Scala repl引发错误 [英] Scala repl throws error

问题描述

当我在终端上键入scala来启动repl时，它会引发此错误

When I type scala on the terminal to start the repl, it throws this error

scala> [init] error: error while loading AnnotatedElement, 
class file '/usr/lib/jvm/java-8-oracle/jre/lib/rt.jar
(java/lang/reflect/AnnotatedElement.class)' 
is broken (bad constant pool tag 15 at byte 2713)

当我按下 enter 并键入println("hello, world")时，它将再次抛出

When I hit enter and type println("hello, world"), it again throws this

error: error while loading CharSequence, 
class file '/usr/lib/jvm/java-8-oracle/jre/lib/rt.jar
(java/lang/CharSequence.class)' is broken
(bad constant pool tag 15 at byte 1501)

我正在使用Ubuntu 14.04和java -version给出

java version "1.8.0_05"
Java(TM) SE Runtime Environment (build 1.8.0_05-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.5-b02, mixed mode)

推荐答案

要么更新到新的Scala版本(2.10.3+)，要么将Java降级为Java 6/7.正如您在输出中看到的那样，2.9.2在引入Java 8之前很早(Copyright 2002-2011, LAMP/EPFL)，因此它们不能很好地协同工作.

Either update to a newer scala version (2.10.3+) or downgrade java to java 6/7. As you have seen in the output, 2.9.2 was here long before java 8 was introduced (Copyright 2002-2011, LAMP/EPFL), so they don't work well together.

这个重复的问题包含有关ubuntu的Java降级的确切说明.
