Question

我一直在尝试将我的Java应用程序部署到Heroku 2天。我做的事与人们在他们的教程中做的一样。但有些事情是错的。如何解决？

这是heroku应用程序日志

我的pom.xml中的

插件

                </execution>
            </executions>
        </plugin>

和Procfile

web: java $JAVA_OPTS -cp target/dependency/jetty-runner.jar --port $PORT target/*.war

Answer 1

到目前为止，我已经在免费帐户中部署了node.js应用程序而没有插件。而我必须做的是采用heroku分配的端口而不是静态的端口，您似乎指定了

--port 37825

也许这就是问题所在？该错误似乎与端口有关。尝试谷歌“动态端口heroku java”

Answer 2

您的Procfile应该是：

web: java $JAVA_OPTS -jar target/dependency/jetty-runner.jar --port $PORT target/*.war

请注意-jar而不是-cp

无法将Java Web应用程序部署到Heroku
