Angular 17中@angular-builders/custom-webpack的Schema验证错误求助

1. 修复Schema验证错误（customWebpackConfig额外属性） #

报错核心原因是Angular 17版本中，@angular-builders/custom-webpack的配置字段位置调整，customWebpackConfig必须嵌套在builderOptions下，不能直接放在options根层级。

修改你的angular.json文件：

• 调整build任务配置：

"build": {
  "builder": "@angular-builders/custom-webpack:browser",
  "options": {
    "outputPath": "dist/new_project_mc",
    "index": "src/index.html",
    "polyfills": ["zone.js"],
    "tsConfig": "tsconfig.app.json",
    "inlineStyleLanguage": "scss",
    "assets": ["src/favicon.ico", "src/assets"],
    "styles": ["src/styles.scss"],
    "scripts": [],
    "builderOptions": {
      "customWebpackConfig": {
        "path": "./webpack.config.js"
      }
    }
  },
  // 其余production/development配置保持不变
}

• 调整serve任务配置：

"serve": {
  "builder": "@angular-builders/custom-webpack:dev-server",
  "options": {
    "builderOptions": {
      "customWebpackConfig": {
        "path": "./webpack.config.js"
      }
    },
    "configurations": {
      "production": {
        "buildTarget": "new_project_mc:build:production"
      },
      "development": {
        "buildTarget": "new_project_mc:build:development"
      }
    },
    "defaultConfiguration": "development"
  }
}

2. 处理"不支持schematics"提示 #

@angular-builders/custom-webpack从v17版本起，官方不再提供schematics支持，因此用ng add安装时会出现该提示，属于正常情况。无需额外处理，完成上述angular.json配置后即可正常使用。

3. 额外兼容性建议 #

你的package.json中@angular-architects/module-federation版本为18.0.4，高于当前Angular 17版本，可能引发潜在兼容性问题。建议降级至17.x版本，执行命令：

npm install @angular-architects/module-federation@17 --save-dev
