Why subprojects does not recognize dependencies? - scala

Question

I've defined two sub projects that looks as follow:
val Http4sVersion = "0.21.0-M4"
val CirceVersion = "0.12.1"
val Specs2Version = "4.7.0"
val LogbackVersion = "1.2.3"
val ScalaTestVersion = "3.0.8"
val TestContainerVersion = "1.11.3"
val KafkaTestContainerVersion = "1.11.3"
val ConfigVersion = "1.3.4"
val SpringVersion = "5.1.8.RELEASE"
val CatsVersion = "2.0.0"
lazy val settings = Seq(
organization := "com.sweetsoft",
name := "connector",
scalaVersion := "2.13.0",
addCompilerPlugin("org.typelevel" %% "kind-projector" % "0.10.3"),
addCompilerPlugin("com.olegpy" %% "better-monadic-for" % "0.3.0"),
scalacOptions ++= Seq(
"-deprecation",
"-encoding", "UTF-8",
"-language:higherKinds",
"-language:postfixOps",
"-feature",
"-Xfatal-warnings",
),
scalacOptions in(Compile, console) ~= {
_.filterNot(Set("-Xlint"))
}
)
lazy val dependencies = Seq(
"org.http4s" %% "http4s-blaze-server" % Http4sVersion,
"org.http4s" %% "http4s-blaze-client" % Http4sVersion,
"org.http4s" %% "http4s-circe" % Http4sVersion,
"org.http4s" %% "http4s-dsl" % Http4sVersion,
"io.circe" %% "circe-generic" % CirceVersion,
"ch.qos.logback" % "logback-classic" % LogbackVersion,
"org.typelevel" %% "cats-core" % CatsVersion,
"com.typesafe" % "config" % ConfigVersion % "test",
"org.scalactic" %% "scalactic" % ScalaTestVersion % "test",
"org.scalatest" %% "scalatest" % ScalaTestVersion % "test",
"org.testcontainers" % "testcontainers" % TestContainerVersion % "test",
"org.testcontainers" % "kafka" % KafkaTestContainerVersion % "test",
"org.springframework" % "spring-core" % SpringVersion % "test",
"org.typelevel" %% "cats-laws" % CatsVersion % "test",
"com.github.alexarchambault" %% "scalacheck-shapeless_1.14" % "1.2.3" % "test",
"org.scalacheck" %% "scalacheck" % "1.14.0" % "test"
)
lazy val global = project
.in(file("."))
.settings(
settings,
libraryDependencies ++= dependencies
)
.aggregate(core, serversupervisor)
lazy val core = (project in file("core"))
.settings(settings)
lazy val serversupervisor = (project in file("serversupervisor"))
.settings(settings)
.dependsOn(core)
As you can see, the two subprojects are core and serversupervisor.
The problem is, that those two subprojects does not recognize dependencies:
I am using Intellj and as you can see, it does not recognize the dependencies.
What am I doing wrong?

Answer 1

Put libraryDependencies ++= dependencies into settings.
global, core and serversupervisor are three different subprojects. They can have different library dependencies. Currently you add them to global but not to core and serversupervisor.
Alternatively you can move libraryDependencies ++= dependencies to Global or
ThisBuild scope rather than specific subproject scope. You can add at top
ThisBuild / libraryDependencies ++= dependencies
or even
Global / libraryDependencies ++= dependencies
