SBT啓動失敗

Question

我想建立一個簡單的SBT項目，但它與一個惱人的錯誤而失敗：

λ sbt 
Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=256m; support was removed in 8.0 
[info] Loading global plugins from C:\Users\name.surname\.sbt\0.13\plugins 
[info] Loading project definition from C:\work\ScalaKafkaScripts\project 
[error] [C:\work\ScalaKafkaScripts\build.sbt]:9: illegal start of simple expression 
[error] [C:\work\ScalaKafkaScripts\build.sbt]:12: ')' expected but eof found. 
Project loading failed: (r)etry, (q)uit, (l)ast, or (i)gnore? 

這裏是build.sbt全部內容：

import Dependencies._ 

lazy val root = 
    (project in file(".")) 
     .settings(
     inThisBuild(List(
      organization := "yo.jevramonitor", 
      scalaVersion := "2.12.1", 
     )), 
     name := "ScalaKafkaScripts", 
     libraryDependencies ++= allDeps 
    ) 

這裏是Dependencies文件內容：

import sbt._ 

object Dependencies { 
    lazy val kafka = "org.apache.kafka" %% "kafka_2.11" % "0.10.1.0" 
    lazy val allDeps = Seq(kafka) 
} 

這裏是目錄結構：

Answer 1

在scalaVersion := "2.12.1",卸下後面的逗號。像斯卡拉本身尾隨逗號沒有在SBT語法，即允許，你可以有

Seq("foo", "bar") 

但不

Seq("foo", "bar",)
