我想用scala 2.11编写一个插件

sbtPlugin := true

scalaVersion := "2.11.0"

当前的sbt版本(0.13.9)是基于scala 2.10.5建立的 https://github.com/sbt/sbt/blob/0.13.9/build.sbt#L27

编辑: 在社区构建中构建 2.11 .

[sbt] The following subprojects will be built in project sbt: launcher-interface, test-agent, control, io, datatype-generator, process, scripted-framework, interface, launcher, precompiled-2_8_2, relation, classpath, api, precompiled-2_9_2, logging, compile, run, classfile, scripted-sbt, testing, incremental-compiler, persist, compiler-integration, precompiled-2_9_3, …

我是Spark和Scala的新手.我用SBT创建了一个IntelliJ Scala项目,并为build.sbt添加了几行.

name := "test-one"

version := "1.0"

scalaVersion := "2.11.2"

libraryDependencies += "org.apache.spark" % "spark-core_2.10" % "1.1.0"

我的Scala版本是2.10.4,但2.11.2也会出现这个问题
