Trigger SBT assembly from other subproject

I have a root project containing 3 subprojects plus sbt config files and nothing else. 2 main subprojects are called server and backend, the other is called common and is dependency of both main projects. server is PlayFramework project. backed project is configured to generate assembly jar into resources directory of server.

The jar is generated correctly and server is able to see it, but I don't know how to run assembly task from backend when server is compiled(i.e. I want the server to depend on assembly of backend.jar)

/* [...] */

lazy val commonSettings = Seq(
  version := "0.1",
  organization := "org.example",
  scalaVersion := "2.11.7"
)

lazy val server = (project in file("server")).enablePlugins(PlayJava).settings(commonSettings: _*).settings(
  name := """example""",
  libraryDependencies ++= Seq(
    /* [...] */
  ),
  /* [...] */
  unmanagedResourceDirectories in Compile += { baseDirectory.value / "resources" }
).dependsOn(common)


lazy val backend = (project in file("backend")).settings(commonSettings: _*).settings(
  assemblyJarName in assembly := "backend.jar",
  assemblyOutputPath in assembly := server.base / "resources/backend.jar",
  libraryDependencies := Seq(

  )
).dependsOn(common)

lazy val common = (project in file("common")).settings(commonSettings: _*)

onLoad in Global := (Command.process("project server", _: State)) compose (onLoad in Global).value

Thanks to comment by @pfn I got it working. One thing I needed to do was to insert this line in server subproject settings and change server to Compile, so it is now:

(compile in Compile) <<= (compile in Compile) dependsOn (assembly in backend)
