Question

我有一个简单的应用程序在Spring Boot，Kotlin，Gradle中制作。我跟着the official tutorial并试图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.
Writing objects: 100% (2/2), 231 bytes | 231.00 KiB/s, done.
Total 2 (delta 1), reused 0 (delta 0)
remote: Compressing source files... done.
remote: Building source:
remote:
remote: -----> JVM Common app detected
remote: -----> Installing JDK 1.8... done
remote: -----> Discovering process types
remote:        Procfile declares types -> (none)
remote:
remote: -----> Compressing...
remote:        Done: 50.7M
remote: -----> Launching...
remote:        Released v50
remote:        https://---.herokuapp.com/ deployed to Heroku
remote:
remote: Verifying deploy... done.

我发现“检测到JVM Common app”而不是“检测到Gradle应用程序”这很奇怪。

我无法部署该应用。当我heroku logs --tail时，我得到：

2018-04-02T23:02:39.257887+00:00 heroku[web.1]: Starting process with command `java $JAVA_OPTS -Dserver.port=50478 -jar build/libs/scraper-0.0.1-SNAPSHOT.jar`

使用Spring Boot 2.0.0.RELEASE
使用Kotlin 1.2.31
build.gradle
否Procfile

有没有办法使用默认值解决这个问题（即..没有Procfile，没有特殊的Gradle任务）？如果不能使用默认值，我该怎么办？感谢

你确实应该（至少）得到以下内容：

remote: -----> Gradle app detected
remote: -----> Spring Boot detected

这是你第一次推动吗？你手动设置了buildpack吗？也许尝试清除buildpacks（heroku buildpacks：clear）。如果您可以在某个地方发布您的应用，那么检查问题可能会有所帮助。

使用Gradle（Kotlin）应用程序部署Spring Boot - 找不到jar
