Git tag at the end of build on Visual Studio Online (Build vNext, hosted pool)

Question

I\'d like to automatically tag a commit when a build is successful on VSO build vNext. I\'ve read the doc including this page https://msdn.microsoft.com/Library/vs/alm/Build/scr

I'm answering myself on what I was trying to do (git tag was one of the few tasks I wanted to do). It's now possible to execute git commands in scripts. The documentation is here : https://www.visualstudio.com/en-us/docs/build/scripts/git-commands

Here is the howto:

Enable scripts to run Git commands

Grant version control permissions to the build service:

• Go to the Version Control control panel tab ▼
• On the Version Control tab, select the repository in which you want to run Git commands, and then select Project Collection Build Service.
• Grant permissions needed for the Git commands you want to run.

Typically you'll want to grant:

• Branch creation: Allow
• Contribute: Allow
• Read: Inherited allow
• Tag creation: Inherited allow

When you're done granting the permissions, make sure to click Save changes.

Enable your build definition to run Git.exe

On the variables tab set this variable: system.prefergit to true

On the options tab select Allow scripts to access OAuth token.
