生成案例 class with Binding.scala Vars using Scala.meta throws an exception

Question

我有一个 scala.js 项目。 Scala.Meta 和 Binding.scala.

我有一个奇怪的行为

我想从一个案例 class:

创建一个案例 class

case class SimpleCaseClass(i: Int, s: String, list: Seq[String])

应该生成到：

SimpleCaseClassFormData(Var[Int], Var[String], Vars[String])

我一收到 Vars，就收到以下错误：

A method defined in a JavaScript raw type of a Scala.js library has been called. This is most likely because you tried to run Scala.js binaries on the JVM. Make sure you are using the JVM version of the libraries.
java.lang.Error: A method defined in a JavaScript raw type of a Scala.js library has been called. This is most likely because you tried to run Scala.js binaries on the JVM. Make sure you are using the JVM version of the libraries.

没有（例如SimpleCaseClassFormData(Var[Int], Var[String])）它有效。

宏注释已弃用（参见 https://github.com/scalameta/scalameta/issues/1182）

您可以创建一个基于 Scala Meta 的 sbt 插件。请参阅 https://github.com/ThoughtWorksInc/sbt-example/ 作为实施此类插件的示例。

为避免版本不兼容，您应该使用 sbt 的 built-in Scala Meta，它是 1.7.0 版。
