Gradle find unused dependencies

This is a follow-up to The proper care and feeding of your Gradle buildin which I wrote about how to use the Dependency Analysis Gradle Plugin to help maintain a healthy build for your Android, Java, and Kotlin projects. In this first of a series of posts, we will discuss how that plugin works. To begin, we will take a look at bytecode analysis with the ASM library, and how gradle find unused dependencies is essential in the detection of unused dependencies, gradle find unused dependencies.

Provides advice for managing dependencies and other applied plugins. Dependencies declared on the wrong configuration api vs implementation vs compileOnly , etc. These side effects are currently mostly undocumented internal behaviors, but they may be interesting for some advanced users. In addition to the dependency-related advice see above , DAGP provides other advice to help maintain your "build health. Subprojects "modules" that unnecessarily use the Android plugin, and could instead by "normal" JVM libraries. Please see the wiki for information on the versions of Gradle, the Android Gradle Plugin, etc.

Gradle find unused dependencies

You can add dependencies and view them in the diagram. Any dependency added to the project is managed by Gradle. The best way to add or manage a dependency is in the build. From the context menu, select Add Maven artifact dependency. The Maven Artifact Search window opens. In the Maven Artifact Search window, in the search field, start typing the name of your dependency. In the list of results select the one you need and click Add. Reload your project. If you add a dependency configuration of the source set , it will be displayed in the Gradle tool window as well. You can work with Gradle dependencies in the diagram format. It might be helpful when you have a large project and want to see the whole picture of how dependencies including the transitive ones are connected inside the project. In the Gradle tool window, select a project, on the toolbar, click or select the Show Dependencies option from the context menu.

Any dependency added to the project is managed by Gradle.

.

In Gradle dependencies are libraries required to build your code. Each of these libraries may have their own dependencies, adding transitive dependencies to your project. This structure is called the Gradle dependency tree , with its own rules on dependency conflict resolution and more. Dependency configurations can inherit from each other. When a dependency configuration inherits from a parent configuration, it gets all the dependencies of the parent.

Gradle find unused dependencies

In June, , they have released the 4. They have also added Android support to unused-dependency. In May Gradle has implemented the Gradle lint plugin for finding and removing unwanted dependency. The Gradle Lint plugin is a pluggable and configurable linter tool for identifying and reporting on patterns of misuse or deprecations in Gradle scripts and related files. This plugin has various rules. Unused Dependency Rule is one of them. It has three specific characteristics. For an enterprise build, we recommend defining the lint rules in a init.

Packages 0 No packages published. You can see the analysis in its full glory at asm. In the Maven Artifact Search window, in the search field, start typing the name of your dependency. Any dependency added to the project is managed by Gradle. You can get a sense for the things that matter from the parameter names, however. You can change the size of a diagram, export it to a file, see only a part of the diagram you are interested in, and so on. To know if a dependency is used during compilation, we must know two basic things, fundamentally:. View the diagram structure. You can change the visibility level and, for example, view dependencies that have a specific scope compile, test, and so on. These two inputs are fed into the DependencyMisuseTask forgive me, I am often colorful in my naming conventions , which iterates over all the produced classes and looks to see if they are used by the consumer.

This is a follow-up to The proper care and feeding of your Gradle build , in which I wrote about how to use the Dependency Analysis Gradle Plugin to help maintain a healthy build for your Android, Java, and Kotlin projects. In this first of a series of posts, we will discuss how that plugin works.

Basic configuration. It does do some limited analysis of runtime dependencies such as noting if a dependency provides Java ServiceLoader s , but otherwise elides this domain. Harshal Rembhotkar - Feb It will become hidden in your post, but will still be visible via the comment's permalink. Reload to refresh your session. Use the context menu to zoom in and out, move canvas, change layout, and export part of the diagram into an image. Are you sure you want to hide this comment? For more information about available options and icons in the Dependency Analyzer window, refer to the reference section. Dependencies declared on the wrong configuration api vs implementation vs compileOnly , etc. Instead, every class reference is fully-qualified at the use-site. You signed out in another tab or window. Knowing if a dependency is used for compilation Not to belabor the point, but this is a complex question. In future posts, you can expect discussions of source code parsing with ANTLR, introspecting jars for capabilities such as service loading and annotation processing, dependency management with Gradle APIs, and more. To know if a dependency is used during compilation, we must know two basic things, fundamentally: What does the dependency produce? Add to your project and use.
