我只是在我的Mac上尝试使用play framework 2.0。我一直在使用Play 1.x一段时间没有任何问题。 我已经下载了新的框架，更新了我的PATH以指向新版本的play并创建了一个简单的Java项目（'play new testapp'）
当我调用play run时，我收到以下错误：
log4j:WARN No appenders could be found for logger (akka.event.slf4j.Slf4jEventHandler).
log4j:WARN Please initialize the log4j system properly.
[error] java.lang.NoSuchMethodError: org.slf4j.spi.LocationAwareLogger.log(Lorg/slf4j/Marker;Ljava/lang/String;ILjava/lang/String;[Ljava/lang/Object;Ljava/lang/Throwable;)V
[error] Use 'last' for the full log.
根据上面的错误，我运行'last'命令，下面是从这里产生的堆栈跟踪的摘录：

我启动了一个Ubuntu VM并完成了相同的过程，该应用运行良好。 有什么建议吗？
编辑：我运行了播放类路径以获取应用程序的类路径，这是输出（用...替换了目录的公共部分）：
