Dagger Versions

Dagger release artifacts

Dagger’s release artifacts can be found at https://repo1.maven.org/maven2/com/google/dagger/.

The release notes for each version can be found at https://github.com/google/dagger/releases.

Dagger HEAD-SNAPSHOT artifacts

Dagger’s HEAD-SNAPSHOT artifacts can be used to try out the latest Dagger changes at HEAD. Unlike the Dagger release artifacts, the HEAD-SNAPSHOT artifacts are updated on each commit to the Dagger codebase.

Dagger’s HEAD-SNAPSHOT artifacts can be found at https://central.sonatype.com/repository/maven-snapshots/com/google/dagger/.

We don’t recommended using the HEAD-SNAPSHOT artifacts in production, but it can be used to test out, verify, or just give feedback on features that are not yet released.

Dagger HEAD-SNAPSHOT setup (for Gradle users)

The setup for using the HEAD-SNAPSHOT version can be a bit tricky, so this section walks you through it.

First, replace all of your Dagger dependencies with the HEAD-SNAPSHOT version. For example:

dependencies {
    implementation "com.google.dagger:dagger:HEAD-SNAPSHOT"
    annotationProcessor "com.google.dagger:dagger-compiler:HEAD-SNAPSHOT"
}

Next, update your plugin and project repositories to include the Sonatype snapshot url (see https://central.sonatype.org/publish/publish-portal-snapshots/#consuming-via-gradle). This usually goes in your top-level build.gradle file. For example:

// top-level build.gradle file
buildscript {
    repositories {
        maven {
            url "https://central.sonatype.com/repository/maven-snapshots"
        }
    }
}
allprojects {
    repositories {
        maven {
            url "https://central.sonatype.com/repository/maven-snapshots"
        }
    }
}

Finally, due to Gradle’s versioning rules, you’ll also want to add a resolution strategy to ensure the HEAD-SNAPSHOT is not accidentally replaced by a numbered version of Dagger in your transitive dependencies. This setup usually goes in your application-level build.gradle file. For example:

// app-level build.gradle file
configurations.all {
    resolutionStrategy.eachDependency { DependencyResolveDetails details ->
        if (details.requested.group == 'com.google.dagger') {
            details.useVersion "HEAD-SNAPSHOT"
        }
    }
}
