sbt是针对Scala2.11构建的吗？

Question

我想用Scala2.11编写一个插件

sbtPlugin := true

scalaVersion := "2.11.0"

当前的sbt版本(0.13.9)构建在Scala2.10.5 https://github.com/sbt/sbt/blob/0.13.9/build.sbt#L27上。

编辑：确实是针对community build中的2.11构建的。

Answer 1

sbt现在使用Scala2.12

目前的sbt版本为1.2.8 (2018年12月30日发布)，自1.0.0以来支持Scala2.12(2017年8月10日发布)

SBT1.0使用Scala2.12进行构建定义和插件。这也需要JDK 8。

https://www.scala-sbt.org/1.x/docs/sbt-1.0-Release-Notes.html#sbt+1.0.0

我们只需跳过Scala2.11并直接进入2.12。

Answer 2

在发布下一个版本SBT0.14或潜在的SBT1.0之前，我们不能破坏所有SBT0.13插件的二进制兼容性，因此Scala2.11.xSBT在此之前不会出现。

更新

解决这一问题的一种方法是使用Fork API。SBT0.13能够使用Scala2.11编译器构建Scala2.11源代码。您可以模仿它的完成方式，并从sbt运行Scala2.10或2.11代码。
