当我scala在终端上键入以启动repl时,它会抛出此错误
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)
当我点击enter并输入时println("hello, world"),它再次抛出这个
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并java -version给予
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)
我在运行compile任务时遇到编译错误,因为源引用java.nio.file了仅在Java 7中出现的包中的新类.
我有以下内容build.sbt:
javaHome := Some(file("/opt/jdk/jdk1.7.0"))
fork := true
在sbt:
> show java-home
[info] Some(/opt/jdk/jdk1.7.0)
它在Eclipse中编译并运行良好.如何设置sbt以使用Java 7进行编译？
