Dagger 2

A fast dependency injector for Android and Java.

About Google's Fork

Dagger 2 is a compile-time evolution approach to dependency injection. Taking the approach started in Dagger 1.x to its ultimate conclusion, Dagger 2.0 eliminates all reflection, and improves code clarity by removing the traditional ObjectGraph/Injector in favor of user-specified @Component interfaces.

This github project represents the Dagger 2 development stream. The earlier project page (Square, Inc's repository) represents the earlier 1.0 development stream.
Both versions have benefitted from strong involvement from Square, Google, and other contributors.

Dagger 2's main documentation website can be found here.

Status

  • Release Version: 2.0.1
  • Snapshot Version: 2.1-SNAPSHOT

Dagger is currently in active development, primarily internally at Google, with regular pushes to the open-source community. Snapshot releases are auto-deployed to sonatype's central maven repository on a clean build with the version 2.1-SNAPSHOT.

Documentation

You can find the dagger documentation here which has extended usage instructions and other useful information. Substantial usage information can be found in the API documentation.

You can also learn more from the original proposal, this talk by Greg Kick, and on the dagger-discuss@googlegroups.com mailing list.

Installation

You will need to include the dagger-2.0.1.jar in your application's runtime. In order to activate code generation and generate implementations to manage your graph you will need to include dagger-compiler-2.0.1.jar in your build at compile time.

In a Maven project, include the dagger artifact in the dependencies section of your pom.xml and the dagger-compiler artifact as either an optional or provided dependency:

<dependencies>
  <dependency>
    <groupId>com.google.dagger</groupId>
    <artifactId>dagger</artifactId>
    <version>2.0.1</version>
  </dependency>
  <dependency>
    <groupId>com.google.dagger</groupId>
    <artifactId>dagger-compiler</artifactId>
    <version>2.0.1</version>
    <optional>true</optional>
  </dependency>
</dependencies>

If you use the beta dagger-producers extension (which supplies parallelizable execution graphs), then add this to your maven configuration:

<dependencies>
  <dependency>
    <groupId>com.google.dagger</groupId>
    <artifactId>dagger-producers</artifactId>
    <version>2.0-beta</version>
  </dependency>
</dependencies>

Download

If you do not use maven, gradle, ivy, or other build systems that consume maven-style binary artifacts, they can be downloaded directly via the Maven Central Repository.

Developer snapshots are available from Sonatype's snapshot repository, and are built on a clean build of the GitHub project's master branch.
