[java] How to run Gradle from the command line on Mac bash

I have a very simple question. I am brand new to Mac and I am trying to get my Java project moved over to my new Mac. The project has a Gradlew file that I thought I could run from the command line to build and run on any machine. When I do gradlew from the command line (in the location of the gradlew file) it says gradlew not found. Am I missing something on how to run a command from a bash shell?

Also, if you don't have the gradlew file in your current directory:

You can install gradle with homebrew with the following command:

$ brew install gradle

As mentioned in this answer. Then, you are not going to need to include it in your path (homebrew will take care of that) and you can just run (from any directory):

$ gradle test
