java – 使用JGit从Git检索提交消息日志

我只想从Git存储库中检索commitlog,该存储库包含您在特定repopsitory上完成的所有提交的消息.我找到了一些用于实现此目的的代码片段,并以异常结束.

try {
    FileRepositoryBuilder builder = new FileRepositoryBuilder();
    Repository repo = builder.setGitDir(new File("https://github.com/name/repository.git")).readEnvironment().findGitDir().build();
    RevWalk walk =new RevWalk(repo);
    ObjectId head = repo.resolve(Constants.HEAD);
    RevCommit commit =walk.parseCommit(head);
    Git git =new Git(repo);
    Iterable<RevCommit> gitLog = git.log().call();
    Iterator<RevCommit> it = gitLog.iterator();
    while(it.hasNext())
    {
        RevCommit logMessage = it.next(); 
        System.out.println(logMessage.getFullMessage());
    }
}
catch(Exception e) {
    e.printStackTrace();
}

但它给了我：

org.eclipse.jgit.api.errors.NoHeadException: No HEAD exists and no explicit starting revision was specified exception.

我怎么摆脱这个？我正在使用org.eclipse.jgit JAR版本2.0.0.201206130900-r

解决方法:

这是正确的一段代码将做上述..

FileRepositoryBuilder builder = new FileRepositoryBuilder();
Repository repo = builder.setGitDir(new File("localrepositary"+"\\.git")).setMustExist(true).build();
Git git = new Git(repo);
Iterable<RevCommit> log = git.log().call();
for (Iterator<RevCommit> iterator = log.iterator(); iterator.hasNext();) {
  RevCommit rev = iterator.next();
  logMessages.add(rev.getFullMessage());
}
