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

Solution 3:

I was facing the same issue,

"Errors running builder 'Integrated External Tool Builder' on project {PROJECT NAME}"

you must go to your .project file in your work space, and you can put in comment or delete this lines

<buildCommand>
            <name>org.eclipse.ui.externaltools.ExternalToolBuilder</name>
            <triggers>full,incremental,</triggers>
            ...
            ...

</buildCommand>

and after that, you can rebuild your project and it will work correctly.

Solution 4:

In my case, this happened after fiddling with existing builders (e.g. renaming them) and the solution was to restart Eclipse (Neon.3 v4.6.3).
