sbt编译具有不同选项的任务

使用build.sbt中的类似内容，您可以运行sbt compile2：package并从compile config和compile2 config生成一个jar：

val Compile2 = config("compile2") extend Compile

inConfig(Compile2)(Defaults.compileSettings ++ Seq(
    // these options can be set as "in Compile2" outside of inConfig as well
    scalacOptions := SECOND-OPTIONS-LIST,
    // otherwise it will be "src/compile2", you want it to be "src/main"
    sourceDirectory <<= sourceDirectory in Compile,
    sbt.Keys.`package` <<= sbt.Keys.`package` dependsOn (sbt.Keys.`package` in Compile)
))

scalacOptions in Compile := BASIC-OPTIONS-LIST

我想这在代码行方面相对简单，但是如果不非常熟悉sbt的话，就不会那么简单了。
