gradle-dependency-graph-generator-plugin

Gradle plugin that lets you visualize your dependencies in a graph.

Set up

Gradle 3.3 or higher is required.

buildscript {
  repositories {
    mavenCentral()
  }
  dependencies {
    classpath "com.vanniktech:gradle-dependency-graph-generator-plugin:0.8.0"
  }
}

apply plugin: "com.vanniktech.dependency.graph.generator"

Note that this plugin can be applied at the root of the project or at a specific project. Both cases will just work.

Snapshot

buildscript {
  repositories {
    maven { url "https://oss.sonatype.org/content/repositories/snapshots" }
  }
  dependencies {
    classpath "com.vanniktech:gradle-dependency-graph-generator-plugin:0.9.0-SNAPSHOT"
  }
}

apply plugin: "com.vanniktech.dependency.graph.generator"

Usage

By default, this plugin provides two reporting tasks:

generateDependencyGraph	generateProjectDependencyGraph
Generates a complete dependency graph in build/reports/dependency-graph/	Generates a dependency graph of the project modules in build/reports/project-dependency-graph/

Source project: vanniktech/Emoji

The graphs are generated in .png, .svg & .dot format.

There are extension points to be able to generate graphs which only include some dependencies and their transitive ones. The trick is to hook a Generator in over the dependencyGraphGenerator extension. Note that this is extremely experimental and will likely change between releases. It's still fun though.

Generator Example

We only want to show which Jetbrains libraries we're using.

import com.vanniktech.dependency.graph.generator.DependencyGraphGeneratorPlugin
import guru.nidi.graphviz.attribute.Color
import guru.nidi.graphviz.attribute.Style

plugins.apply(DependencyGraphGeneratorPlugin)

dependencyGraphGenerator {
  generators {
    jetbrainsLibraries {
      include = { dependency -> dependency.getModuleGroup().startsWith("org.jetbrains") } // Only want Jetbrains.
      children = { true } // Include transitive dependencies.
      dependencyNode = { node, dependency -> node.add(Style.FILLED, Color.rgb("#AF1DF5")) } // Give them some color.
    }
  }
}

import com.vanniktech.dependency.graph.generator.DependencyGraphGeneratorExtension
import com.vanniktech.dependency.graph.generator.DependencyGraphGeneratorPlugin
import guru.nidi.graphviz.attribute.Color
import guru.nidi.graphviz.attribute.Style

plugins.apply(DependencyGraphGeneratorPlugin::class.java)

configure<DependencyGraphGeneratorExtension> {
  generators.create("jetbrainsLibraries") {
    include = { dependency -> dependency.moduleGroup.startsWith("org.jetbrains") } // Only want Jetbrains.
    children = { true } // Include transitive dependencies.
    dependencyNode = { node, dependency -> node.add(Style.FILLED, Color.rgb("#AF1DF5")) } // Give them some color.
  }
}

This will generate a new task generateDependencyGraphJetbrainsLibraries which when run will yield this graph:
