JHipster Prod Package 期间的 Webpack 失败

Question

我生成了一个普通的 JHipster 微服务网关。随着 JHipster 注册表的运行，我可以使用 ./mvnw 启动它并且它可以工作。我可以使用./mvnw -Pdev package 打包它，并且可以。但是，如果我尝试使用 ./mvnw -Pprod package 打包它，它显然会在 webpack 构建产品步骤中失败。

• JHipster 版本 4.14.0
• 纱线版本​​ 1.3.2
• 节点版本 v6.11.5

此问题与 JHipster 的 workbox-webpack-plugin 依赖关系有关，已在 v4.14.1 release (related commit) 中修复。要在生成的项目中修复它，请进行以下更改：

package.json:

-    "workbox-webpack-plugin": "3.0.0-alpha.3",
+    "workbox-webpack-plugin": "3.0.0-beta.1",

webpack/webpack.prod.js

-        new WorkboxPlugin({
+        new WorkboxPlugin.GenerateSW({

您还可以使用yarn global upgrade generator-jhipster 升级到最新的generator-jhipster 版本，然后使用jhipster upgrade 升级您的项目。有关升级命令的更多信息，请参阅relevant documentation。
