Strange syntax error in play framework 2.1.1

I cloned a project from github. It is yesnault / Play20StartApp.

I downloaded the 2.1.1 version and imported it into eclipse.

I can successfully run the app but eclipse keeps telling me that there are some syntax errors in my login.scala.html and wflash.scala.html.

The login.scala.html is as below. 

@(loginForm: Form[Application.Login])

@import helper._
@implicitFieldConstructor = @{ FieldConstructor(twitterBootstrapInput.render) }

<h3>@Messages("signin.signin")</h3>

@form(routes.Application.authenticate(), 'class -> "form-vertical") {

@if(loginForm.hasGlobalErrors) {
    <p class="error">
        <span class="label important">@loginForm.globalError.message</span> </p>}

//value message is not a member of Option[play.api.data.FormError]

<fieldset>
    @inputText(
        loginForm("email"),
        'placeholder -> Messages("email"),
        '_label -> null,
        '_help -> Messages("signin.your.email")
    )
    @inputPassword(
        loginForm("password"),
        '_label -> null,
        'placeholder -> Messages("password"),
        '_help -> Messages("signin.your.password")
    )
</fieldset>

<div class="form-actions">
    <input type="submit" class="btn btn-primary" value="@Messages("signin.signin")">
    <small><a href="@controllers.account.routes.Reset.ask">@Messages("forgot.password")</a></small>
</div>

}

Here is the wflash.scala.html.

@import helper._
@import helper.twitterBootstrap._

not found: value flash

@flash.map {
    case (key, value) => {
        <p class="">
            <span class="badge badge-@key">@value</span>
        </p>
    }
}

After I change @loginForm.globalError.message to @loginForm.globalError.get.message in login.scala.html, the syntax error in it will disappear.

Also, if I change wflash.scala.html to this, there will be no syntax error in it.

@(implicit flash: Flash)
@import helper._
@import helper.twitterBootstrap._

@flash.data.map {
case (key, value) => {
    <p class="">
        <span class="badge badge-@key">@value</span>
    </p>
   }
}

The problem is the app cannot run successfully after I changed them.

The web page in localhost:9000 says "not found: type Flash" and "value get is not a member of play.data.validation.ValidationError".

Who can tell me the solution? Thanks!

After the checkout you shoud cd to your app folder and run play eclipse to let play create valid eclipse project for you.
