Can I use java11 with elastic beanstalk and tomcat?
问题
我有一个使用 Scala 2.11 和 Java 11 的 Scala 应用程序，运行在 Tomcat 中。由于某些依赖问题，我不得不从 Java 8 迁移到了 Java 11。
过去，当应用程序还在使用 Java 8 时，我在弹性豆荚（elastic beanstalk）上运行过这个应用程序。然而，似乎没有适用于 Java 11 的弹性豆荚平台。我是否需要找到一种新的部署和运行应用程序的方法，还是有一种简单的方法可以让弹性豆荚运行 Java 11？
我尝试过使用在 https://stackoverflow.com/questions/54088465/java-11-on-aws-beanstalk-for-spring-boot-project 描述的 ebextensions 方法，但它没有起作用，而且似乎是在解决弹性豆荚过时的问题。我觉得是时候放弃弹性豆荚了，但它之前一直运行得很好，所以我不太愿意在没有明确替代方案的情况下放弃它。
根据 https://docs.aws.amazon.com/elasticbeanstalk/latest/platforms/platforms-supported.html#platforms-supported.java 的说明，最新的弹性豆荚平台提供的是带有 Tomcat 8.5 的 Java 8。
根据文档，弹性豆荚的最新 Tomcat 版本是：

I have a scala application that uses scala 2.11 and Java 11 and runs in tomcat . I had to move to Java 11 from Java 8 due to some dependency issues.
In the past I ran this app on elastic beanstalk (back when the app used to run on java 8). However it doesn't look like there's an elastic beanstalk platform for java 11. Do I need to find a new way to deploy and run my app or is there a simple way to get elastic beanstalk to run java11?
Ive tried using the ebextensions approach described at https://stackoverflow.com/questions/54088465/java-11-on-aws-beanstalk-for-spring-boot-project but its not working, and it seems like its working around a problem with elastic beanstalk being stuck in the past. I feel like its time to forget elastic beaanstalk but its worked well up til now so I'm reluctant to do so without a clear alternative.
According to https://docs.aws.amazon.com/elasticbeanstalk/latest/platforms/platforms-supported.html#platforms-supported.java the latest elastic beanstalk platform offered is java 8 with tomcat 8.5
