为什么sbt试图获得自己的特定版本？

Question

我安装了sbt 0.13.8。

但是，当在文件夹中键入sbt时，sbt试图获取自身的0.13.6版本。我在build.sbt文件中没有发现任何可以解释这种奇怪行为的东西。请告诉我为什么。

以下是build.sbt文件的内容。

enablePlugins(JavaServerAppPackaging)

name := "quiz-management-service"

version := "0.1"

organization := "com.danielasfregola"

scalaVersion := "2.11.7"

resolvers ++= Seq("Typesafe Repository" at    "http://repo.typesafe.com/typesafe/releases/",
              "Spray Repository"    at "http://repo.spray.io")

libraryDependencies ++= {
val akkaVersion       = "2.4.4"
val sprayVersion      = "1.3.3"
Seq(
"com.typesafe.akka" %% "akka-actor"      % akkaVersion,
"io.spray"          %% "spray-can"       % sprayVersion,
"io.spray"          %% "spray-routing"   % sprayVersion,
"io.spray"          %% "spray-json"      % "1.3.3",
"com.typesafe.akka" %% "akka-slf4j"      % akkaVersion,
"ch.qos.logback"    %  "logback-classic" % "1.1.2",
"com.typesafe.akka" %% "akka-testkit"    % akkaVersion  % "test",
"io.spray"          %% "spray-testkit"   % sprayVersion % "test",
"org.specs2"        %% "specs2"          % "2.3.13"     % "test"
)
}

// Assembly settings
mainClass in Global := Some("com.danielasfregola.quiz.management.Main")

jarName in assembly := "quiz-management-server.jar"

Answer 1

我想通了。可以使用语法build.properties在项目文件夹下使用sbt.version=0.13.x强制使用sbt版本。
