Gradle Extra Properties

Internal

• Gradle Runtime and Project Configuration

Overview

Extra properties allow defining variables that are used multiple times within the same script, such as a file that is referred from multiple locations of the build script. An extra property is a user-defined variable. Internally, these properties are stored as key-value pairs in a map, associated with the project.

To add properties, use the "ext" namespace:

ext {
    color = 'blue'
}

project.color = 'red'

task displayColor {
    doLast {
        println color
    }
}

For the above example, './gradlew displayColor' will display "red".
