给定现有的YAML，Azure DevOps通过REST API创建生成定义

I know the REST API documentation supports cloning, but does it support creating a build definition that links to a YAML file within the Git repo?

$organization = "my-company"
$project = "MyProject"
$projUrl = "https://dev.azure.com/$($organization)/$($project)/"
$patToken = "<PAT>"
$token = [System.Convert]::ToBase64String([System.Text.Encoding]::ASCII.GetBytes(":$($patToken)"))
$header = @{authorization = "Basic $token"}
$Url = "$($projUrl)_apis/build/definitions?api-version=5.1"

$json = @{
    project = "$($project)";
    name = "My.New.Definition.Linked.To.Existing.YAML.File";
    repository = @{
        url = "<the-https-link-to-my-Git-repo>";
    };
    # The script still fails with definition.Process cannot be null.
    # process = 0;
    path = "\A New Folder";
    type = "build"
}

$body = ($json | ConvertTo-Json -Depth 3)
Invoke-RestMethod -Uri $Url -Headers $header -Body $body -Method Post -ContentType application/json;

上面的脚本出现以下错误:

I get the following error with the script above:

Invoke-RestMethod : {"$id":"1","innerException":null,"message":"Value cannot be null.\r\nParameter name:
definition.Process","typeName":"System.ArgumentNullException, mscorlib","typeKey":"ArgumentNullException","errorCode":0,"eventId":0}

是否可以创建新的构建定义而无需克隆必须通过Web UI手动创建的现有构建定义?

Is it possible to create a new build definition without cloning an existing one I have to manually create via the web UI?

我在Git存储库内的/azure-pipeline-YAML/文件夹中有100多个YAML文件.我怀疑我需要以某种方式将其包含在通过REST API发送的JSON中，但是在哪里/如何进行?我陷入了这个 definition.Process 错误.

I have the 100+ YAML files located in a folder /azure-pipeline-YAML/ inside the Git repo. I suspect I need to somehow include that in the JSON I send via the REST API, but where/how? I'm stuck at this definition.Process error.

由于@danielmann，我最终需要获取一些其他信息(即 repository.Id 并更改 repository.Type ).我在脚本中添加了以下内容，以获取基于现有YAML文件创建的临时定义的示例.

Thanks to @danielmann I ended up needing to get some additional info (i.e. repository.Id and changing the repository.Type). I put the following in the script to get an example of a temporary definition I created based on an existing YAML file.

$Url = "$($projUrl)_apis/build/definitions/13?api-version=5.1"
Invoke-RestMethod $Url -Headers $header -Method Get -ContentType application/json;

工作脚本最终变为:

$organization = "my-company"
$project = "MyProject"
$projUrl = "https://dev.azure.com/$($organization)/$($project)/"
$patToken = "<PAT>"
$token = [System.Convert]::ToBase64String([System.Text.Encoding]::ASCII.GetBytes(":$($patToken)"))
$header = @{authorization = "Basic $token"}
$Url = "$($projUrl)_apis/build/definitions?api-version=5.1"

$json = @{
    project = "$($project)";
    name = "My.New.Definition.Linked.To.Existing.YAML.File";
    repository = @{
        url = "<the-https-link-to-my-Git-repo>";
        defaultBranch = "refs/heads/feature/my-new-feature-branch";
        id = "<taken-from-the-GET-API-request>";
        type = "TfsGit";
    };
    process = @{
        yamlFilename = "azure-pipeline-YAML/my-pipeline.yml";
        type = 2;
    };
    path = "\A New Folder";
    type = "build";
}

$body = ($json | ConvertTo-Json -Depth 3)
Invoke-RestMethod -Uri $Url -Headers $header -Body $body -Method Post -ContentType application/json;
