Scala - Java互操作：Scala可以在字节码中发出枚举以供Java使用吗？
[英]Scala - Java interop: can Scala emit enums in bytecode for Java to consume?
问题描述
I have a project that is mixed Java/Scala, it is Java GUI code that makes use of a Scala library. 
我有一个混合Java / Scala的项目，它是使用Scala库的Java GUI代码。 Is there a way to write Scala code such that it will emit Java enums on compile time? 有没有办法编写Scala代码，以便在编译时发出Java枚举？ The approaches I tried so far (sealed case classes, extend Enumeration) seem to generate normal classes which makes working with them from Java much hairier than straight up enums. 到目前为止我尝试过的方法（密封的case类，扩展Enumeration）似乎生成了正常的类，这使得从Java中使用它们比直接枚举更加繁琐。

Why can't you write your enum class in Java ? 为什么不用Java编写enum类？ Mixed-source (ie Java + Scala) projects are perfectly feasible... 混合源（即Java + Scala）项目完全可行......

Scala only supports Java 1.4 features at this point. 此时，Scala仅支持Java 1.4功能。
Java Enums were introduced in Java 1.5. Java Enums是在Java 1.5中引入的。
