我正在尝试使用 maven 插件将我的应用程序部署到 heroku。但由于部署似乎成功完成，应用程序没有运行。

在我运行heroku:deploy-war 目标后，我的控制台中有这个

[INFO] -----> Packaging application...

表示没有任何重大错误。

当我查看heroku中的日志时，我得到了

2016-09-19T22:41:51.185261+00:00 heroku[api]: Deploy null by userxxx@gmail.com
2016-09-19T22:41:51.185261+00:00 heroku[api]: Release v8 created by userxxx@gmail.com

2016-09-19T22:41:51.990512+00:00 heroku[slug-compiler]: Slug compilation finished

这又不表示任何错误。但是当我导航到我的应用程序应该运行的地址时，在 heroku 中我得到了日志

2016-09-19T22:49:17.825115+00:00 heroku[router]: at=error code=H14 desc="No web processes running" method=GET path="/" host=fast-tundra-46883.herokuapp.com  request_id=4851381b-0fab-49dc-a1a6-d5ebfcad1a97 fwd="79.71.253.17" dyno= connect= service= status=503 bytes=

现在我正在使用 heroiku maven 插件，这是它的配置方式

<plugin>
    <groupId>com.heroku.sdk</groupId>
    <artifactId>heroku-maven-plugin</artifactId>
    <version>1.1.1</version>
    <configuration>
        <appName>fast-tundra-46883</appName>
    </configuration>
</plugin>

我尝试使用<processTypes></processTypes>，因为我没有Procfile。但是在构建过程中我收到了警告

[WARNING] The <processTypes> value will be ignored when deploying a WAR file. Use `heroku:deploy` goal for custom processes.

它不会改变任何东西。

有人可以帮助我并告诉我我做错了什么吗？问候

标签： java maven heroku war

【解决方案1】：

尝试运行：

$ heroku ps:scale web=1

我认为你的 dyno 可能是 alseep。您可以通过运行检查其状态：

$ heroku ps

但是，部署过程中的java.net.SocketException 令人担忧。但看起来确实部署成功了。
