在Lift Web Framework中,简单构建工具(SBT)的依赖项在LiftProject.scala中指定.该文件包含以下代码:

  override def libraryDependencies = Set(
    "net.liftweb"             %% "lift-webkit"   % liftVersion % "compile->default",
    "net.liftweb"             %% "lift-mapper"   % liftVersion % "compile->default",
    "org.mortbay.jetty"       % "jetty"          % "6.1.22"    % "test->default",
    "junit"                   % "junit"          % "4.5"       % "test->default",
    "org.scala-tools.testing" %% "specs"         % "1.6.6"     % "test->default",
    "org.scala-lang"          % "scala-compiler" % "2.8.1"     % "test->default",
    "org.apache.tomcat"       % "tomcat-juli"    % "7.0.0"     % "test->default",
    "com.h2database"          % "h2"             % "1.2.138"
  ) ++ super.libraryDependencies

%和%%运算符在这里做什么？如果我将此代码粘贴到scala解释器中,则会出错,并且没有为String或RichString定义%或%%.这里发生了什么？
