我的 plugins.sbt 是

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", "libthrift"),
      "com.twitter" %% "finagle-http" % finagleVersion,
      "com.twitter" %% "finagle-core" % finagleVersion
   ),
   scroogeThriftSourceFolder in Compile := {
      val base = baseDirectory.value
      base / "src/main/thrift"
   }
)

src/main/thrift在文件夹中创建 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();
}

并使用编译sbt clean scrooge-gen compile

但我得到编译错误

有趣的是，今天我正在写另一个节俭服务，我发现了这个问题，这是我一年前发布的 :)

幸运的是，解决方案非常简单。

上面代码中使用的插件版本非常旧。

你可以在这里找到这个插件的最新版本

https://bintray.com/twittercsl/sbt-plugins/scooge-sbt-plugin

如果我将 plugins.sbt 文件更新为

addSbtPlugin("com.twitter" % "scrooge-sbt-plugin" % "18.4.0")
