【问题描述】：
我有一个用 Spring Boot、Kotlin、Gradle 制作的简单应用程序。我关注the official tutorial 并尝试遵循所有可能的默认值。
$ git push heroku master
Counting objects: 2, done.
Delta compression using up to 4 threads.
Compressing objects: 100% (2/2), done.

remote: Done: 50.7M

remote: Released v50

奇怪的是，我得到的是“检测到 JVM 通用应用”而不是“检测到 Gradle 应用”。
我无法部署应用程序。当我做heroku logs --tail 时，我得到：

- 使用 Spring Boot 2.0.0.RELEASE
- 使用 Kotlin 1.2.31
-
build.gradle中没有特殊任务 - 没有
Procfile
有没有办法使用默认值（即没有 Procfile，没有特殊的 Gradle 任务）来解决这个问题？如果无法使用默认值，我该怎么办？谢谢
