SBT編譯錯誤：在StringOps

Question

沒有augmentString方法我在Fedora 21：

• 斯卡拉2.10.3
• 的Java 1.8.0
• SBT 0.13.1

使用yum安裝了Scala和java。 Sbt手動安裝並且在~/.bashrc文件末尾添加行export PATH=/home/igor/Documents/Projects/Scala/Assignments/sbt/bin:$PATH以使sbt在終端中可用。然後，當我的CD到/home/igor/Documents/Projects/Scala/Assignments/example和運行sbt -h，通常顯示的幫助信息，但如果開始SBT：

[igor@prague example]$ sbt 
Loading /home/igor/Documents/Projects/Scala/Assignments/sbt/bin/sbt-launch-lib.bash 
OpenJDK Server VM warning: ignoring option MaxPermSize=256m; support was removed in 8.0

    at xsbt.boot.Boot.main(Boot.scala) 
Error during sbt execution: java.lang.NoSuchMethodError: scala.Predef$.augmentString(Ljava/lang/String;)Lscala/collection/immutable/StringOps; 

如果我下載scala 2.10.4和yum remove scala和新斯卡拉添加到路徑就像我與SBT手工做的，同樣的錯誤依然存在。

是否有可能使sbt工作？我需要運行sbt submit命令才能將作業提交給Coursera。

不知道，但它可能是一個問題與Java 8 從類型安全blog斯卡拉2.11

The Scala 2.11 series targets Java 6, with (evolving) experimental support for Java 8. In 2.11, Java 8 support is mostly limited to reading Java 8 bytecode and parsing Java 8 source. We will be expanding Scala's (experimental) Java 8 support and interop throughout the 2.11 series.

如果2.11版本只有實驗性支持，那麼2.10也將不會有一個適當的支持Java 8.你可以做java 7的課程。這是一個真棒課程順便說一句:)
