如何使用咕unt目標

Question

我的Gruntfile.js類似於：

 'use strict';

module.exports = function(grunt) {
    grunt.initConfig({
        grunt.config.set('targ', grunt.option('target'));
        cachebuster: {
            build: {
                options: {
                    basedir: 'WebContent',
                    formatter: function(hashes) {
                        var json = {};
                        for (var filename in hashes) {
                            json["/" + filename] = hashes[filename];
                        }
                        return JSON.stringify(json);
                    }
                },
                src: [ 'WebContent/assets/**/*.js', 'WebContent/assets/**/*.css' ],
                dest: 'src/main/resources/cachebusters.json'
            }
        }
    });

// These plugins provide necessary tasks.
grunt.loadNpmTasks('grunt-cachebuster');    

// Default task.
grunt.registerTask('default', ['cachebuster']);

};

我想基於dev更改dest的位置或部署命令行參數。

也就是說，如果命令行arg是dev，那么dest：'cachebuster.json'如果部署了命令行arg，則dest：'src / main / resources / cachebuster.json'

我該如何實現？

您可以嘗試以下代碼塊。 默認情況下，如果不提供任何參數，第一個目標將被執行（在這種情況下為dev）：

cachebuster: {
  dev: {
    options: {
      basedir: 'WebContent',
      formatter: function(hashes) {
        var json = {};
        for (var filename in hashes) {
          json["/" + filename] = hashes[filename];
        }
        return JSON.stringify(json);
      }
    },
    src: ['WebContent/assets/**/*.js', 'WebContent/assets/**/*.css'],
    dest: 'src/main/resources/cachebusters.json'
  },
  deploy: {
    options: {
      basedir: 'WebContent',
      formatter: function(hashes) {
        var json = {};
        for (var filename in hashes) {
          json["/" + filename] = hashes[filename];
        }
        return JSON.stringify(json);
      }
    },
    src: ['WebContent/assets/**/*.js', 'WebContent/assets/**/*.css'],
    dest: 'src/main/resources/cachebusters.json'
  }
}

如果要跨目標共享選項，請使用以下代碼塊。

cachebuster: {
  options: {
    basedir: 'WebContent',
    formatter: function(hashes) {
      var json = {};
      for (var filename in hashes) {
        json["/" + filename] = hashes[filename];
      }
      return JSON.stringify(json);
    }
  },
  dev: {
    src: ['WebContent/assets/**/*.js', 'WebContent/assets/**/*.css'],
    dest: 'src/main/resources/cachebusters.json'
  },
  deploy: {
    src: ['WebContent/assets/**/*.js', 'WebContent/assets/**/*.css'],
    dest: 'src/main/resources/cachebusters.json'
  }
}
