Adding a Configuration as a dependency is a confusing behavior which isn't recommended

Question

I have encountered the following warning after trying to build my Kotlin project with Gradle 7.

> Configure project :app
Adding a Configuration as a dependency is a confusing behavior which isn't recommended. This behaviour has been deprecated and is scheduled to be removed in Gradle 8.0. If you're interested in inheriting the dependencies from the Configuration you are adding, you should use Configuration#extendsFrom instead. See https://docs.gradle.org/6.7/dsl/org.gradle.api.artifacts.Configuration.html#org.gradle.api.artifacts.Configuration:extendsFrom(org.gradle.api.artifacts.Configuration[]) for more details.

This is what I have found in the Gradle source files.

        when:

        then:
        succeeds "dependencies", '--configuration', 'conf'
    }

What have I done wrong?

Answer 1

Change your Kotlin version to 1.4.30 or higher

ext.kotlin_version = '1.4.30'

Then you can run ./gradlew build --warning-mode=all --stacktrace to verify the fix.

As pointed out in the comments, the Kotlin Gradle Plugin had a bug and this is now fixed.

Answer 2

Gradle dependencies are organized using configurations, for example implementation, api, testImplementation and so on. Most Gradle projects just use configurations that are defined by common plugins, e.g. the Java plugin, but it is possible to create custom configurations:

configurations {
    myCustomConfiguration
}

dependencies {
    // my first dependency is a regular dependency
    implementation 'org.foo:foo:1.0'
    // my second dependency is for a custom use case (e.g. some special application classpath)
    myCustomConfiguration 'org.bar:bar:1.0'
}

Configurations might get resolved, which means the dependencies will be downloaded if necessary and then they will be available as files for whatever comes next (e.g. for compilation of production or test code). Since configurations often need to contain the same dependencies (e.g. test code also needs to access production dependencies), it is possible to let configurations inherit from each other:

configurations {
    // myCustomConfiguration should automatically contain all dependencies added to implementation
    myCustomConfiguration.extendsFrom(implementation)
}

Using Gradle, it was possible to use another syntax for this functionality:

dependencies {
    // add all dependencies of implementation to myCustomConfiguration
    myCustomConfiguration configurations.implementation
}

The two code blocks above do the same, but the second one should not be used (and won't work starting with Gradle 8.0), because it somehow mixes the concepts of configurations and dependencies.

If you receive this warning, you probably have a line similar to the one in the last code block. However, it might be possible, that the deprecated code is part of a 3rd party plugin you are using in your project. For now, it will still work, but it won't once you upgrade to Gradle 8.0 or above.
