scala：如何在 sbt 中交叉构建库依赖项

Question

我正在使用scala 2.13，我必须使用Gatling load tests，Gatling 不支持Scala-2.13，因为我查看了sbt cross build 和how to cross build library dependency 我有两个 Gatling 依赖项

"io.gatling.highcharts" % "gatling-charts-highcharts" % "3.3.1",
    "io.gatling" % "gatling-test-framework" % "3.3.1"

这些库支持Scala 2.12，因为我正在做这样的事情 build.sbt

lazy val scala212 = "2.12.10"

lazy val scala213 = "2.13.1"

scalaVersion := scala213

lazy val supportedScalaVersions = List(scala213, scala212)

lazy val root = (project in file("."))
  .settings(
    crossScalaVersions := supportedScalaVersions,
  )

libraryDependencies ++= Seq(
  "org.mongodb.scala" %% "mongo-scala-driver" % "2.8.0",
  "com.typesafe.akka" %% "akka-actor" % "2.6.3",
  "com.typesafe.akka" %% "akka-stream" % "2.6.3"
)

libraryDependencies ++= (scalaBinaryVersion.value match {
  case "2.12.10" => Seq(
    "io.gatling.highcharts" % "gatling-charts-highcharts" % "3.3.1",
    "io.gatling" % "gatling-test-framework" % "3.3.1"
  )
  case _ => Seq()
}
  )

Sbt 没有下载 Gatling 依赖项，sbt update 命令没有显示任何错误，看起来case 2.12.10 match 部分甚至没有执行

这样做的正确方法是什么？我想在测试目录中编写加特林模拟

您几乎是对的，但在您的情况下，scalaBinaryVersion 是 2.12。 scalaVersion.value 就是你要找的。​​p>
