SBT构建scala项目中sbt文件中%与%%的区别(sbt scala)

区别：

%% ：用于自动给库包的包名结尾加上Scala的版本号

% ：仅用于分割groupID与artifactID

例如：、

scalaVersion := "2.12.13"

scalacOptions ++= Seq(
  "-deprecation",
  "-feature",
  "-unchecked",
  "-Xfatal-warnings",
  "-language:reflectiveCalls",
)

resolvers ++= Seq(
  Resolver.sonatypeRepo("snapshots"),
  Resolver.sonatypeRepo("releases")
)

// Chisel 3.5
addCompilerPlugin("edu.berkeley.cs" % "chisel3-plugin" % "3.5.0" cross CrossVersion.full)
libraryDependencies += "edu.berkeley.cs" %% "chisel3" % "3.5.0"
libraryDependencies += "edu.berkeley.cs" %% "chiseltest" % "0.5.0"

libraryDependencies这样配置的“chiseltest”版本的完整名称是“edu.berkeley.cs#chiseltest_2.12;0.5.0”，但也限定了scala
