java代码中svngit svn 如何判断目录是否存在

在Java代码中，可以使用SVNKit或JGit库来操作SVN和Git版本控制系统。下面是使用SVNKit和JGit判断目录是否存在的示例代码：

使用SVNKit判断SVN目录是否存在的代码示例：

import org.tmatesoft.svn.core.SVNException;
import org.tmatesoft.svn.core.SVNURL;
import org.tmatesoft.svn.core.internal.io.dav.DAVRepositoryFactory;
import org.tmatesoft.svn.core.wc.SVNClientManager;

public class SVNExample {
    public static void main(String[] args) {
        // 初始化SVN库
        DAVRepositoryFactory.setup();

        String svnUrl = "svn://example.com/svn/repository";
        String svnDirectory = "/path/to/directory";

        try {
            SVNURL url = SVNURL.parseURIEncoded(svnUrl);
            SVNClientManager clientManager = SVNClientManager.newInstance();
            boolean directoryExists = clientManager.getWCClient().doInfo(url.appendPath(svnDirectory, false), null).getKind().isDirectory();
            
            if (directoryExists) {
                System.out.println("The directory exists.");
            } else {
                System.out.println("The directory does not exist.");
            }
        } catch (SVNException e) {
            e.printStackTrace();
        }
    }
}

使用JGit判断Git目录是否存在的代码示例：

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

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

public class GitExample {
    public static void main(String[] args) {
        String gitDirectory = "/path/to/repository";

        try {
            Repository repository = FileRepositoryBuilder.create(new File(gitDirectory));
            Git git = new Git(repository);
            boolean directoryExists = repository.getDirectory().exists();

            if (directoryExists) {
                System.out.println("The directory exists.");
            } else {
                System.out.println("The directory does not exist.");
            }
        } catch (IOException | GitAPIException e) {
            e.printStackTrace();
        }
    }
}
