To be able to build a Gradle plugin youll need to tell your project to use a compile-time dependency on the Gradle API. You can install the plugin to local maven repository via: Then use the plugin under development via: This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository. You can unsubscribe at any time. For example it formalized the concept of a SourceSet and introduces dependency management configurations. To enable build cache pushing, you need to pass environment variables or system properties: To enable build scan publishing, you need to correctly authenticate as documented here. Also it allows Gradle to optimize the build configuration. The usage of the version catalog is possible. Use extensions instead. Has a bill ever failed a house of Congress unanimously? WebWhat it does. Locates the plugin convention object with the given type. Modules can then pick and choose the configurations they need. com.myorg.service-conventions - configures integration tests and checks for mandatory content in a README. Usage See plugin portal. First we create a build.gradle.kts file in the buildSrc directory in the root of our multi-module project and apply the kotlin-dsl plugin: Next we create the conventions plugin with our shared configuration: The id of our new plugin is java-project-conventions and we can use it in our build script for a subproject as: The rest-api project will have all the configuration and tasks from java-library plugin as configured in the java-project-conventions plugin, so we can build it as a Java project. Could someone explain? The last step to use the created convention plugin in the project is to add it to the build.gradle.kts by its name. SpotBugs is an external plugin - external plugins need to be added as implementation dependencies before they can be applied in a convention plugin: The dependency artifact coordinates (GAV) for a plugin can be different from the plugin id. Conventions for publishing GradleX plugins. #deltafi 1.0.2 (29 June 2023) io.github.jcohy.gradle.asciidoctor-conventions The myproject.java-conventions plugin is then applied to the buildSrc build: It is also applied in the subprojects of the root project: For more details on authoring custom Gradle plugins, consult the user manual. Here, we configure the project to publish the plugins using the maven-publish plugin. Because there is a plugin necessary I also need to update the build.gradle.kts of the buildSrc directory (dont forget to also update the libs.versions.toml as done above).

What is the reasoning behind the USA criticizing countries and then paying them diplomatic visits? And at the end replace the content of the build.gradle.kts of Module A and B with: After this change has been done, the build configuration of the root project and also of every submodule is much clearer now. In order for precompiled script plugins to be discovered, the convention-plugins project needs to apply the groovy-gradle-plugin plugin The amount of duplication in the build logic grows even faster. But already there it is not clear from the submodule view, where the configuration is coming from. This approach is based on a Gradle feature Precompiled Script Plugins and this is now a recommend way for sharing build logic accorss modules in larger projects. When applied as a settings plugin alongside the Gradle Enterprise Plugin, this plugin does the following: If the build cache is enabled (via --build-cache or org.gradle.caching=true, see the doc ): Enable the local cache. The use of dynamic Groovy and (its very capable testing and mocking framework) Spock is a very viable and common option. https://github.com/spring-gradle-plugins/gradle-enterprise-conventions-plugin. Its a developers choice as long as the plugin binary can be executed on the JVM. Thanks for contributing an answer to Stack Overflow! In practice you will find that most users are comfortable with the default conventions until theres a good reason to change them e.g. Toolchains resolver using the Foojay Disco API for resolving Java runtimes. WebCompiling convention plugins Things to note Groovy DSL Kotlin DSL You can open this sample inside an IDE using the IntelliJ native importer or Eclipse Buildship .

As a developer of Gradle plugins you have full freedom in defining and organizing code. Plugins The AndroidFeatureConventionPlugin applies the same plugins from above plus org.jetbrains.kotlin.kapt because all features modules in NiA use libraries like Hilt which require KAPT for code generation. To learn more, see our tips on writing great answers. A change in buildSrc causes the whole project to become out-of-date. The submodule cannot exist without root configuration. Just the things that your module needs. The first thing we see here is some files that have configuration logic that different plugins can apply, like AndroidCompose.kt , KotlinAndroid.kt and Flavor.kt. I am currently implementing it in our project and have only applied the plugins to a subset of modules. [] Keep in mind that some of the libraries might pull in a huge graph of transitive dependencies when declared through Gradles dependency management system.

I have a question about using a plugin declared in a version-catalog inside a You should consider using the same technique when designing your own plugins. When applied as a settings plugin alongside the Gradle Enterprise Plugin, this plugin does the following: If the build cache is enabled (via --build-cache or org.gradle.caching=true, see the doc ): Enable the local cache. Thats especially the case when code of a plugin is executed during the configuration phase of the build lifecycle e.g. You will be able separate common logic into completely independent bits, which should be easier to maintain. Some people would even write build configuration from scratch. Convention plugins are a solution for sharing build configuration between submodules, as titled by Gradle itself. WebWhen designing Gradle plugins always be aware of the impact on the end user. organizing and structuring plugin logic, testing and debugging plugin code as well as publishing the plugin artifact to a repository for consumption. For more details about included builds, see Composing Builds chapter. In a product oriented project, it will be one app module and many library modules. The Gradle profiler can help with automating build scan generation and gathering more low-level information. The result is your feature modules build scrips mostly end up looking like this, which is how they should. to use Codespaces. Gradle Plugins Gradle convention plugins We also declare a subproject that will contain our convention plugins. When the team is developing white-label apps, it will be many apps on top of many library modules. For a Groovy plugin we place the file in src/main/groovy, for a Kotlin plugin we place it in src/main/kotlin. WebA convention plugin composes existing core plugins and community plugins and configures them with your own conventions - e.g. Assuming it is attached to a Project object, an extension allows you to add project.foo.someMethod, but not project.someMethod. Extensions are the newer concept and have largely replaced conventions. Modules can then pick and choose the configurations they need. Please You explicitly apply different convention plugins to different modules. Refactor your Gradle build configuration with convention plugins December 10, 2021, updated December 11, 2021 | 7 min read Many Android projects contain more than one module (subproject). Is there a distinction between the diminutive suffixes -l and -chen? The third option is a bit better in terms of code duplication, but buildSrc is not great because it invalidates build cache every time you make changes to anything inside it, effectively causing a clean build with every change. Others would simply copy-paste some existing module and change it. This is a limitation that hopefully is removed at some time. As an example, lets say an organization produces two types of Java software - services and libraries. Also it allows Gradle to optimize the build configuration. WebPlugins add new tasks (e.g. Toolchains resolver using the Foojay Disco API for resolving Java runtimes. The extension class can define arbitrary methods. resolving dependencies by iterating over them, making HTTP calls or writing to files. Gradle plugins Might be useful when writing custom plugins. Plugins In most cases it will support the use case you are trying to support with your plugin. We read every piece of feedback, and take your input very seriously. Gradle Convention Plugins Applying a plugin version inside a convention plugin shaunek (Shaun Ek) February 7, 2022, 2:00pm 1 I would like to know how to have a convention plugin that applies some other plugins but Im having a really hard time finding information about this online. With this it is difficult to develop reusable modules (like libraries) or group multiple submodules with different purpose in one project,withoutbloatingtheconfigurationwithif-elseblocks. The dependency report does not render dependencies declared for the classpath configuration of the build script, effectively the classpath of the declared plugins and their transitive dependencies. You could try using it for new projects. Use case Gradle plugins can provide users with sensible defaults and standards (conventions) in a certain context. If you need more information about why this is necessary, have a look in the Gradle documentation regarding usage of plugins in pre-compiled scripts. The following code example shows how to apply a plugin from another one, so-called plugin composition: For inspiration, here are two open-source plugins that apply the concept: Gradle doesnt take a stance on the programming language you should choose for implementing a plugin. There is no relation to the root project configuration inside the submodule. in its build.gradle.kts file: In this sample we are targeting a multi-repo setup. In turn those dependencies might conflict with other versions of the same library being resolved from other plugins and might lead to unexpected runtime behavior. The actual inner workings - the "how" - is completely hidden from the end user. Search Gradle plugins. For achieving this goal there are 2 ways available: Using the buildSrc directory for setup of a convention plugin is the easiest way and a good starting point. if you have to work with a legacy project. The Java Base plugin just provided un-opinionated functionality and general purpose concepts. With this the first problem of the initial build configuration is solved. Gradle offers functionality for extracting build logic/configuration to a so called Convention Plugin. a regular build script. Gradle Plugins Modules can then pick and choose the configurations they need. Work fast with our official CLI. sign in plugin It is a conceptual term to distinguish plugins that configure existing functionality from plugins that add new You can develop both plugins within the same project and ship their compiled classes and identifiers with the same binary artifact. Convention mapping is the most powerful solution that's currently available to solve the "deferred configuration" problem, but it is considered an internal feature. There is an issue with IDEA that causes wrong gradle wrapper to be used when running tests from IDE. When working with a Gradle multi-modul project, there are 2 places for configuration of build related tasks: In the root build.gradle.kts there are mainly configurations, which are related to the root project itself e.g. Convention, and the properties and methods of the convention object become available as properties and methods of Convention Gradle - Plugins The build is then included in the root projects settings file as seen in the above snippet. The idea is to put all your build logic into special project, which you can call build-logic. As you can see there is no reference to the plugins section of the version catalog but the library one. Plugin Latest Version; org.jetbrains.compose JetBrains Compose Gradle plugin for easy configuration. Generally, there is nothing wrong with this. When we have a multi-module project in Gradle we sometimes want to have dependencies, task configuration and other settings shared between the multiple modules. The build is then included in the root projects settings file as seen in the above snippet. 587), The Overflow #185: The hardest part of software is requirements, Starting the Prompt Design Site: A New Home in our Stack Exchange Neighborhood, Temporary policy: Generative AI (e.g., ChatGPT) is banned, Testing native, sponsored banner ads on Stack Overflow (starting July 6). WebThe shared convention plugin myproject.java-conventions is implemented in an included build called build-conventions . This type of plugin can be written as a build script using the Groovy or Kotlin DSL with a filename ending with .gradle or .gradle.kts. Alternatively, it can also be included at build time via command line parameter: ./gradlew --include-build build-logic. An extension is an instance of an arbitrary (typically user-defined) class that's attached to the build model under a user-defined name. WebThe plugins. plugin Since each extension has its own namespace (foo in this case), the chance of name collisions is greatly reduced (compared to conventions). Common pattern that people do here, is either putting the code into subprojects {} block of root build.gradle file, or put configuration logic into a separate gradle file and apply it to specific module via apply from: 'file.gradle'.
