JGit如何检查分支是否合并到master

代码迁移过程– GitHub-概述

  1. 开发人员创建分支,编写代码等。
  2. 开发人员在工作完成后提交分支
  3. 生产迁移–开发人员执行拉取请求,将分支拉入master。
  4. 完成两次批准后,开发人员可以合并代码
  5. 开发人员将代码合并到母版中
  6. 在生产环境中运行Git以从中克隆存储库 master ... 我正在使用JGit编写自定义程序以验证合并是否已完成到master。
  7. 代码已部署到生产环境

问题:

我正在尝试从语法上检查开发人员是否已将其代码合并到主代码中。我无法执行此步骤。我审阅过的所有示例均已提交给分支机构和master。此后,示例随后检查分支是否已提交。这对我的程序而言不是可行的选择,因为合并是在批准完成后在GitHub中进行的。

当我克隆存储库JGit并尝试检查其他分支是否已合并时,解析提交失败并返回null。反之亦然,如果我克隆了分支并检查master是否有提交,它也会失败。很明显,我在这里做错了。我正在谈论的示例代码:

try( RevWalk revWalk = new RevWalk( repository ) ) {
  RevCommit masterHead = revWalk.parseCommit( repository.resolve( "refs/heads/master" );
  RevCommit otherHead = revWalk.parseCommit( repository.resolve( "refs/heads/other-branch" );
  if( revWalk.isMergedInto( otherHead, masterHead ) ) {
   ...
  }
}

我还尝试查看存储库状态,但这也不起作用。如果除了使用git命令行工具之外还有其他想法,我将不胜感激。

How to merge in JGit?

How to determine with JGit which branches have been merged to master?

我的代码

public class GitHubTest
{
  public Repository repository;

  public GitHubTest()
  {
  }

  public static ArrayList<String> fetchGitBranches(String gitUrl)
  {
     Collection<Ref> refs;

     try {
        refs = Git.lsRemoteRepository().setHeads(true)
        .setRemote(gitUrl)
        .setCredentialsProvider(new UsernamePasswordCredentialsProvider("token", "not applicable stack exchange"))
        .call();
        for (Ref ref: refs) {
           branches.add(ref.getName().substring(ref.getName().lastIndexOf("/") + 1, ref.getName().length()));
           System.out.println(ref.getName());
        }
        Collections.sort(branches);
     } catch (InvalidRemoteException e) {

        System.out.println("r.canCommit();  =" + r.canCommit());
        //System.out.println("r.canCommit();  ="+r. );

        if (r == RepositoryState.MERGING) {

        // Get the object the reference points to
        ObjectId masterTip = master.getObjectId();
     } catch (Exception e) {

     ArrayList<String> al = gitHubTest.fetchGitBranches("https://github.com/FICOCorp/iww-test-create-1552931848516.git");

     for (String s: al) {
        System.out.println("Known Branches " + s);

     }

JGit无法做到这一点。解决方案是在GitHub中调用rest API,特别是“拉”请求服务。
