A simple way to have programs written in different programming languages communicate with each other is using REST. 使使用不同编程语言编写的程序相互通信的一种简单方法是使用REST。 Also if asynchronous communication is preferred, you may want to exchange messages via a message broker (eg RabbitMQ). 同样，如果首选异步通信，则可能要通过消息代理（例如RabbitMQ）交换消息。

I would recommend deploying two different apps (one written in Ruby and the other written in Java) and have the ruby app expose a REST endpoint that can be triggered by your java app. 我建议您部署两个不同的应用程序（一个用Ruby编写，另一个用Java编写），并让ruby应用程序公开一个可由Java应用程序触发的REST端点。 You could secure this endpoint using some authentication mechanism (eg HTTP Basic). 您可以使用某种身份验证机制（例如HTTP Basic）来保护此端点。

The possibility of running 2 different buildpacks with a single application does, to the best of my knowlege, not exist. 据我所知，使用单个应用程序运行2个不同的buildpack的可能性确实不存在。 Also this does not seem to be a clean approach in my eyes. 在我看来，这似乎也不是一种干净的方法。
