Intellij 15.0.3支持gradle和scala吗？

我正在使用Intellij IDEA 15.0.3 BUILD＃IC-143.1821

• 斯卡拉插件2.1.0
• Gradle插件143.1821.5

当我加载一个gradle项目，我发现我不能运行scala应用程序与此错误：

很明显，scala库不在类路径中。

• 在“打开模块设置”中，我可以在“项目设置 – >模块 – >依赖关系”中找到scala库。
• 在“Project settings – > Libraries”中，有2.10.4的scala-sdk。
• 没有在“项目设置 – >方面”

IDEA似乎不支持Gradle和Scala。 如果我创建一个新的项目，选择Gradle，我只能使用框架Java，Groovy和Kotlin; 同时选择Scala，只有Scala，SBT和Activator。

我是Intellij新手。 我犯了一些错误吗？
