sbt add java project

Question

Working on some scala software in IDEA IntelliJ. (It also features Android if it is essential). Suppose I have two projects:

P1, written in scala, uses sbt as the build

Answer 1

When I try to compile that, sbt tells me that it cannot find definitions of that dependency.

Two possible solutions I see: add those dependencies in your build.sbt project or as suggested build the gradle project separately, publish it to your local repository (or local folder) and reference it from sbt project.
