IntelliJ's "Rebuild Project" fails for a Gradle project when multi-module buildSrc

Hi,

I am running IntelliJ 2017.3.4 and have configured it to delegate IDE build/run actions to Gradle. IntelliJ is also configured to run tests using the Gradle Test Runner.

I have created a simple Gradle project that imports into IntelliJ perfectly and also builds OK from the command line. However, if I select "Build/Rebuild Project" from IntelliJ then IntelliJ fails at the "Calculate task graph" stage with the message:

"Project 'plugin' not found in root project 'example-project'."

having tried to execute this script from the /tmp directory:

//-- Additional script
projectsEvaluated {
 rootProject.project(':').tasks.withType(AbstractCompile) {
 outputs.upToDateWhen { false }
 }
}

projectsEvaluated {
 rootProject.project(':example:').tasks.withType(AbstractCompile) {
 outputs.upToDateWhen { false }
 }
}

projectsEvaluated {
 rootProject.project(':plugin:').tasks.withType(AbstractCompile) {
 outputs.upToDateWhen { false }
 }
}

allprojects {
 tasks.withType(JavaCompile) {
 options.compilerArgs += ["-Xlint:deprecation"]
 }}

//

The problem appears to be that it is mistaking the "plugin" sub-project within buildSrc for a module within the main project. I have not had any success with the 'idea' Gradle plugin. I have uploaded my example project to https://uploads.services.jetbrains.com/ with filename "breaker-360000100650.tar.xz". (It's only 896b long.)

Can anyone help please?

Thank you,
