Gan*_*ana 8 java github egit jgit
*在此问题的底部添加了最终工作计划*
我能够使用org.eclipse.egit.github.core java库向GitHub添加一个文件(代码示例来自这里:https://gist.github.com/Detelca/2337731)
但我无法给出像"folder1\myfile.txt"或"folder1\folder2\myfile.txt"这样的路径
我试图找到一个简单的例子来添加文件夹下的文件,但实际上无法找到它.
有关此示例的任何帮助吗？
下面是我正在使用的代码:(配置详细信息,如用户名,reponame在方法addFileToGH()中)

以下是执行上述代码时的错误.

编辑:引发错误的代码被注释.注释的代码以"//代码添加文件夹,不工作"开头
可能的问题是这行代码:folderEntry.setSha(blob_sha);
此行引发错误: Tree newTree = dataService.createTree(repository,entries,baseTree.getSha());
编辑(VonC响应):您好VonC,非常感谢您的回复.JGit看起来很有希望,但我看到下面的问题.
你能参考创建文件夹的任何例子吗？我尝试下面的代码添加文件夹,但没有工作!
import java.io.File;
import java.io.IOException;
import java.io.PrintWriter;

import org.eclipse.jgit.lib.Repository;
public class GHFolderWriter {
public static void main(String[] args) throws IOException, NoFilepatternException, GitAPIException {
// prepare a new test-repository
try (Repository repository = CookbookHelper.createNewRepository()) {
try (Git git = new Git(repository)) {
//create folder
File folder = new File(repository.getDirectory().getParent(), "folder1");
if(!folder.createNewFile()) {
throw new IOException("Could not create folder " + folder);
}
// create the file
File myfile = new File(folder, "testfile1.txt");
if(!myfile.createNewFile()) {
throw new IOException("Could not create file " + myfile);
}
// Stage all files in the repo including new files
git.add().addFilepattern(".").call();
// and then commit the changes.
git.commit()
.setMessage("Commit all changes including additions")
.call();
try(PrintWriter writer = new PrintWriter(myfile)) {
writer.append("Hello, world!");
}
// Stage all changed files, omitting new files, and commit with one command
git.commit()
.setAll(true)
.setMessage("Commit changes to all files")
.call();
System.out.println("Committed all changes to repository at " + repository.getDirectory());
}
}
}
}
它抛出了这个错误:
线程"main"中的异常java.io.IOException:无法打开文件.原因:系统找不到指定的路径(路径C:\ Users\ramgood\AppData\Local\Temp\TestGitRepository441020326444846897\folder1\testfile1.txt,工作目录C:\ Users\ramgood\workspace-sapui5-1.32\accelerate)at java.io.WinNTFileSystem.createFileExclusively(Native Method)at java.io.File.createNewFile(File.java:1016)at com.apps.ui5.accelerator.writers.GHFolderWriter.main(GHFolderWriter.java:37)
编辑(3):我按照你的建议移动到jgit,下面是我的新程序.我能够1.使用我的本地仓库克隆远程仓库2.将文件夹和文件添加到本地仓库并在本地提交但是 3.无法推送到github.

我试图推送到远程repo或github时遇到错误.

感谢VonC的回复.
要操作 Git 存储库中的文件，您最好直接使用 JGit，而不是Egit-GitHub（尽管它基于 JGit）。
这样，您就可以从 中的示例中受益centic9/jgit-cookbook，包括jgit/porcelain/CommitAll.java使用以下示例addFilepattern：
// Stage all files in the repo including new files
git.add().addFilepattern(".").call();
这样，您就可以添加所需的任何文件夹（内容）。
我正在云实例中将其作为服务运行，我不知道是否可以依赖说明书示例中引用的 filerepo。如果这在云中有效，我可以考虑将其作为解决方案。
您将依赖您现在使用的相同文件存储库。
该示例还添加了一个简单的文件，但不是文件夹/目录。
只需用文件夹替换文件：它将起作用并添加文件夹内容。
我需要使用 java 程序而不是 git 命令将更改推送到 GitHub。我怎样才能做到这一点？
只需将远程添加到 GitHub 存储库并推送即可。
两者都可以在 JGit 中使用（在 Java 中也是如此）。
