Gradle 6 dependencies with strict version and because keyword - gradle

Question

The problem
I'm currently experimenting with Gradle 6.0 and ran into the problem that I would like to combine the because statement with the syntax for e.g. strict and rejected versions.
My buildscript:
dependencies {
testImplementation(group: 'org.junit.jupiter', name: 'junit-jupiter-api') {
version {
strictly '[5.0, 6.0]'
prefer '5.5.2'
reject '5.5.1' // for testing purpose only
}
}
testRuntimeOnly(group: 'org.junit.jupiter', name: 'junit-jupiter-engine') {
version {
strictly '[5.0, 6.0]'
prefer '5.5.2'
reject '5.5.1' // for testing purpose only
}
}
// Force Gradle to load the JUnit Platform Launcher from the module-path
testRuntimeOnly(group: 'org.junit.platform', name: 'junit-platform-launcher') {
version {
strictly '[1.5, 2.0]'
prefer '1.5.2'
}
}
}
What I've tried so far
I've currently tried to add the because statement below or above the versionstatement and adding curly brackets around them, but none of these things seemed to work out.
The question
Is it possible to add the because statement to the last dependency and if yes, how?
It would be interesting too, to know whether I can combine both testRuntimeOnly into one.

Using the Kotlin DSL, you can easily see exactly what is available to you. So converting your sample to use the Kotlin DSL, we have
dependencies {
testImplementation("org.junit.jupiter", "junit-jupiter-api") {
version {
strictly("[5.0, 6.0]")
prefer("5.5.2")
reject("5.5.1") // for testing purpose only
}
}
testRuntimeOnly("org.junit.jupiter", "junit-jupiter-engine") {
version {
strictly("[5.0, 6.0]")
prefer("5.5.2")
reject("5.5.1") // for testing purpose only
}
}
// Force Gradle to load the JUnit Platform Launcher from the module-path
testRuntimeOnly("org.junit.platform", "junit-platform-launcher") {
version {
strictly("[1.5, 2.0]")
prefer("1.5.2")
}
}
}
Is it possible to add the because statement to the last dependency and if yes, how?
Yes it is. Since I'm using the Kotlin DSL now, I can easily bring up intelli-sense:
You can see here because is available outside the version block, so:
// Force Gradle to load the JUnit Platform Launcher from the module-path
testRuntimeOnly("org.junit.platform", "junit-platform-launcher") {
version {
strictly("[1.5, 2.0]")
prefer("1.5.2")
}
because("my reason here.")
}
