使用 Scala 2.8.0b 的 Eclipse 3.5 中出现 Scala 错误，“令牌字符串上的语法错误”

我似乎缺少图书馆，但我不确定。

在这个文件中：

object Test {
    def main(args: Array[String]) {
        for (arg <- args)
            println(arg)
    }
}

我不确定是什么导致了这些错误：

Description Resource    Path    Location    Type
Syntax error on token "object", interface expected  TestSrc.scala   /ScalaDataMiningFunctions/src   line 1  Java Problem
Syntax error on token "String", delete this token   TestSrc.scala   /ScalaDataMiningFunctions/src   line 2  Java Problem
Syntax error on token ":", delete this token    TestSrc.scala   /ScalaDataMiningFunctions/src   line 2  Java Problem
Syntax error on token "<", ( expected   TestSrc.scala   /ScalaDataMiningFunctions/src   line 3  Java Problem

我可能只需要完成这些步骤并在 Netbeans 中执行此操作，但我更愿意找出发生了什么。

在我使用maven创建的lift项目中，我没有这些错误，但是有很多我的jar文件中没有。

一个 jar 文件是 scala-compiler-2.7.3.jar，它位于 lift 项目中，但不在我的 scala 项目中。

我的 scala 项目中唯一的库是 Scala Library version 2.8.0r19106-... 和 JRE System Library [jre1.6.0_07]

I seem to be missing libraries but I am not certain.

In this file:

object Test {
    def main(args: Array[String]) {
        for (arg <- args)
            println(arg)
    }
}

I am not certain what leads to these errors:

Description Resource    Path    Location    Type
Syntax error on token "object", interface expected  TestSrc.scala   /ScalaDataMiningFunctions/src   line 1  Java Problem
Syntax error on token "String", delete this token   TestSrc.scala   /ScalaDataMiningFunctions/src   line 2  Java Problem
Syntax error on token ":", delete this token    TestSrc.scala   /ScalaDataMiningFunctions/src   line 2  Java Problem
Syntax error on token "<", ( expected   TestSrc.scala   /ScalaDataMiningFunctions/src   line 3  Java Problem

I may just need to go through the steps and do this in Netbeans instead, but I would prefer to find out what is going on.

In my lift project, which was created by using maven, I don't have these errors, but there are many jar files there that I don't have in mine.

One jar file is scala-compiler-2.7.3.jar that is in the lift project but not in my scala project.

The only libraries in my scala project are Scala Library version 2.8.0r19106-... and JRE System Library [jre1.6.0_07]
