zsh "command not found: plugin:" for build.gradle - intellij-idea

Question

I've used Maven a few times before, but I'm new to Gradle. I'm using Intellij IDEA 14.0.2 on Mac OS X 10.10.1. I also have ruby with rails installed. "gem update" shows that I have the latest.
I also have brew & oh_my_zsh installed and the latest.
Ok back to my problem. My purpose is to change a small project from Maven to Gradle. I created a new module for Gradle with IDEA:
apply plugin: 'java'
sourceCompatibility = 1.5
version = '1.0'
repositories {
mavenCentral()
}
dependencies {
testCompile group: 'junit', name: 'junit', version: '4.11'
}
The output when running is:
/bin/bash /Users/lucianirimie/BCD/bcd-remote-tests/Gradle/build.gradle
zsh:1: command not found: plugin:
/Users/lucianirimie/BCD/bcd-remote-tests/Gradle/build.gradle: line 3: sourceCompatibility: command not found
/Users/lucianirimie/BCD/bcd-remote-tests/Gradle/build.gradle: line 4: version: command not found
/Users/lucianirimie/BCD/bcd-remote-tests/Gradle/build.gradle: line 6: repositories: command not found

Executing a Gradle build requires the installation of Gradle, or the use of a the Gradle wrapper. Take a look at the Gradle docs for installation instructions. I do believe Gradle is available via Brew as well. With the gradle command properly registered on your path, you would build your project something like this (from the folder with the build.gradle file.
$ gradle build
