I am starting to use SBT for scala projects and would like to create a project like:

APP
...Module1
...Module2
    ...Module3

...
build.sbt

would like to know how to build.sbt dependencies so that they are also used in modules.

Thank you for your attention

You can define the modules independently in build.sbt as follows:

lazy val module1 = project
  .settings(
    libraryDependencies ++= deps
  )

lazy val module2 = project
  .settings(
    libraryDependencies ++= deps
  )

lazy val module3 = (project in file("modules/module3"))
  .settings(
    libraryDependencies ++= deps
  )

 val deps = List(
    "dependencia1" %% "exemplo" % "X.Y.Z",
    "dependencia2" %% "exemplo" % "X.Y.Z",
  )

In the example above modules are defined including the list of dependencies. modulo3 explicitly defines the path from which sbt searches its main App.

Another way is to define a dependency relationship between modules:


lazy val module2 = project
  .settings(
    libraryDependencies ++= deps
  )

lazy val module3 = (project in file("modules/module3"))
  .settings()
  .dependsOn(module2)

In this case it is not necessary to reset the value libraryDependencies pro module3
