我遇到Play Framework的一些问题你可以帮我吗？
我尝试了以下内容：
C:\activator new myFirstProject play-scala
C:\cd myFirstProject
C:\myFirstProject\ activator
[myFirstProject] run
效果很好（编译正常，也可以通过浏览器访问）
现在，如果我对java模板进行相同的尝试，那么由于编译错误而无法正常工作......
C:\activator new myFirstProject play-java
C:\cd myFirstProject
C:\myFirstProject\ activator
[myFirstProject] run
日志/错误：
C:\>activator new myFirstProject play-java
Fetching the latest list of templates...
OK, application "myFirstProject" is being created using the "play-java"
template
.
To run "myFirstProject" from the command line, "cd myFirstProject" then:
C:\\myFirstProject/activator run
To run the test for "myFirstProject" from the command line, "cd
myFirstProject"
then:
C:\\myFirstProject/activator test
To run the Activator UI for "myFirstProject" from the command line, "cd
myFirstP
roject" then:
C:\\myFirstProject/activator ui
C:\>cd myFirstProject
C:\myFirstProject>activator

我正在使用Windows 8，激活器1.3.2，我尝试过各种版本的java 1.8和1.7。真正奇怪的是，它在具有相同环境的其他计算机上运行良好（Windows 8，激活器1.3.2和java 1.8）。我怎么能解决这个问题？
非常感谢

打开project/plugins.sbt文件并检查是否有此行：
addSbtPlugin("com.typesafe.play" % "sbt-plugin" % "2.3.8")
