Shared SBT module in Intellij Idea without publish-local - intellij-idea

Question

SBT project A depends on B. Both projects have separate VCS repositories and have own lifecycle, including automated building and testing.
Is there a way to work with these projects conveniently in Intellij Idea?
By conveniently, I mostly mean:
CMD-Click points to actual, editable classes between projects, no read-only published jar
No need to run sbt publish-local every time a change is made
Breakpoints work as expected
Looks like all this is not possible if dependency is declared simply as libraryDependencies. However, declaring relationship with relative paths would fail build systems.

Answer 1

Here is what worked for me:
In Project A created a file local-dependencies.sbt (the name not important) with the following contents:
libraryDependencies ~= {l => l.filter(_.name != "my-utils")}
lazy val utils = RootProject(file("../my-utils"))
lazy val root = Project(id = "ProjectA", base = file(".")).dependsOn(utils)
The first line excludes my-utils from libraryDependencies defined in build.sbt which is needed for automated builds.
Now Project A has my-utils as Module dependency, and not Library dependency, which addresses the mentioned issues.
Note, that local-dependencies.sbt is for local env only and should be ignored in VCS, e.g.:
$ cat .hgignore
local-dependencies.sbt

Answer 2

Create IntelliJ Scala sbt Project A.
Then open build.sbt and enter:
name := "A"
version := "0.1"
scalaVersion := "2.12.7"
lazy val b = (project in file("B"))
lazy val root = (project in file("."))
.aggregate(b)
.dependsOn(b)
and save this. When asked "sbt projects need to be imported" in a small dialog box at the right bottom corner, select "Enable Auto-Import".
IntelliJ now creates the subfolder B automatically, and places a target subfolder therein. In subfolder B, create a new build.sbt for B containing:
sourceDirectory in Compile := (baseDirectory( _ / "src" )).value
After save, create new directories B/src/scala.
Open Tool Window for sbt (Menu: View -> Tool Windows -> sbt). Click "Refresh all sbt projects" icon.
Add your library scala Files into B/src/scala.
Now You have a multi module project, consisting out of main module A, depending on library sub-module B.
