Gradle find unused dependencies

Provides advice for gradle find unused dependencies dependencies and other applied plugins. Dependencies declared on the wrong configuration api vs implementation vs compileOnlyetc. 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 aboveDAGP provides other advice to help maintain your "build health.

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.

Gradle find unused dependencies

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. To begin, we will take a look at bytecode analysis with the ASM library, and how it is essential in the detection of unused dependencies. 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. This is a complex question. And what even is a dependency? It provides a collection of zero or more:. May be external or a separate module in your project. Used dependency. A library required to compile your project, or which your project requires at runtime. Not to belabor the point, but this is a complex question. To know if a dependency is used during compilation, we must know two basic things, fundamentally:. It does do some limited analysis of runtime dependencies such as noting if a dependency provides Java ServiceLoader s , but otherwise elides this domain.

A library required to compile your project, or which your project requires at runtime. Used dependency. You can see the analysis in its full glory at asm.

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. But its latest version 1. B: Many of our engineers are being confused about this plugin as they updated only the version number, nothing else.

Gradle find unused dependencies

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.

Item Description Scope You can see scopes in which every dependency is used in the project. Unnecessary plugins currently only kapt. Last commit date. Generate a diagram. SEO with Next. This issue highlights one such case. Lucas Fugisawa - Feb Provides advice for managing dependencies and other applied plugins Topics android kotlin java groovy scala jvm gradle-plugin. Starting with that jar, we iterate over the class files it contains, visiting each one with an implementation of ASM's ClassVisitor ; in this case MyClassVisitor. In the list of results select the one you need and click Add. Go to file. This is a complex question. We know what the producers produce and what the consumers consume. You can add dependencies and view them in the diagram. This is done by ClassListAnalysisTask which takes as its primary input — you guessed it — a list of class files.

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.

History 1, Commits. It will become hidden in your post, but will still be visible via the comment's permalink. To know if a dependency is used during compilation, we must know two basic things, fundamentally:. You can ask it why:. However, in order to keep this discussion focused, I am deferring discussion of ABI computation to a future article. At the top level are all the dependencies you've declared directly, but below those are the transitive dependencies the top-level or direct dependencies depend on; these are often available for direct use, despite not being declared by your project. Branches Tags. In the Gradle tool window, select a project, on the toolbar, click or select the Show Dependencies option from the context menu. To close the popup, press Escape. Unnecessary plugins currently only kapt. You may be curious why the plugin is emitting or not emitting advice regarding some dependency.
