How do you Cross Compile to Scala.JS with Gradle

问题

When adding Scala.JS dependencies in SBT you use %%%. E.g.

libraryDependencies += "be.doeraene" %%% "scalajs-jquery" % "0.9.0"

How is this done in the Gradle Scala plugin?

回答1:

%%% = the scala version + scalajs version. So something like:

val scalaJsDomV = "0.9.1"
libraryDependencies ++= Seq(
   "org.scala-js" %%% "scalajs-dom" % scalaJsDomV
)

would be

compile "org.scala-js:scalajs-dom_sjs0.6_2.12:0.9.1"

Or if you used the ext for multiple used versions it would be something like:

ext {
    versions = [
        js: 'sjs0.6', 
        major: '2.12', // major scala version
    ]
    versions['scala'] = versions.major + '.2'
}
dependencies {
    ...
    compile "org.scala-js:scalajs-dom_${versions.js}_${versions.major}:0.9.1"
}

Note that there is also a plugin that can help with scalajs: https://github.com/gtache/scalajs-gradle
