JUnit 5 under Gradle with multiple source sets

Question

I've got a project I'm putting together that I want to use JUnit 5 for. I've got this working fine for Unit Tests already.

I do however have multiple test source sets - I've got an additional one for Acceptance Tests. I'm struggling to work out how to get JUnit 5 to run the Unit Tests - defined in src/test - in one task and the Acceptance Tests - defined in the "acceptanceTest" sourceSet and located in "src/acceptance" - in another task.

I have previously got this working with JUnit 4 and Cucumber, but the JUnit 5 plugin doesn't seem to want to work like this.

build.gradle:

buildscript {
  ext {
    jackson_version = "2.9.0.pr4"
    // IntelliJ needs M4
    junitJupiter_version = "5.0.0-M4"
    junitPlatform_version = "1.0.0-M4"
    kotlin_version = "1.1.3-2"
    slf4j_version = "1.7.25"
    spring_version = "4.3.10.RELEASE"
    springBoot_version = "1.5.4.RELEASE"
    springBootAdmin_version = "1.5.2"

    runAcceptance = System.properties['noAcceptance'] == null
  }

Since Gradle 4.6 the gradle Java plugin has JUnit 5 support

So once you have configured the test source sets, the setup is as simple as follows - for my test and intTest test tasks I just need to configure this to use JUnit5:

apply plugin: 'java'

test {
    useJUnitPlatform()
}

intTest {
    useJUnitPlatform()
}

dependencies {
    testCompile("org.junit.jupiter:junit-jupiter-api:5.1.0")
    testRuntime("org.junit.jupiter:junit-jupiter-engine:5.1.0")

}
