java - 使用 Heroku (npm java) 部署失败

Question

我正在尝试通过 Heroku 部署我的应用程序，它在本地主机上运行良好。尽管我在本地主机上安装 java 模块时遇到了一些麻烦，但我终于做到了，感谢这篇文章:https://github.com/nodejs/node/issues/10289 .

现在，我在 Heroku 上部署应用程序时显然遇到了同样的错误，但现在我无法修复它。我什至设置了 Java Buildpack，以防万一，但它没有帮助。

我希望有人能帮助我!

这是我的 package.json:

Answer 1

看来您的 node-gyp 需要正确构建 java。 Heroku 架构的问题在于它只提供您指定/需要的内容。现在我认为 Heroku 不明白它需要一个 JVM 来运行你的应用程序。所以你应该提供一个buildpack。简单地说，构建包是一组规则，告诉 Heroku 要设置、安装和构建什么。有一个名为 heroku/jvm 的 JVM 构建包。因此，您需要做的是通过仪表板或 CLI 通过 heroku buildpacks:add heroku/jvm 将其添加到您的应用程序。

还有一件事要做。由于您的应用程序本身在构建时需要 javac，因此我们应该提取 java/jvm 的构建顺序。所以在这种情况下，您可能应该执行 heroku buildpacks:add --index 1 heroku/jvm。这会将 JVM buildpack 放在位置 1 并将所有其他 buildpack 推下顺序。

现在，当应用程序开始构建时，它首先设置 JVM(从而为您的实例启用 javac)，然后运行 ​​NodeJS 构建。此构建现在将从当前实例中获取 javac 并进行相应构建。
