Manage Gradle dependencies using Kotlin code in buildSrc
Deprecated
Gradle now includes a mechanism called 'Version Catalogs' that allow dependency coordinates and versions to be shared between subprojects. On top of this Gradle generates a type-safe API to reference the dependencies in your Gradle build scripts. This snippet will no longer be maintained meaning the code samples may become out-of-date. Please check out my latest articles for more up-to-date topics.
Browse all AndroidUsing Kotlin to maintain our Gradle dependencies within the buildSrc directory can be really great.
- Allows us to use a familiar syntax
- Provides auto-complete within Groovy or Kotlin Gradle scripts
- Can click through to a particular dependencies definition
Sweet!
