尝试使用java git库初始化git存储库

Question

我正在尝试创建一个目录，并使用javagit库将其初始化为git存储库。下面是我使用的代码片段：

repositoryDirectory = FileUtilities.createTempDirectory("C:/Madhu/ReleaseManagerRepo/Demo_gitRepository");
System.out.println("Git Repository Location : " + repositoryDirectory.getAbsolutePath());
//get the instance of the dotGit Object
dotGit = DotGit.getInstance(repositoryDirectory);
System.out.println("DotGit==========="+dotGit.toString());
//Initialize the repository ,similar to git init
dotGit.init();

我可以看到该目录已创建。在执行dotGit.init()之后，我看不到.git (当我从命令行运行命令git init时得到的)。在代码中指定的目录下的。

我的第二个问题是，我正在尝试从我的代码创建一个文件，并希望将其添加到git存储库。下面是相同的代码片段：

File file = FileUtilities.createFile(repositoryDirectory, "README", "First file in the git repository");

//get the current working tree from the git repository
WorkingTree wt = dotGit.getWorkingTree();
GitAddResponse ar = wt.add();
wt.commitAll("First commit to the git repository");

我得到一个异常，如下所示：

Exception in thread "main" java.io.IOException: 020100: Unable to start sub-process.

    ... 6 more

但我仍然看到了同样的例外。

你能建议一下。

问候你，马德胡丹。

死发布，但我刚刚通过将git path添加到系统环境变量中解决了同样的问题-- article
