在使用JGit进行拉取后获取已更改文件的列表 [英] Get the list of changed files after a pull with JGit

问题描述

我使用它来获得所有合并的提交，但是，我想知道如何在提取请求后检索已更改文件的列表。我想知道所有更改的文件。

  Git git = new Git（localRepo）; 
 PullCommand pullCmd = git.pull（）; 
 PullResult pullResult = pullCmd.call（）; 
 MergeResult mergeResult = pullResult.getMergeResult（）; 
 ObjectId [] mergedCommits = mergeResult.getMergedCommits（）; 
 
（ObjectId mergedCommit：mergedCommits）{
 //现在呢？ 
} 
  

解决方案

问题：

获取当前头之前：

  ObjectId oldHead = repository.resolve（HEAD ^ {tree}）; 
  

之后再次拉：

  ObjectId head = repository.resolve（HEAD ^ {tree}）; 
  

然后您应该能够像我该怎么做相当于git diff - 名称状态"与jgit？：

  ObjectReader reader = repository.newObjectReader（）; 
 CanonicalTreeParser oldTreeIter = new CanonicalTreeParser（）; 
 oldTreeIter.reset（reader，oldHead）; 
 CanonicalTreeParser newTreeIter = new CanonicalTreeParser（）; 
 newTreeIter.reset（reader，head）; 
列表< DiffEntry> diffs = git.diff（）
 .setNewTree（newTreeIter）
 .setOldTree（oldTreeIter）
 .call（）; 
  

I would like to know how I can retrieve the list of changed files after a pull request.

I'm using this to get all the merged commits, but I want to know all the changed files.

Git git = new Git(localRepo);
PullCommand pullCmd = git.pull();
PullResult pullResult = pullCmd.call();
MergeResult mergeResult = pullResult.getMergeResult();
ObjectId[] mergedCommits = mergeResult.getMergedCommits();

for (ObjectId mergedCommit : mergedCommits) {
  // And now?
}

解决方案

Building on the previous comments/questions:

Get the current head before you pull:

ObjectId oldHead = repository.resolve("HEAD^{tree}");

And after the pull again:

ObjectId head = repository.resolve("HEAD^{tree}");

Then you should be able to run the diff the same way as in How do I do the equivalent of "git diff --name-status" with jgit?:

ObjectReader reader = repository.newObjectReader();
CanonicalTreeParser oldTreeIter = new CanonicalTreeParser();
oldTreeIter.reset(reader, oldHead);
CanonicalTreeParser newTreeIter = new CanonicalTreeParser();
newTreeIter.reset(reader, head);
List<DiffEntry> diffs= git.diff()
                    .setNewTree(newTreeIter)
                    .setOldTree(oldTreeIter)
                    .call();
