Can't fail build in gradle.taskGraph.whenReady(Action)

Expected Behavior

Following code in build.gradle.kts should fail build in the end of configuration phase:

gradle.taskGraph.whenReady {
    throw GradleException("!!!")
}

Current Behavior

Build successful with any type of exception thrown

same code in groovy fails build as expected

gradle.taskGraph.whenReady {
    throw new GradleException("!!!")
}

Context

I'm trying to configure fail fast properties validation for plugin

Your Environment

I'm using gradle 4.10.1 (also tried with .2 version)
It's just a sample Android studio project with provided sample added into root build.gradle.kts

Thanks for the report, @dsvoronin.

Curiously enough the Closure overload fails the build as expected:

gradle.taskGraph.whenReady(closureOf<TaskExecutionGraph> {
    throw GradleException("!!!")
})

Yep, closureOf variant works for me now (somehow failed when i tried)

I think can confirm this works on Gradle 4.9 and now fails on 4.10+. We have code that used to work with this.

For completeness, the Groovy example also fails when cast to use the Action method:

gradle.taskGraph.whenReady({
  throw new GradleException("!!!")
} as Action)

This is the same problem as #7329.

Fixed via #7510. The fix will be in Gradle 5.0.
