Jenkins Gradle Plugin

Description

This plugin adds Gradle Support to Jenkins. Gradle is managed as another tool inside Jenkins (the same way as Ant or Maven), including support for automatic installation and a new build step is provided to execute Gradle tasks.

It also allows detecting Build Scans in arbitrary console logs, for Maven and Gradle builds and display them in the Jenkins UI.

The plugin also allows for injecting Build Scans into both Maven and Gradle builds by setting some environment variables, see Injecting Build Scans.

In order to release this plugin have a look at here.

Configuration

Gradle configuration is performed in the Configure System (before Jenkins 2.0) or Global Tool Configuration (starting in Jenkins 2.0). In both cases these options reside in the Manage Jenkins section.

In the Gradle section provided by this plugin, several installations can be configured:

The system provides both automatic installation, which can be performed by directly downloading from the Gradle web site, extracting a compressed final or executing some shell commands. Besides, for nodes which already has Gradle installed, the tool can by manually configured, by unchecking the Install automatically checkbox and providing the base path (GRADLE_HOME) of the installation.

Usage

The Gradle plugin provides an Invoke Gradle script build step.

The first configuration option is whether to use one of the installation configured in Jenkins (see previous section) of use the Gradle Wrapper which is the Gradle-provided mechanism to "embed" the use of a specific Gradle version in a build, installing it if necessary.

Other configuration options include:

A description to use for the build step.
Switches (options) to provide to the Gradle execution.
Tasks to execute (if blanck the defaults tasks of the build will be invoked).
Path to the build script if different from the root directory of the build.
Name of the build script if different from build.gradle.

If a Gradle Build Scan is produced during a build, then a link to it is added to the build page.

Capturing build scans from console log

If you are not using the provided build scan, you can still configure to detect published (Maven or Gradle) Build Scans from the console log. For doing so, go to Build Environment and check Inspect build log for published Gradle build scans.

If build scans are detected in the console log of a build, a badge will be added to the build page. This works for Build Scans produced by Gradle and Maven builds.

Capturing build scans from Jenkins Pipeline

When using Jenkins pipeline, there is the build step wrapper withGradle which can be used to find the build scans emitted by Gradle builds and show them on the build page. In order to do so, wrap your sh or bat steps which invoke Gradle into withGradle.

For example:

node {
  withGradle {
    sh './gradlew build'
  }
}

This causes the shell output to be highlighted and build scan links, which are emitted, are captured. The captured build scan links are then shown on the build page and in the pipeline steps view.

There is also the findBuildScans() step, which finds the build scans in the complete log of the pipeline job. The withGradle wrapper should be used instead, since it also deals well with parallel output.

Injecting Build Scans

The plugin can be configured to inject Build Scans into any Gradle or Maven build that’s running on the Jenkins server or any of its connected agents.

How it works

This feature works by installing scripts and Jars on each agent depending on the environment variable settings.

If the JENKINSGRADLEPLUGIN_GRADLE_ENTERPRISE_PLUGIN_VERSION environment variable is present, injection is activated for Gradle builds. This causes an init script is installed in the user home of each connected agent. The init script is removed when the environment variable is removed, thus deactivating injection for Gradle builds. If the JENKINSGRADLEPLUGIN_GRADLE_ENTERPRISE_EXTENSION_VERSION environment variable is present, injection is activated for Maven builds. This causes the Gradle Enterprise Maven Extension to be installed on each connected agent, and the MAVEN_OPTS environment variable will be modified so that each Maven process will load the extension. If the environment variable is removed again, the extension is deleted from all agents and the changes to MAVEN_OPTS are reverted.

Configuration options

The following table lists all available configuration options.

Table 1. General variables

Environment variable	Build Tool	Description
JENKINSGRADLEPLUGIN_GRADLE_ENTERPRISE_URL	Both	The URL of the Gradle Enterprise server to publish Build Scans to.
JENKINSGRADLEPLUGIN_GRADLE_ENTERPRISE_ALLOW_UNTRUSTED_SERVER	Both	Whether to allow publishing to a server with a self-signed certificate. Defaults to `false`.
JENKINSGRADLEPLUGIN_GRADLE_ENTERPRISE_EXTENSION_VERSION	Maven	Enables injection for Maven builds.
JENKINSGRADLEPLUGIN_GRADLE_ENTERPRISE_PLUGIN_VERSION	Gradle	Enables injection for Gradle builds and defines which version of the Gradle Enterprise Gradle plugin to use.
JENKINSGRADLEPLUGIN_CCUD_PLUGIN_VERSION	Gradle	Defines which version of the Gradle Enterprise Gradle plugin to use.

In addition to the variables above you might want to set the GRADLE_ENTERPRISE_ACCESS_KEY variable if you’re Gradle Enterprise server requires authentication for publishing Build Scans. Refer to the Gradle Enterprise Gradle plugin manual and the Gradle Enterprise Maven Extension manual for more information.

Limitations

The configuration is based on global environment variables and applies to all builds on the server and all connected agents.
Injecting Build Scans into Maven builds only works in MAVEN_OPTS is not set.

Roadmap

Using the Gradle API for accessing all the Gradle functionalities
Providing a Maven-like or Ivy-like integration
- Multi-project detection
- Adding automatic tests result path detection
- Listing executed tasks with time execution for each task
- Providing a log for each module in a multi-project
