Android Studio: How do I find where Gradle has been installed?

Question

I have installed Android Studio but would like to use Gradle to build a simple "hello world" Java application that I have created outside of AS.

I have added the java plugin to my build.gradle file and ran `"gradle build" to try and build the .java file.

However, I am getting the error: "Gradle is not recognised as an internal or external command"

Do I need to install a separate version of Gradle, not bundled with AS to be able to build a java project?

More or less.

There are two ways of using Gradle:

• Download and install it, like you would most other development tools

• Have a project set up for the Gradle Wrapper ( gradlew and gradlew.bat files in the project root, plus the gradle/ directory containing the Wrapper JAR and properties file)

That latter approach will download a private copy of Gradle for this particular project, into the project's .gradle/ directory. This way, different projects can use different versions of Gradle without conflict.

Android Studio takes the latter approach; you can see the files that I mentioned in a newly-created Android Studio project, for example. For your own Java project, I'd do whatever is natural for your IDE that you plan on using for that project.
