndex: "
				+ status.getIgnoredNotInIndex());
		System.out.println("Missing: " + status.getMissing());
		System.out.println("Modified: " + status.getModified());
		System.out.println("Removed: " + status.getRemoved());
		System.out.println("Untracked: " + status.getUntracked());
		System.out.println("UntrackedFolders: " + status.getUntrackedFolders());

		repository.close();
	}

}
