Throw instead of failing build on exception

[ThrownToys]

This PR adds an optional boolean shouldFailBuild, defaulted to true, which when disabled will throw an error instead of failing the build.

This addresses issue #567

Testing done

Unit test has been added (I'm actually not sure how to run this locally, so I'm hoping build checks will run this for me).
