当我想用 47 个创建的实体编译我的 jhipster 时，需要很长时间（在 55 分钟到 1h15 之间）。

[INFO] BUILD SUCCESS
[INFO] ----------------------------------------------- -------------------------
[INFO] Total time: 58:38 min
[INFO] Finished at: 2020-03-09T18: 47: 16 + 01: 00

使用的命令是：mvnw clean install package -DskipTests -Pprod

需要时间的似乎是 webpack：

[INFO] > npm run webpack -- --config webpack/webpack.prod.js --profile  
[INFO]  
[INFO]  
[INFO] > mybusiness@2.0.7 webpack C:\dev\workspace-appli\mybusiness  
[INFO] > node --max_old_space_size=8096 node_modules/webpack/bin/webpack.js "--config"   "webpack/webpack.prod.js" "--profile"  
[INFO]  
[ERROR] (node:18144) DeprecationWarning: Tapable.plugin is deprecated. Use new API on `.hooks` instead  
[INFO] Hash: d1f575c068c7812cf12c  
[INFO] Version: webpack 4.42.0  
[INFO] Time: 1586626ms

在我的 package.json 中： 

- "webpack:build:main": "npm run webpack -- --config webpack/webpack.dev.js --env.stats=minimal",   
- "webpack:build": "npm run cleanup && npm run webpack:build:main",  
- "webpack:prod:main": "npm run webpack -- --config webpack/webpack.prod.js --profile",  
- "webpack:prod": "npm run cleanup && npm run webpack:prod:main && npm run clean-www",  
- "webpack": "node --max_old_space_size=8096 node_modules/webpack/bin/webpack.js"

我必须将参数 (max_old_space_size) 传递给 8GB，因为我有一个 4GB 的外存

我的版本： 

Jhipster :  
-   "generator-jhipster": "5.7.0"  
npm version :

      ares: '1.14.0',

mvnw --version

你知道如何优化编译吗？1 小时编译似乎异常长。
