本文整理了Java中org.eclipse.jgit.lib.Repository.resolve方法的一些代码示例，展示了Repository.resolve的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Repository.resolve方法的具体详情如下：
包路径：org.eclipse.jgit.lib.Repository
类名称：Repository
方法名：resolve

Repository.resolve介绍

[英]Parse a git revision string and return an object id. Combinations of these operators are supported:

  • HEAD, MERGE_HEAD, FETCH_HEAD
  • SHA-1: a complete or abbreviated SHA-1
  • refs/...: a complete reference name
  • short-name: a short reference name under refs/heads, refs/tags, or refs/remotes namespace
  • tag-NN-gABBREV: output from describe, parsed by treating ABBREV as an abbreviated SHA-1.
  • id^: first parent of commit id, this is the same as id^1
  • id^0: ensure id is a commit
  • id^n: n-th parent of commit id
  • id~n: n-th historical ancestor of id, by first parent. id~3 is equivalent to id^1^1^1 or id^^^.
  • id:path: Lookup path under tree named by id
  • id^{commit}: ensure id is a commit
  • id^{tree}: ensure id is a tree
  • id^{tag}: ensure id is a tag
  • id^{blob}: ensure id is a blob

The following operators are specified by Git conventions, but are not supported by this method:

  • ref@{n}: n-th version of ref as given by its reflog
  • ref@{time}: value of ref at the designated time
    [中]解析git修订字符串并返回对象id。支持以下运算符的组合：
    *头，合并头，取头
    *SHA-1：完整或缩写的SHA-1
    *参考文献/…：完整的引用名
    *短名称：refs/heads、refs/tags或refs/remotes命名空间下的短引用名称
    *tag NN gABBREV:descripe的输出，通过将ABBREV作为缩写SHA-1进行解析。
    *id^：提交id的第一个父级，与id ^1相同
    *id ^0:确保id为提交
    *id^n:提交id的第n个父级
    *id~n:id的第n个历史祖先，由第一个父代继承。id~3相当于id^1^1^1或id^^。
    *id:path:查找由id命名的树下的路径
    *id^{commit}：确保id是commit
    *id^{tree}：确保id是树
    *id^{tag}：确保id是一个标记
    *id^{blob}：确保id是blob
    以下运算符由Git约定指定，但此方法不支持：
    *ref@{n}：ref的第n个版本，由reflog给出
    *ref@{time}：指定时间的ref值
