SBT - 丟失的依賴

Question

好，沒有任何問題，如下圖所示下build.sbt我的合作者運行代碼，而我得到：

[error] /.../GameMap.scala:91: value revalidate is not a member of javax.swing.JFrame 
[error]  frame.revalidate() 
[error]   ^
[error] /.../GameMap.scala:92: value revalidate is not a member of java.awt.Container 
[error]  frame.getContentPane.revalidate() 
[error]      ^

我懷疑，事情是在build.sbt丟失：

scalaVersion := "2.10.4" 

resolvers += "Typesafe Repository" at "http://repo.typesafe.com/typesafe/releases/" 

// scalacOptions ++= Seq("-feature")                                  

libraryDependencies ++= Seq(
    "com.typesafe.akka" %% "akka-actor" % "2.3.8", 
    "com.typesafe.akka" %% "akka-cluster" % "2.3.8", 
    "org.scala-lang" % "scala-swing" % "2.10.4" 
) 

這是什麼？

Answer 1

我的猜測是，你正在運行的Java 6和你的合作者正在運行的Java 7

This is the Container documentation for java 6，不列出從Component繼承revalidate方法。

And here is the java 7 documentation，這並列出revalidate方法從Component

被繼承*同理也可應用於swing
