One of the recommended approaches to resolve this issue is to have a different name, but you can also switch cases when defining sub groups, like retrofitRx or retrofitMoshi. Simply put, a gradle takes all the source files (java and XML) and applies appropriate tools, e.g., converts the java files into dex files and compresses all of them into a single file known as apk that is actually used. Try to run the project and debug any errors using the Troubleshooting Guide. Every Android project needs a Gradle for generating an apk from the. Run gradle wrapper -gradle-version 7.0 to update the project to 7.0. The reason for it is, we are defining other aliases like retrofit-rx or retrofit-moshi, so Gradle has to generate sub group accessors for them as well. The previous step will help you identify potential problems by issuing deprecation warnings when a plugin does try to use a deprecated part of the API. For example, if you look at our retrofit declarations we used the alias retrofit-base instead of just retrofit. Later I learn that it’s illegal to have an alias to dependency which also belongs to a nested group. So use it at your own risk.Īlias naming: When I was first started exploring this feature and started creating aliases, I quickly ran into build errors when defining alias names. Preview Feature: Let’s get this out of the way first, this still a preview feature, so it’s subjected to change and may also be unreliable in certain cases. Now let’s take a step back and see what are some of the gotchas when using this feature. So far we have talked about how amazing and useful the version catalog is. But feel free to use whatever approach you find comfortable with. Personally, I like this approach, this kind of configuration file allows us to share across org if required, gives a quick overview of all the dependencies (excluding transitive dependencies) in the project. That’s it, we have our configuration file and we can start referencing the generated type-safe accessors in our build scripts. Here is a small example of how the generated type-safe accessor will look like. I will be using Gradle Kotlin DSL for examples, but this can be used with Groovy as well This feature allows us to define our dependencies and versions in a separate configuration file (or in the file) and then Gradle will generate type-safe accessors that can be used in the build scripts with auto-completion in IDE.Ī version catalog is a list of dependencies, represented as dependency coordinates, that a user can pick from when declaring dependencies in a build script. Version catalog is a preview feature that is available in Gradle 7.0.0. You can refer this article for more information on these approaches: Kotlin + buildSrc for Better Gradle Dependency Management – Handstand Sam Gradle Version Catalog One downside of this approach is, if you’re just changing versions in the config file, Gradle will rebuild the entire buildSrc which includes plugins you defined. In this approach you get the benefit of sharing your dependencies as well as using Kotlin for Gradle build files, this approach provides you with auto-completion of the versions/dependencies in your Gradle files. compileSdkVersion This is used to define the API level of the app and the app can use the features of this and lower level. Gradle buildSrc & Kotlin DSL: This approach became quite popular with a lot of developers recently and even the Android team uses this approach in the Jetpack libraries. The Module-level adle supports various build configurations like: android: This block is used for configuring the specific android build options. It’s a step up from manual dependency management. With this approach, you can share the dependencies or versions or both. Gradle extra property: This approach is quite popular with a lot of developers and you can find it being used in a lot of open-source projects and Google recommends this approach as well in their docs. It gets annoying to manage dependencies either for version updates or adding/removing as the projects grow and adds more modules. Manual management: This is the basic approach that we get when we create a project, while this is good enough for most single module projects. The version used is the one defined in the adle file.There are few different approaches for managing dependencies, these are generally used approaches (at least on the Android development side). I'm using v1.5.1 and in the settings I've selected the "Use default gradle wrapper" option, which means that instead of using a local gradle install for every project, a specific gradle version will be used for each project. I'd like to upgrade to that version in Android Studio. I've just noticed Gradle has released version 2.12 and according to the release notes the scripts should compile up to 20% faster.
