Gradle

Jenkins Plugin gradle plugin Jenkins Plugin Installs

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.

You can have the Gradle Enterprise Gradle plugin and the Gradle Enterprise Maven extension automatically injected into your Gradle and Maven builds. See Gradle Enterprise integration for more details.

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:

Tool installations

The system provides both automatic installation, which can be performed by directly downloading a Gradle distribution from the Gradle website or executing some shell commands to achieve the same. Besides, for nodes which already have Gradle installed, the tool can be manually configured, by unchecking the Install automatically checkbox and providing the base path (as a GRADLE_HOME environment variable) of the installation.

Usage

The Gradle plugin provides an Invoke Gradle script build step.

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 blank 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.

Build Scan link

Capturing build scans from the console log

If you are not using the Gradle build step described above, or have a Maven build, you can configure to detect published build scans from the console log. For doing so, go to Build Environment and check Inspect build log for published build scans.

Inspect build log for Build Scan

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.

Build Scan link

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 or Maven builds and show them on the build page. In order to do so, wrap your sh or bat steps which invoke Gradle or Maven into withGradle.

For example:

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

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

Build scan in pipeline 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.

Find build scans

Gradle Enterprise integration

The plugin can be configured to inject the Gradle Enterprise Gradle plugin or the Gradle Enterprise Maven extension into any Gradle or Maven build that is executed on the Jenkins server or on any of its connected agents. To achieve this, the plugin installs various files on each agent depending on the configuration via the global options in the Manage Jenkins/Configure System section.

The same auto-injection behavior is available for the Common Custom User Data Gradle plugin and the Common Custom User Data Maven extension.

Note - The configuration applies to all builds on all connected agents matching the specified label criteria, or all in case no label criteria are defined.

Enable auto-injection

The auto-injection is split into three levels to have fine-grained control over the enablement of this feature.

Global

To globally enable the auto-injection, click the Enable auto-injection checkbox in the Gradle Enterprise integration section of the global options in the Manage Jenkins/Configure System section. Next set the URL of the Gradle Enterprise instance to which the build scans should be published to.

Enable auto-injection

Gradle

To enable the auto-injection for Gradle builds, set the desired Gradle Enterprise Gradle plugin version in the Gradle Enterprise Gradle plugin version field in the Gradle settings section of the configuration form.

Gradle settings

Optionally set the desired version of the Common Custom User Data Gradle plugin to be used.

Maven

To enable the auto-injection for Maven builds, click the Enable Gradle Enterprise Maven extension auto-injection checkbox in the Maven settings section of the configuration form.

Maven settings

Optionally click the Enable Common Custom User Data Maven extension auto-injection checkbox to enable the auto-injection of the Common Custom User Data Maven Extension.

To see which versions are injected, refer to Auto-injection compatibility.

Warning - Maven injection only works if MAVEN_OPTS is not configured as a global environment variable.

Disable auto-injection

Disabling the auto-injection requires that all Gradle Enterprise resources are cleaned up from the agents. To achieve this, the Gradle or Maven injections must be disabled individually (see the following sections). This triggers a cleanup of the resources. If the auto-injection should be disabled globally, then uncheck the Enable auto-injection checkbox as well.

Gradle

To disable the auto-injection for Gradle builds, remove the Gradle Enterprise Gradle plugin version in the Gradle settings section of the configuration form.

Maven

To disable the auto-injection for Maven builds, uncheck the Enable Gradle Enterprise Maven extension auto-injection checkbox in the Maven settings section of the configuration form.

Control auto-injection based on node labels

Auto-injection can be enabled or disabled based on specific node labels. To enable auto-injection only on specific nodes, add the desired labels to the Gradle auto-injection enabled nodes list for Gradle or Maven auto-injection enabled nodes for Maven. To disable auto-injection on specific nodes, add the desired labels to the Gradle auto-injection disabled nodes list for Gradle or Maven auto-injection disabled nodes for Maven.

The disabled labels list will take precedence over the enabled labels list.

Configuration options

The following sections list all available configuration options which can be set via the configuration form.

Common configuration options

Enable auto-injection
Globally enable auto-injection.

Gradle Enterprise server url
The URL of the Gradle Enterprise instance.

Allow untrusted server
Whether to allow publishing to a server with a self-signed certificate.

Gradle Enterprise access key
The access key for authenticating with the Gradle Enterprise server. The access key is stored encrypted within the Jenkins instance. During the job execution, the access key is decrypted and set as GRADLE_ENTERPRISE_ACCESS_KEY environment variable. Refer to the Gradle Enterprise Gradle plugin manual and the Gradle Enterprise Maven Extension manual for more details about this configuration.

Gradle specific configuration options

Enables auto-injection for Gradle builds and defines which version of the Gradle Enterprise Gradle plugin to use.

Common Custom User Data Gradle plugin version
Defines which version of the Common Custom User Data Gradle plugin to use.

Gradle plugin repository url
The URL of the repository to use to resolve the Gradle Enterprise Gradle plugin and the Common Custom User Data Gradle plugin. This is required if the Jenkins agents are not able to access the Gradle Plugin Portal.

Gradle auto-injection enabled nodes
A list of node labels on which the Gradle Enterprise Gradle plugin or Common Custom User Data Gradle plugin injection should be enabled. By default, all nodes are enabled.

Gradle auto-injection disabled nodes
A list of node labels on which the Gradle Enterprise Gradle plugin or Common Custom User Data Gradle plugin injection should be disabled. By default, all nodes are enabled.

Maven specific configuration options

Enable Gradle Enterprise Maven extension auto-injection
Enables auto-injection for Maven builds and injects Gradle Enterprise Maven extension.

Enable Common Custom User Data Maven extension auto-injection
Enables auto-injection of Common Custom User Data Maven extension.

Maven auto-injection enabled nodes
A list of node labels where the Gradle Enterprise Maven extension or Common Custom User Data Maven extension injection should be enabled. By default, all nodes are enabled.

Maven auto-injection disabled nodes

Auto-injection compatibility

The following sections list the compatibility of the plugin with the Gradle Enterprise version based on the given build tool in use.

For Gradle builds

For Gradle builds the version used for the Gradle Enterprise Gradle plugin is defined in the Gradle Enterprise Gradle plugin version field in the Gradle settings section of the configuration form. See Enable auto-injection for details. The compatibility of the specified version with Gradle Enterprise can be found here.

For the optional Common Custom User Data Gradle plugin which is defined the same form, you can see the compatibility of the specified version with the Gradle Enterprise Gradle plugin here.

For Maven builds

For Maven builds the version of the Gradle Enterprise Maven extension is bundled into the plugin, meaning that the user can’t change what version is injected into the Maven build.

The following table shows the compatibility of the plugin version with Gradle Enterprise:

Jenkins Gradle Plugin version
