无法在 heroku 中基于运行 gradle 的 webapp

Question

下面是我试过的。

下面是我的build.gradle

/*

 * This generated file contains a sample Java Library project to get you started.

Procfile

web: build/install/twitter-api9/bin/TwitterApi

当我从 postman 调用我的 api 时，出现以下错误。

错误日志：

我认为 procfile 中有问题，因为我的构建是成功的，但唯一的问题是当我尝试访问我的 application/api 时。该应用程序是一个 spring mvc application，它在 war 部署在本地 tomcat 中运行良好。

编辑：

将我的 Procfile 更改为低于我的 war 所在位置

web: sh build/libs

现在的错误是：

虽然进程以状态 0 退出，但我猜这意味着一切都很好。但应用程序仍然崩溃：

Answer 1

Step by step on how to address this issue:

首先检查 .war 文件的部署位置，具体操作如下：

运行 $ heroku run bash -a twitter-api9 来自 cli.
现在终端已打开，请使用 ls 检查存在的目录。如果不仅仅是 .war 文件的 grep，我相信构建将是其中之一。
一旦你知道 war 位置，将你的 Procfile 更改为以下（对我来说 war 位于 build/libs/ 其他人可能不同):

web: java $JAVA_OPTS -DTG_ENV=prod -jar webapp-runner.jar --port $PORT build/libs/*.war

上面将把请求重定向到这些位置，因为这是一个网络应用程序，你需要一个 webapp-runner.jar /或 jetty-运行ner 或等价物 到运行如果是罐子则不需要 war。

现在应用程序已运行ning 并准备接受请求。但请注意，如果构建成功并且 webapp-runner.jar 位于根目录中，则以上内容有效，否则请提及 jar 的完整路径。
