Compile-safe access to parameters supplied to a Gradle build. Compatible with Java 8 and Gradle 7.1 or later.

Primer

Describe build parameters using a rich DSL:

plugins {
    id("org.gradlex.build-parameters")
}

buildParameters {
    group("deployment") {
        string("username") {
            description.set("The username used for deploying to the artifact repository")
            defaultValue.set("deployer")
        }
        string("password") {
            description.set("The password used for deploying to the artifact repository")
        }
    }
}

Use compile-safe accessor in you build scripts to access parameter values:

plugins {
    id("build-parameters")
}

publishing {
    repositories {
        maven {
            url = uri("https://repo.my-company.com")
            credentials {
                // username has a default and is therefore of type String
                username = buildParameters.deployment.username
                // password does not have a default and is therefore of type Provider<String>
                password = buildParameters.deployment.password.get()
            }
        }
    }
}

Run your build and pass the parameters to it using -P commandline parameters:

./gradlew :publish -Pdeployment.username="jane" -Pdeployment.password="super-secret"

Or explore available parameters by running the parameters task:

Usage

See the plugin's documentation page for more details on how to configure your build.
