scala – 无法编译scrooge thrift插件生成的源代码

addSbtPlugin("com.twitter" % "scrooge-sbt-plugin" % "4.8.0")

我的build.sbt是

val finagleVersion = "6.45.0"

lazy val myProject = Project("FinagleTest",file("."))
   .settings(
   name := "FinagleTest",version := "1.0",scalaVersion := "2.12.2",libraryDependencies ++= Seq(
      "org.apache.thrift" % "libthrift" % "0.9.2","com.twitter" %% "scrooge-core" % "4.18.0" exclude("com.twitter","libthrift"),"com.twitter" %% "finagle-thrift" % finagleVersion exclude("com.twitter","com.twitter" %% "finagle-http" % finagleVersion,"com.twitter" %% "finagle-core" % finagleVersion
   ),scroogeThriftSourceFolder in Compile := {
      val base = baseDirectory.value
      base / "src/main/thrift"
   }
)

在src / main / thrift文件夹中创建了temprature_service.thrift文件

namespace * com.foo.temprature.thrift
struct TempratureDatum {
    1: i32 celcius,2: i64 timestamp
}

service TempratureService {
    void add(1: TempratureDatum datum);
    double mean();
}

并使用sbt clean scrooge-gen编译编译

但我得到编译错误
