这是我在基于其他解决方案的makefile中所做的。注意，这不仅为代码提供了一个修订号，还附加了允许您重新创建版本的散列。

# Set the source control revision similar to subversion to use in 'c'
# files as a define.
# You must build in the master branch otherwise the build branch will
# be prepended to the revision and/or "dirty" appended. This is to
# clearly ID developer builds.
REPO_REVISION_:=$(shell git rev-list HEAD --count)
BUILD_BRANCH:=$(shell git rev-parse --abbrev-ref HEAD)
BUILD_REV_ID:=$(shell git rev-parse HEAD)
BUILD_REV_ID_SHORT:=$(shell git describe --long --tags --dirty --always)
ifeq ($(BUILD_BRANCH), master)
REPO_REVISION:=$(REPO_REVISION_)_g$(BUILD_REV_ID_SHORT)
else
REPO_REVISION:=$(BUILD_BRANCH)_$(REPO_REVISION_)_r$(BUILD_REV_ID_SHORT)
endif
export REPO_REVISION
export BUILD_BRANCH
export BUILD_REV_ID

我编写了一些PowerShell实用程序，用于从Git中检索版本信息并简化标记

函数:Get-LastVersion, Get-Revision, Get-NextMajorVersion, Get-NextMinorVersion, TagNextMajorVersion, TagNextMinorVersion:

# Returns the last version by analysing existing tags,
# assumes an initial tag is present, and
# assumes tags are named v{major}.{minor}.[{revision}]
#
function Get-LastVersion(){
  $lastTagCommit = git rev-list --tags --max-count=1
  $lastTag = git describe --tags $lastTagCommit
  $tagPrefix = "v"
  $versionString = $lastTag -replace "$tagPrefix", ""
  Write-Host -NoNewline "last tagged commit "
  Write-Host -NoNewline -ForegroundColor "yellow" $lastTag
  Write-Host -NoNewline " revision "
  Write-Host -ForegroundColor "yellow" "$lastTagCommit"
  [reflection.assembly]::LoadWithPartialName("System.Version")

  $version = New-Object System.Version($versionString)
  return $version;
}

# Returns current revision by counting the number of commits to HEAD
function Get-Revision(){
   $lastTagCommit = git rev-list HEAD
   $revs  = git rev-list $lastTagCommit |  Measure-Object -Line
   return $revs.Lines
}

# Returns the next major version {major}.{minor}.{revision}
function Get-NextMajorVersion(){
    $version = Get-LastVersion;
    [reflection.assembly]::LoadWithPartialName("System.Version")
    [int] $major = $version.Major+1;
    $rev = Get-Revision
    $nextMajor = New-Object System.Version($major, 0, $rev);
    return $nextMajor;
}

# Returns the next minor version {major}.{minor}.{revision}
function Get-NextMinorVersion(){
    $version = Get-LastVersion;
    [reflection.assembly]::LoadWithPartialName("System.Version")
    [int] $minor = $version.Minor+1;
    $rev = Get-Revision
    $next = New-Object System.Version($version.Major, $minor, $rev);
    return $next;
}

# Creates a tag with the next minor version
function TagNextMinorVersion($tagMessage){
    $version = Get-NextMinorVersion;
    $tagName = "v{0}" -f "$version".Trim();
    Write-Host -NoNewline "Tagging next minor version to ";
    Write-Host -ForegroundColor DarkYellow "$tagName";
    git tag -a $tagName -m $tagMessage
}

# Creates a tag with the next major version (minor version starts again at 0)
function TagNextMajorVersion($tagMessage){
    $version = Get-NextMajorVersion;
    $tagName = "v{0}" -f "$version".Trim();
    Write-Host -NoNewline "Tagging next majo version to ";
    Write-Host -ForegroundColor DarkYellow "$tagName";
    git tag -a $tagName -m $tagMessage
}

除了提交的SHA-1 id，服务器时间的日期和时间也有帮助吗?

就像这样:

Commit happened at 11:30:25 on 2013年8月19日将显示为 6886年bbb7be18e63fc4be68ba41917b48f02e09d7_19aug2013_113025

每个提交都有一个唯一的散列。除此之外，git中没有修订号。如果您想要更加用户友好，就必须自己标记提交。

提交的SHA1哈希值相当于Subversion修订号。

不管对你来说是好消息还是坏消息，哈希值就是修订号。当我从SVN切换到git时，我也遇到了这个问题。

你可以在git中使用“tagging”将某个修订标记为特定版本的“release”，这样就可以方便地引用该修订。看看这篇博客文章。

要理解的关键是git不能有修订号——想想去中心化的本质。如果用户A和B都提交到他们的本地存储库，git如何合理地分配一个连续的修订号?在他们相互推动/拉动对方的变化之前，A对B一无所知。

另一件需要考虑的事情是用于修复错误的分支的简化分支:

从一个版本开始:3.0.8。然后，在释放之后，这样做:

git branch bugfixes308

这将为错误修复创建一个分支。检查分支:

git checkout bugfixes308

现在进行任何您想要的错误修复更改。

git commit -a

提交它们，然后切换回主分支:

git checkout master

然后从另一个分支中导入这些更改:

git merge bugfixes308

这样，您就有了一个单独的特定于发行版的错误修复分支，但是您仍然将错误修复更改拉到您的主开发主干中。
