* The `default` version is resolved to a specific version via a dependency resolve rule, which looks up the version in a corporate catalog of approved modules.

This rule implementation can be neatly encapsulated in a corporate plugin, and shared across all builds within the organisation.

.Using a custom versioning scheme
====

* You cannot add a dependency with an instance of `Project`. You must turn it into a `ProjectDependency` first.
* You cannot add version catalog bundles directly.
Instead, use the `bundle` method on each configuration.
** Kotlin and Groovy: `implementation(libs.bundles.testing)` becomes `implementation.bundle(libs.bundles.testing)`
