ClassNotFoundException正在运行!具有类型安全激活器的应用程序

我有戏了!具有类型安全激活器的应用程序，在原始开发人员的计算机上运行良好。但是当我尝试用命令"sudo ./activator run"在我的计算机上运行应用程序时，我得到以下错误。

    ... 14 common frames omitted

com.samza.adapter.JobFactory类确实存在，并且在正确的目录中。

API的第29 ~ 32行。scala是:

def start: Unit = config getStringList ("task-containers") map
  {
      load(_) run
  }

然后我尝试用命令定义类路径

export CLASSPATH=${CLASSPATH}:/directoryTo/com/samza/adapter

但不幸的是没有成功。

版本:

scala -version
Scala code runner version 2.11.0 -- Copyright 2002-2013, LAMP/EPFL
play -version
play 2.2.3 built with Scala 2.10.3 (running Java 1.7.0_51), http://www.playframework.com
typesafe-activator : 1.2.3

我以前遇到过类似的问题。尝试使用激活器ui运行应用程序。如果您在命令行上运行，请尝试使用activator start而不是activator run运行。
