以編程方式調用scala解釋器

Question

我試圖使用以下代碼以編程方式調用scala解釋器

val settings = new Settings()
settings.usejavacp.value = true
settings.embeddedDefaults[Probe]
classPath.map(settings.classpath.prepend(_))
classPath.map(settings.bootclasspath.prepend(_))
settings.withErrorFn(err => println(s"error while compiling $err"))
val compile = new Global(settings)
val run = new compile.Run
val sourceFiles = run.compile("Test.scala")

Test.scala看起來像

class Test {
   println ("Hello World!")
}

build.sbt依賴項看起來像

libraryDependencies ++= Seq(
  "org.scala-lang" % "scala-compiler" % "2.11.7",
  "org.scala-lang" % "scala-library" % "2.11.7",
  "org.scala-lang" % "scala-reflect" % "2.11.7"
)

並得到以下錯誤

[error] (run-main-1e) scala.reflect.internal.FatalError: class StringContext does not have a member f

我試過預先添加scala-reflect-2.11.7.jar和scala-library-2.11.7.jar，但似乎什么也沒做

刪除settings.usejavacp.value = true ，這應該有幫助。

PS：不需要Probe ，你可以只使用settings.embeddedDefaults(getClass.getClassLoader)
