Can you provide a more detailed instruction on how to run gradle?
Got the answer but can't submit. A more detailed instruction will go a long way. Very frustrating :(
If you are using IntelliJ (which is the IDE Treehouse recommends) then you should have a "Gradle" tab that you can click on over on the right sidebar of the IDE window. If you can't see that button then you can open the window by clicking on the "View" menu on the top toolbar then "Tool Windows" then "Gradle".
Once the Gradle window opens up you just need to expand the "Tasks" and "treehouse" options and then double click on the "prepareSubmission" task.
