How do I automatically clear VS Code terminal when starting a build?

Question

I press Ctrl+Shift+B to start a build in Visual Studio Code (it's configured to just run GNU Make), and the build tool output is written to the Terminal window.

However, it's appended to the output from the previous build, which is confusing.

How do I configure VS Code to clear the terminal window before starting a new build?

November 2018 Update

As of this commit (and a few subsequent follow-ups), you can now add a clear presentation option to your task to have it clear the terminal before each task run.

Working example (on fresh clone+build):

{     // See https://go.microsoft.com/fwlink/?LinkId=733558     // for the documentation about the tasks.json format     "version": "2.0.0",     "tasks": [         {             "label": "[gcc] Build",             "type": "shell",             "command": "g++",             "args": [                 "source.h",                 "-Wall",                 "-o",                 "a.out"             ],             "presentation": {                 "clear": true                        // <-- this line             }         }     ] } 

(Note: the linked commit diff has the key being named clearBeforeExecuting but it's apparently since been changed to just clear).

Prior to this, I created a clear_g++ script on my path with just:

#!/bin/bash clear exec g++ $* 

And changed my command from g++ to clear_g++.

Since I liked the idea of this approach but it didn't end up working out.
