Sencha Nashorn 引擎计划从未来的 JDK 版本中删除

Question

知道如何修复/删除此警告吗？

我只是在做一个 sencha app build 或 npm run clean && cross-env webpack --env.profile=modern --env.environment=production --env.treeshake=yes

操作系统是 Ubuntu 18 LTS。

我想跟进这件事，因为前几天我顿悟了。对于我的家庭项目，当我开始使用开放工具/npm 方法时，我意识到我不必安装 Java。在工作中，我们有一个项目是在开放工具方法之前创建的，所以我们必须下载并安装 Sencha Cmd exe，它需要 Java。

长话短说，我从工作机器上卸载了 Java，删除了 node_modules 目录和 package-lock.json 文件，然后重新运行了 npm install。当我这样做时，我得到了一个全新的package-lock.json，并且应用程序在没有 Java 的情况下构建/运行。我认为管道中有一些聪明的地方可以检查你是否安装了 Java，如果你安装了，你会得到完全不同的依赖关系。
