Context

I'm attempting to use Gradle for a Java/Scala multi-project build. Unfortunately, it appears that when having project A depend on project B, the scalaCompile task for project A is not finding the compiled classes from project B.

In my gradle.build file below, the root project depends on macros.

However, the compileScala task complains that it can't find the compiled classes from macros -

Expected Behavior

The compileScala task should be able to find its dependencies' compiled classes.

Current Behavior

The compileScala task is not able to find its dependencies' compiled classes.

Steps to Reproduce (for bugs)

% git clone https://github.com/carymrobbins/intellij-haskforce
% cd intellij-haskforce
% ./gradlew assemble

Your Environment

This happens on Mac and Linux with Gradle 4.0.1.
