有没有办法在 angular.json 中扩展配置

在构建Angular 6应用程序时，我需要同时指定两件事:

• If it's production or development build
• The locale I'm using

在我的angular.json美元里，我有:

"build": {
  ...
  "configurations": {
    "production": {
      "fileReplacements": [
        {
          "replace": "src/environments/environment.ts",
          "with": "src/environments/environment.prod.ts"
        }
      ],
      "optimization": true,
      "outputHashing": "all",
      "sourceMap": false,
      "extractCss": true,
      "namedChunks": false,
      "aot": true,
      "extractLicenses": true,
      "vendorChunk": false,
      "buildOptimizer": true
    },
    "pl": {
      "fileReplacements": [
        {
          "replace": "src/assets/i18n/translations.json",
          "with": "src/assets/i18n/pl.json"
        }
      ]
    },
    "en": {
      "fileReplacements": [
        {
          "replace": "src/assets/i18n/translations.json",
          "with": "src/assets/i18n/en.json"
        }
      ]
    }
  }
}

But when I'm doing ng build --configuration=en --configuration=production I'm getting an error Configuration 'en,production' could not be found. I understand it means you can specify only 1 configuration at a time.

This means I need to create separate en, pl, productionEn, productionPl configurations. Though not the cleanest pattern, I can live with that.

"build": {
  ...
  "configurations": {
    "production": {
      "fileReplacements": [
        {
          "replace": "src/environments/environment.ts",
          "with": "src/environments/environment.prod.ts"
        }
      ],
      "optimization": true,
      "outputHashing": "all",
      "sourceMap": false,
      "extractCss": true,
      "namedChunks": false,
      "aot": true,
      "extractLicenses": true,
      "vendorChunk": false,
      "buildOptimizer": true
    },
    "pl": {
      "fileReplacements": [
        {
          "replace": "src/assets/i18n/translations.json",
          "with": "src/assets/i18n/pl.json"
        }
      ]
    },
    "en": {
      "fileReplacements": [
        {
          "replace": "src/assets/i18n/translations.json",
          "with": "src/assets/i18n/en.json"
        }
      ]
    },
    "productionPl": {
      "fileReplacements": [
        {
          "replace": "src/environments/environment.ts",
          "with": "src/environments/environment.prod.ts"
        },
        {
          "replace": "src/assets/i18n/translations.json",
          "with": "src/assets/i18n/pl.json"
        }
      ],
      "optimization": true,
      "outputHashing": "all",
      "sourceMap": false,
      "extractCss": true,
      "namedChunks": false,
      "aot": true,
      "extractLicenses": true,
      "vendorChunk": false,
      "buildOptimizer": true
    },
    "productionEn": {
      "fileReplacements": [
        {
          "replace": "src/environments/environment.ts",
          "with": "src/environments/environment.prod.ts"
        },
        {
          "replace": "src/assets/i18n/translations.json",
          "with": "src/assets/i18n/en.json"
        }
      ],
      "optimization": true,
      "outputHashing": "all",
      "sourceMap": false,
      "extractCss": true,
      "namedChunks": false,
      "aot": true,
      "extractLicenses": true,
      "vendorChunk": false,
      "buildOptimizer": true
    }
  }
}

但我不能忍受的是将整个production配置内容复制并粘贴到productionEn和productionPl中.如果我添加更多的区域设置，或者我想在构建过程中指定的第三个独立方面，这个模式将成为一个需要维护的噩梦.不幸的是，这似乎是Angular团队在他们的documentation个项目中推荐的模式.

Is there a way to tell Angular CLI that productionEn extends production, so to not duplicate the same configuration code multiple times? Something like the code below:

"build": {
  ...
  "configurations": {
    "production": {
      (...)
    },
    "pl": {
      "extends": "production",
      (...)
    },
    "en": {
      "extends": "production",
      (...)
    }
  }
}
