Java Can'；t启动Play框架应用程序

我创建了play框架应用程序，不幸的是出现了一个问题。当我尝试执行命令

activator run

时，我得到：

也许有人有这样的问题，因为我现在被卡住了。

我终于找到了答案。。。

这个问题导致我的windows 8帐户名…我有一个波兰登录名，所以所有东西都不是用UTF-8编码的，所以这就是我无法构建我的项目的原因

我也有同样的问题。问题是没有正确加载最新的依赖项或更改

试一试

然后再次运行应用程序。希望这能有所帮助。

看起来activator还没有抓住播放依赖项，那么：你的

build.sbt

是什么样子的？那么

project/plugins.sbt

呢？你试过activator clean吗？我试过activator-clean-run-dependecnies-compile，我想我在.ivy2存储库中找到了一些东西……但我不知道是什么。。。这可能与我的环境有关，因为在工作中我没有这种问题……我想在此框架中构建一个业务应用程序，但现在我不确定这是否是一个好的路径：）我的build.sbt文件：'name:=“playW”“”版本：=“1.0-SNAPSHOT”lazy val root=（文件中的项目（“.”）。enablePlugins（PlayJava）scalaversation:=“2.11.1”libraryDependencies++=Seq（javaEbean，缓存）'
