Good evening, I'm studying the Play Framework and I'm hitting on the following error:

I'm not sure what he's complaining about, could anyone from the play help me?

I'm using the Eclipse IDE.

Next, I moved in my code and now the error that occurs at the time I run the COMPILE command is this:

[play-new] $ compile [info] Compiling 9 Scala sources and 5 Java sources to C:\play-new\target\scala- 2.11\classes... [trace] Stack trace suppressed: run last compile:compileIncremental for the full output. [error] (compile:compileIncremental) java.lang.AssertionError: assertion failed: sig=<A:Ljava.lang.Object;>(Lplay.libs.F$Callback2<Lplay.mvc.WebSocket$In<TA;>;L play.mvc.WebSocket$Out<TA;>;>;)Lplay.mvc.WebSocket<TA;>;, index=45, tp=<notype> [error] Total time: 3 s, completed 03/09/2015 23:12:33 [play-new] $ and this is the error that occurs when I try to access LOCALHOSTE: 9000

Execution exception [MatchError: java.lang.AssertionError: assertion failed: sig=<A:Ljava.lang.Object;>(Lplay.libs.F$Callback2<Lplay.mvc.WebSocket$In<TA;>;Lplay.mvc.WebSocket$Out<TA;>;>;)Lplay.mvc.WebSocket<TA;>;, index=45, tp=<notype> (of class java.lang.AssertionError)]

If someone can help me, I thank you, att.
