grunt-maven-tasks

Grunt maven tasks - install artifacts locally or deploy and release articats to maven repository.

Getting Started

This plugin requires Grunt ~0.4.1

If you haven't used Grunt before, be sure to check out the Getting Started guide, as it explains how to create a Gruntfile as well as install and use Grunt plugins. Once you're familiar with that process, you may install this plugin with this command:

npm install grunt-maven-tasks --save-dev

Once the plugin has been installed, it may be enabled inside your Gruntfile with this line of JavaScript:

grunt.loadNpmTasks('grunt-maven-tasks');

Supported Maven Goals

no goal

If no goal is specified, the goal will be set to the target name. This means that the target name must be one of install, deploy or release. For more flexibility with the naming of your targets, and/or having multiple targets with the same goal, specify the goal explicitly.

install

Run the grunt maven task with the goal option set to install.

This tasks packages and installs an artifact to your local maven repository.

deploy

Run the grunt maven task with the goal option set to deploy.

This tasks packages and deploys an artifact to a maven repository.

release task

Run the grunt maven task with the goal option set to release.

This task packages and releases an artifact to a maven repository. It will update the version number in the package.json file to the next development version, and, if this is a git project, it will commit and tag the release.

By default, it will increment the version number using the minor version. This can be overridden in the config section using the mode option.

Run this task with the grunt maven:[your-task-target]:major command to bump the next development version using the major version mode.

Run this task with the grunt maven:[your-task-target]:1.2.0 command to release version 1.2.0.

Run this task with the grunt maven:[your-task-target]:1.2.0:major command to release version 1.2.0 and bump the next development version using the major version mode.

Overview

In your project's Gruntfile, add a section named maven to the data object passed into grunt.initConfig().

grunt.initConfig({
  maven: {
    options: {
      goal: 'deploy',
      groupId: 'com.example',
      url: '<repository-url>',
    },
    src: [ '**', '!node_modules/**' ]
  }
})

Options

options.goal

Type String Default: target name

The maven goal for the target artifact. Valid values are 'deploy' and 'release'. Defaults to the target name

options.groupId

Type: String Required

The maven group id to use when deploying and artifact

options.artifactId

Type: String Default: name found in package.json

The maven artifact id to use when deploying and artifact

options.version

Type: String Default: version found in package.json

The version to use when deploying to the maven repository

options.classifier

Type: String Optional

The classifier to use when deploying to the maven repository

options.mode

Type: String Default: minor

The mode passed to semver.inc to determine next development version.

options.packaging

Type: String Default: zip

The packaging to use when deploying to the maven repository. Will also determine the archiving type. As internally the grunt-contrib-compress plugin is used to package the artifact, only archiving types supported by this module is supported.

options.url

Type: String Required

The url for the maven repository to deploy to.

options.repositoryId

Type: String Optional

The repository id of the repository to deploy to. Used for looking up authentication in settings.xml.

options.type

Type: String Optional

Enables you to choose a different file extension for your artifact besides .zip which is useful when using the Maven WAR-plugin

options.injectDestFolder

Type: String Optional

Enables you to turn off the injection of destination folder inside your artifact allowing you to choose the structure you want by configuring the compress task.

options.commitPrefix

Type: String Optional

Prefix for the commit message when releasing.

Files

Files may be specified using any of the supported Grunt file mapping formats.

Usage Examples

Default Options

In this example, only required options have been specified and the 'goal' is defaulted to the target name.

Running grunt maven:deploy will deploy the artifact to the snapshot-repos folder using the groupId com.example, the artifactId set to the name in package.json and the version set to the version in package.json.

Running grunt maven:release will deploy the artifact to the release-repo folder using the groupId com.example, the artifactId set to the name in package.json and the version set to the version in package.json, but with the -SNAPSHOT suffix removed. The version in package.json will be incremented to the next minor SNAPSHOT version, ie. if it was 1.0.0-SNAPSHOT it will end up at 1.1.0-SNAPSHOT. If this is a git repository, it will also commit and tag the release version, as well as commiting the updated package.json version.

grunt.initConfig({
  maven: {
    options: { groupId: 'com.example' },
    deploy: {
      options: {
        goal: 'deploy',
        url: 'file://snapshot-repo'
      },
      src: [ '**', '!node_modules/**' ]
    },
    release: {
      options: {
        goal: 'release',
        url: 'file://release-repo'
      },
      src: [ '**', '!node_modules/**' ]
    }
  }
})

grunt.registerTask('deploy', [ 'clean', 'test', 'maven:deploy' ]);
grunt.registerTask('release', [ 'clean', 'test', 'maven:release' ]);

The maven task can be configured to support deployment or release of multiple artifacts:

grunt.initConfig({
  maven: {
    deployA: {
      options: {
        goal: 'deploy',
        groupId: 'com.example',
        artifactId: 'myNodeArtifact',
        url: '<repository-url>',
      },
      src: [ '**', '!node_modules/**' ]
    },
    deployB: {
      options: {
        goal: 'deploy',
        groupId: 'com.example',
        artifactId: 'myBrowserArtifact',
        url: '<repository-url>',
      },
      src: [ 'target/browser/**', '!target/browser/node_modules/**' ]
    }
  }
})

Custom Options

In this example, the artifactId has been explicitly set, and the version bumping used when releasing is set to 'patch' level rather than the default 'minor'.

grunt.initConfig({
  maven: {
    options: { groupId: 'com.example', artifactId: 'example-project' },
    deploy: {
      options: { url: 'file://snapshot-repo' },
      src: [ '**', '!node_modules/**' ]
    },
    release: {
      options: { url: 'file://release-repo', mode: 'patch' },
      src: [ '**', '!node_modules/**' ]
    }
  }
})

In order to customize the output archive, please look at the documenations for the grunt-contrib-compress task.
