Eclipse - Errors running builder on project

Issue

I was getting this error constantly in eclipse:

Errors during build. Errors running builder "Integrated External Tool Builder" on project project. The builder launch configuration could not be found. Errors running builder "Integrated External Tool Builder" on project project. The builder launch configuration could not be found.

Solution

I added this question and answering on my own as I could not find an answer on Stackoverflow and it may benefit someone else

Answer is:

On your project "project", right click -> Properties>Builders Remove the missing builder
