Gradle plugin to discover dependency updates

branch: master
README.md

Gradle Versions Plugin

In the spirit of the Maven Versions Plugin, this plugin provides a task to determine which dependencies have updates.

Usage

This plugin is available from a Maven repository hosted on GitHub. You can add it to your build script using the following configuration:

apply plugin: 'versions'

buildscript {
  repositories {
    maven { url "https://raw.githubusercontent.com/ben-manes/gradle-versions-plugin/mvnrepo/" }
    mavenCentral()
  }

  dependencies {
    classpath 'com.github.ben-manes:gradle-versions-plugin:0.5-beta-5'
  }
}

The current version is known to work with Gradle versions up to 1.12.

Tasks

dependencyUpdates

Displays a report of the project dependencies that are up-to-date, exceed the latest version found, have upgrades, or failed to be resolved. When a dependency cannot be resolved the exception is logged at the info level.

The revision task property controls the resolution strategy of determining what constitutes the latest version of a dependency. The following strategies are supported:

  • release: selects the latest release
  • milestone: select the latest version being either a milestone or a release (default)
  • integration: selects the latest revision of the dependency module (such as SNAPSHOT)

The strategy can be specified either on the task or as a system property for ad hoc usage:

gradle dependencyUpdates -Drevision=release

Another task property outputFormatter controls the report output format. The following values are supported:

  • "plain": format output file as plain text (default)
  • "json": format output file as json text
  • "xml": format output file as xml text, can be used by other plugins (e.g. sonar)
  • a Closure: will be called with the result of the dependency update analysis

You can also set multiple output formats using comma as the separator:

gradle dependencyUpdates -Drevision=release -DoutputFormatter=json,xml

Last, the task property outputDir controls the output directory for the report file(s). The directory will be created if it does not exist. The default value is set to build/dependencyUpdates

gradle dependencyUpdates -Drevision=release -DoutputFormatter=json -DoutputDir=/any/path/with/permission

This displays a report to the console, e.g.

------------------------------------------------------------
: Project Dependency Updates (report to plain text file)
------------------------------------------------------------

The following dependencies are using the latest integration version:
 - backport-util-concurrent:backport-util-concurrent:3.1
 - backport-util-concurrent:backport-util-concurrent-java12:3.1

The following dependencies exceed the version found at the integration revision level:
 - com.google.guava:guava [99.0-SNAPSHOT <- 16.0-rc1]
 - com.google.guava:guava-tests [99.0-SNAPSHOT <- 16.0-rc1]

The following dependencies have later integration versions:
 - com.google.inject:guice [2.0 -> 3.0]
 - com.google.inject.extensions:guice-multibindings [2.0 -> 3.0]
