如何在我的PS脚本中获取Git commit哈希? [英] How can I get the Git commit hash in my PS script?

问题描述

我正在使用PowerShell脚本调用msbuild，并将版本号传递给OctopusDeploy，如下所示:

I'm using a PowerShell script to call msbuild and pass in a version number to OctopusDeploy like this:

msbuild "Xyz.sln" /t:Rebuild /p:Configuration=Release /p:RunOctoPack=true /p:OctopackPackageVersion=$versionNumber

...其中$ versionNumber在PS脚本中生成.我想做的是将Git commit哈希的前16个字符添加到版本字符串的末尾，这样它最终看起来像:

... where $versionNumber is generated in the PS script. What I want to do is add the first 16 characters of the Git commit hash to the end of the version string so it will end up looking like:

2.yyyyMMdd.HHmmss-git-6d34e44340f95c2a

我该怎么做?考虑到它们已经内置了Git支持，我是否可以让msbuild或Visual Studio以某种方式返回当前的git commit哈希?

How can I do this? Can I get msbuild or Visual Studio to return the current git commit hash somehow, considering they now have built-in Git support?

推荐答案

我最后所做的只是将Powershell脚本(文件NGit.dll，Sharpen.dll和ICSharpCode.SharpZipLib.dll)旁边的束NGit捆绑在一起，然后使用这样的代码生成带有git hash后缀的版本号:

What I did in the end was just bundle NGit next to my Powershell script (files NGit.dll, Sharpen.dll, and ICSharpCode.SharpZipLib.dll) then use some code like this to generate the version number with git hash suffixed:

[System.Reflection.Assembly]::LoadFrom("Ngit.dll") | Out-Null
[System.Reflection.Assembly]::LoadFrom("Sharpen.dll") | Out-Null
[System.Reflection.Assembly]::LoadFrom("ICSharpCode.SharpZipLib.dll") | Out-Null

# *** Git repo base path (should contain .sln file) ***
$repoPath = "C:\Path\To\Repo"

# *** OctopusDeploy API key for publishing ***
$octoApiKey = "API-[PublishKey]"

#######################################################

# *** Get and process current Git commit hash ***
$sharpenRepoPath = New-Object -TypeName Sharpen.FilePath -ArgumentList "$($repoPath)\.git"
$repoBuilder = New-Object -TypeName NGit.RepositoryBuilder
$repo = $repoBuilder.SetGitDir($sharpenRepoPath).Build()
$headHash = $repo.Resolve("HEAD").Name.Substring(0,12)

# *** Version when pushing to OctopusDeploy NuGet ***
$versionNumber = "2." + [datetime]::now.tostring("yyyyMMdd.HHmmss") + "-git-" + $headHash

# *** Pause before publish ****
Write-Host "About to publish to OctopusDeploy NuGet with version number:"
Write-Host "    $($versionNumber)"
cmd /c pause

# *** OctopusDeploy build and push ***
msbuild "$repoPath\MySolution.sln" /t:Rebuild /p:Configuration=Release /p:RunOctoPack=true /p:OctopackPackageVersion=$versionNumber /p:OctoPackPublishPackageToHttp=https://my.nuget.server/nuget/packages /p:OctoPackPublishApiKey=$octoApiKey
