Documentation says:
Build.BuildId - The ID of the record for the completed build.
Build.BuildNumber - The name of the completed build, also known as the run number and that it can be customized.
If you create a fresh build pipeline and do not customize BuildNumber format:
it will be given a unique integer as its name
In this case, is BuildNumber and BuildId exactly the same?
No, it's not necessary the same. I just checked my classic and yml pipelines.
For classic build id and number are integers and are the same if not customized.
For yml build pipeline and build id is an integer and build number consists of current date and number of tries per day. As per documentation the format is $(Date:yyyyMMdd).$(Rev:r).
In this case, is BuildNumber and BuildId exactly the same?
Yes. When you don't customize BuildNumber format, the value of the two variables are the same.
Here is an example：
No define Build number:
output the two variables:
- powershell: |
echo $(build.buildid)
echo $(build.buildnumber)
displayName: 'PowerShell Script'
Result: The value is same.
