git jGit - 如何将所有文件添加到暂存区

jGit - how to add all files to staging area

提问by caarlos0

I tried in a lot of ways to clone a repo with jGit (it works). Then, I write some archive in the repository, and tried to add all (a git add *, git add -Aor something like it).. but it don't work. The files simple are not added to the staging area.

我尝试了很多方法来使用 jGit 克隆一个 repo（它有效）。然后，我写的一些库存档，并尝试添加所有（一个git add *，git add -A或者类似的东西）..但它不工作。文件 simple 不会添加到暂存区。

My code is like this:

我的代码是这样的：

    FileRepositoryBuilder builder = new FileRepositoryBuilder();
    Repository repository = builder.setGitDir(new File(folder))
            .readEnvironment().findGitDir().setup().build();
    CloneCommand clone = Git.cloneRepository();
    clone.setBare(false).setCloneAllBranches(true);
    clone.setDirectory(f).setURI("[email protected]:test.git");
    try {
        clone.call();
    } catch (GitAPIException e) {
        e.printStackTrace();
    }
    Files.write("testing it...", new File(folder + "/test2.txt"),
            Charsets.UTF_8);
    Git g = new Git(repository);
    g.add().addFilepattern("*").call();

What am I doing wrong? Thanks.

我究竟做错了什么？谢谢。

Exception while trying what with addFilePattern("."):

尝试使用 addFilePattern(".") 时出现异常：

Exception in thread "main" org.eclipse.jgit.errors.NoWorkTreeException: Bare Repository has neither a working tree, nor an index

One easy way to debug this is to look at the tests of the AddCommandin the JGit repo: AddCommandTest.java

一个简单的方法来调试这是看的测试AddCommand在JGit回购：AddCommandTest.java

You will see that in order to add all files the pattern "*" is never used, but "." is.
And it is used in the test function named... testAddWholeRepo()(!)

您将看到，为了添加所有文件，*从不使用模式“ ”，而使用“ .”。
它用于名为...的测试函数中testAddWholeRepo()（！）

git.add().addFilepattern(".").call();

The Exception:

例外：

Exception in thread "main" org.eclipse.jgit.errors.NoWorkTreeException: 
Bare Repository has neither a working tree, nor an index

is quite explicit: you need to add file in a non-bare repo.

非常明确：您需要在非裸存储库中添加文件。

See test method testCloneRepository()to compare with your own clone, and see if there is any difference.

查看测试方法testCloneRepository()与您自己的克隆进行比较，看看是否有任何差异。

I had a situation where I had to move a file f1 from the current directory to another directory called 'temp'. After moving the file, calling git.add().addFilePattern(".").call() acted in a weird way since git status gave the following result:

我遇到了一种情况，我不得不将文件 f1 从当前目录移动到另一个名为“temp”的目录。移动文件后，调用 git.add().addFilePattern(".").call() 的行为很奇怪，因为 git status 给出了以下结果：

Changes to be committed:
  (use "git reset HEAD <file>..." to unstage)

    new file:   temp/f1.html

Changes not staged for commit:
  (use "git add/rm <file>..." to update what will be committed)
  (use "git checkout -- <file>..." to discard changes in working directory)

    deleted:    f1.html

It recognized that a new file temp/f1 was created but didn't detect that the file was deleted first. This was perhaps because moving the file can be seen as follows

它识别出创建了一个新文件 temp/f1 但没有检测到该文件首先被删除。这可能是因为移动文件可以看到如下

• Deleting/Cutting the file f1
• Creating a folder called temp
• Creating/Pasting the file f1

• 删除/剪切文件 f1
• 创建一个名为 temp 的文件夹
• 创建/粘贴文件 f1

Then I came across the setUpdate(true)that looks for updates to files that are already being tracked and will not stage new files. (Check java-doc for more info)

然后我遇到了setUpdate(true)它会查找已被跟踪的文件的更新，并且不会暂存新文件。（查看 java-doc 了解更多信息）

So I had to change my code to two lines like so in order for git to recognize both files added and modified (which includes deletion):

所以我不得不将我的代码更改为两行，以便 git 识别添加和修改的文件（包括删除）：

git.add().addFilepattern(".").call();
git.add().setUpdate(true).addFilepattern(".").call();

git status now gives the expected result:

git status 现在给出了预期的结果：

renamed:    f1.hml -> temp/f1.html

It might be the wildcard, I just read the javadoc for the add command, looks like you send the name of a directory in order to add its contents not a wild card:

它可能是通配符，我刚刚阅读了 add 命令的 javadoc，看起来您发送目录的名称是为了添加其内容而不是通配符：

addFilepattern

public AddCommand addFilepattern(String filepattern)

Parameters: filepattern- File to add content from. Also a leading directory name (e.g. dir to add dir/file1and dir/file2) can be given to add all files in the directory, recursively. Fileglobs (e.g. *.c) are not yet supported.

参数：filepattern- 要从中添加内容的文件。还可以给出前导目录名称（例如要添加的目录dir/file1和dir/file2）以递归地添加目录中的所有文件。尚不支持Fileglobs（例如*.c）。
