在 heroku 上部署 Java 应用程序

Question

我想我的 Procfile 有问题。我无法在 heroku 上部署我的应用程序，总是在日志中获取此信息:

2016-03-25T12:46:43.601893+00:00 heroku[web.1]: Starting process with command java $JAVA_OPTS -jar target/dependency/webapp-runner.jar --port 45751 target/*.war 2016-03-25T12:46:46.615217+00:00 app[web.1]: Setting JAVA_TOOL_OPTIONS defaults based on dyno size. Custom settings will override them. 2016-03-25T12:46:46.617375+00:00 app[web.1]: Error: Unable to access jarfile target/dependency/webapp-runner.jar 2016-03-25T12:46:47.819108+00:00 heroku[web.1]: Process exited with status 1 2016-03-25T12:46:47.877603+00:00 heroku[web.1]: State changed from starting to crashed

这是我的过程文件: 网络:java $JAVA_OPTS -jar target/dependency/webapp-runner.jar --port $PORT target/*.war

这是我在 gitHub 上的项目

我在你的 pom 中没有看到 webapp-runner.jar。

Heroku 似乎也找不到这种依赖。
