当我在lib目录中包含自定义JAR时发生错误 - 播放框架2.0

Question

当我在lib目录中包含一组非托管JAR时，出现此错误。如果我删除lib目录，一切工作正常。如果它在那里，我得到这个错误..任何想法？

据我所知，播放2.0.4包含commons-io:commons-io:2.0.1通过自身由fluentlenium带来的硒。我怀疑你已在lib文件夹中导入了不同版本的commons-io。所以

[my_project] $ dependencies 
... 
| commons-io:commons-io:2.0.1 | org.seleniumhq.selenium:selenium-firefox-driver:2.16.1 | As commons-io.jar | 
... 
[my_project] $ 

无论是从游戏中移除的依赖（如果你不使用fluentlenium），无论是从您的lib目录：

您可以通过播放控制台上使用dependencies检查。

从fluentlenium删除传递依赖，编辑Build.scala你：

val appDependencies = Seq(
    ... 
    ("org.fluentlenium" % "fluentlenium-festassert" % "0.5.6" % "test") .exclude("commons-io", "commons-io") 
    )
