以下是我的尝试。

以下是我的 build.gradle

当我从邮递员那里给我的api打电话时，我得到了以下错误。

我认为procfile中存在错误，因为我的构建成功但唯一的问题就是当我尝试访问我的应用程序/ api时。该应用程序是spring mvc application，在本地tomcat中部署了war，运行良好。

编辑：

将 Procfile 更改为我的战争所在的位置

web: sh build/libs

现在错误是：

虽然进程以状态0退出，我猜这意味着一切都很好。但仍然应用程序崩溃：

Answer 1

逐步说明如何解决此问题：

首先检查.war文件的部署位置，可以按如下方式进行：

从cli。

$ heroku run bash -a twitter-api9

现在终端已打开，请检查当前目录的ls。我相信如果不仅仅是grep for .war文件，build将是其中之一。
一旦你知道了战争地点，你的 Procfile 就会改为下面（对我而言，战争存在于build / libs /中可能与其他人不同）：

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

以上内容会将请求重定向到这些位置，因为这是一个Web应用程序，您需要 webapp-runner.jar /或jetty-runner或等效才能运行战争如果它是一个罐子需要。

现在应用程序正在运行并准备接收请求。但请注意，如果构建成功并且webapp-runner.jar位于root目录中，则上述方法有效，否则请提及jar的完整路径。

无法在heroku中运行基于gradle的webapp
