grunt-maven

npm tasks for grunt-maven-plugin.

grunt-maven-plugin NPM tasks power Maven+Grunt integrated workflow. These tasks depend on properties file produced by grunt-maven-plugin, which contains paths and options derived from projects pom.xml.

Getting started

Add plugin dependency to your package.json:

"devDependencies": {
  "grunt-maven": "~1.1.0",
}

Load tasks in Gruntfile:

grunt.loadNpmTasks('grunt-maven');

mavenPrepare task

Overview

This tasks role is to copy raw sources from Maven webapp sources to target-grunt, where Grunt tasks will be executed. In your project's Gruntfile, add a section named mavenPrepare to the data object passed into grunt.initConfig().

grunt.initConfig({
  mavenPrepare: {
    options: {
      resources: ['**']
    },
    dev: {
    },
    prod: {
      resources: ['**', '!dev/**']
    }
  },
});

Options

options.resources

Type: Array

List of patterns that will be evaluated using minimatch to choose resources that will be copied from Maven webapp to target-grunt.

mavenDist task

Overview

mavenDist task copies artifacts produced by Grunt (less -> css, minified JS) from target-grunt to target-grunt/dist and from target-grunt to Maven WAR directory.

grunt.initConfig({
  mavenDist: {
    options: {
      warName: 'war',
      deliverables: ['**', '!non-deliverable.js'],
      gruntDistDir: 'dist'
    },
    dev: {
      warName: 'war-dev'
    }
  },
});

Options

options.warName

Type: String

Name of WAR directory, residing in /target/, to which all deliverables will be copied.

options.deliverables

Type: Array

List of patterns that will be evaluated using minimatch to choose deliverables that will be copied from target-grunt/ to target-grunt/dist and to WAR.

options.workingDirectory

Type: String Default: Directory where gruntfile is located

Deliverable patterns will be matched relative to this path, and all returned filepaths will also be relative to this path.

options.gruntDistDir

Type: String Default: dist

Name of directory residing in target-grunt, where all deliverables will be copied.

Using maven* tasks

Each defined task that wants to operate on resources from Maven, should start with mavenPrepare and end with mavenDist, for example:

grunt.registerTask('default', ['mavenPrepare', 'jshint', 'karma', 'less', 'uglify', 'mavenDist']);

• prepare environment in target-grunt
• run all Grunt specific tasks in target-grunt
• copy deliverables to WAR

watch

Using grunt-contrib-watch can be very useful to create good development environment, just register whatever task you should need to run on resources change, using properties generated by grunt-maven-plugin to obtain watch path:

grunt.initConfig({
    gruntMavenProperties: grunt.file.readJSON('grunt-maven.json'),

    watch: {
        maven: {
            files: ['<%= gruntMavenProperties.filesToWatch %>'],
            tasks: 'default'
        }
    }
});

gruntMavenProperties.filesToWatch evaluates to /src/main/webapp/statics_dir/**. If you need to exclude some resources from being watched (although you probably shouldn't need to), use gruntMavenProperties.directoryToWatch. This is simply path to directory without globing pattern appended, in our case: /src/main/webapp/statics_dir.
