Tested on TS5 and was able to produce a Build Failure:

@vinceclifford No programming exercises are currently working on TS5. It seems like Docker isn't setup correctly.

From Jenkins' logs:

groovy.lang.MissingPropertyException: No such property: docker for class: groovy.lang.Binding

@magaupp @vinceclifford The Jenkins setup should be fixed now.

The merge-base changed after approval.
