scala - 如何解决这个异常

Question

调用了此异常但无法解决它...

 Error:scalac: missing or invalid dependency detected while loading class file 'GenericCollection.class'.
 Could not access term play in package <root>,
 because it (or its dependencies) are missing. Check your build definition for
 missing or conflicting dependencies. (Re-run with `-Ylog-classpath` to see the problematic classpath.)
 A full rebuild may help if 'GenericCollection.class' was compiled against an incompatible version of <root>.

Answer 1

错误消息基本上是说 GenericCollection.class 具有对 _root_.play 包的引用，但 play 包不能'找不到。

您必须向提供 play 包的库添加依赖项，该包很可能是 play 框架的一部分。
