部署到heroku时未能在Java HelloWorld中收集Maven依赖项

我正在玩Java和heroku。 但几乎没有修改。在本例中，我使用JDK1.7、Jetty 8.1.2.v20120308和Maven dependencies插件2.7（因为似乎无法构建2.4）

所有的都是本地建造的

mvn包

但是当我使用

git推送heroku主机

要在heroku上部署，我收到以下消息：

       [ERROR] Failed to execute goal on project helloart: Could not resolve dep

error: failed to push some refs to 'git@heroku.com:aqueous-castle-5897.git'

我在上读到有关错误的信息，但似乎我必须配置一个settings.xml文件（在heroku上？），如果这是解决方案，我该怎么做

如果不是。。。还有别的想法吗

这是我的pom.xml

谢谢大家!！ 祝你今天愉快

自从pom以来，这听起来像是一个heroku问题，您应该联系heroku支持部门。您可以在打开Heroku support的票证
