New features and usability improvements

Publishing improvements

New PublishingExtension.getSoftwareComponentFactory() method

This release introduces a new method that exposes the SoftwareComponentFactory service via the publishing extension, simplifying the creation of publishable components. In many cases, a component is already present. For example, the bundled Java plugins already provide the java component by default. This new method is especially useful for plugin authors who want to create and publish custom components without needing to depend on the Java plugins.

The following example shows how to use this new method to publish a custom component:

plugins {
    id("maven-publish")
}

val consumableConfiguration: Configuration = getAConfiguration()

publishing {
    val myCustomComponent = softwareComponentFactory.adhoc("myCustomComponent")
    myCustomComponent.addVariantsFromConfiguration(consumableConfiguration) {}
    
    publications {
        create<MavenPublication>("maven") {
            from(myCustomComponent)
        }
    }
}

New provider-based methods for publishing configurations

Two new methods have been added to AdhocComponentWithVariants which accept providers of consumable configurations:

• void addVariantsFromConfiguration(Provider<ConsumableConfiguration>, Action<? super ConfigurationVariantDetails>)
• void withVariantsFromConfiguration(Provider<ConsumableConfiguration>, Action<? super ConfigurationVariantDetails>)

These complement the existing methods that accept realized configuration instances.

With this new API, configurations can remain lazy and are only realized when actually needed for publishing. Consider the following example:

plugins {
    id("base")
    id("maven-publish")
}

group = "org.example"
version = "1.0"

val myTask = tasks.register<Jar>("myTask")
val variantDependencies = configurations.dependencyScope("variantDependencies")
val myNewVariant: NamedDomainObjectProvider<ConsumableConfiguration> = configurations.consumable("myNewVariant") {
    extendsFrom(variantDependencies.get())
    outgoing {
        artifact(myTask)
    }
    attributes {
        attribute(Category.CATEGORY_ATTRIBUTE, objects.named<Category>("foo"))
    }
}

publishing {
    val component = softwareComponentFactory.adhoc("component")
    // This new overload now accepts a lazy provider of consumable configuration
    component.addVariantsFromConfiguration(myNewVariant) {}

    repositories {
        maven {
            url = uri("<your repo url>")
        }
    }
    publications {
        create<MavenPublication>("myPublication") {
            from(component)
        }
    }
}

With this approach, the myNewVariant configuration will only be realized if the myPublication publication is actually published.

Promoted features

Promoted features are features that were incubating in previous versions of Gradle but are now supported and subject to backward compatibility. See the User Manual section on the "Feature Lifecycle" for more information.

The following are the features that have been promoted in this Gradle release.

Daemon toolchain is now stable

Gradle introduced the Daemon toolchain in Gradle 8.8 as an incubating feature. Since then the feature has been improved and stabilized. It is now considered stable and will no longer print an incubation warning when used.
