Recipe to use managed dependency versions

What problem are you trying to solve?

Many builds, including ours, find it convenient to manage dependency versions via a Bill of Materials (BOM).
Amongst our Maven dependency management recipes we have org.openrewrite.maven.ManagedDependencies which provides this functionality for Maven. A Gradle equivalent is desirable.

What precondition(s) should be checked before applying this recipe?

The DependencyHandler.platform() function was added to Gradle in version 5.0. This recipe is inapplicable to earlier versions of Gradle.

Describe the situation before applying the recipe

Assuming the recipe were being configured to manage rewrite versions via rewrite-bom, a build.gradle file might look like this:

dependencies {
    implementation("org.openrewrite:rewrite-core:latest.release")
}

Describe the situation after applying the recipe

dependencies {
    implementation(platform("org.openrewrite:rewrite-bom:latest.release"))
    implementation("org.openrewrite:rewrite-core")
}

Any additional context

After this recipe is created a composite of it and its maven equivalent should be added to rewrite-java-dependencies

Start by reading the existing org.openrewrite.maven.ManagedDependencies recipe and the rewrite-java-dependencies composite. Check how build.gradle dependencies are represented and how DependencyHandler.platform() applies for Gradle 5.0 and later. Done means a Gradle recipe produces the shown BOM platform dependency and removes the managed version from the original dependency.
