Junit 5 and Gradle 4.6 check task shows "Test events were not received"

IntelliJ IDEA 2017.3.5

Gradle 4.6

Trying to migrate to junit5, but having an issue where the gradle check task doesn't display the tests in the run window, instead it says "Test events were not received".

When I run the same thing with junit4, tests are displayed:

build.gradle

group 'com.tryingtomigrate'
version '1.0-SNAPSHOT'

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'org.junit.platform:junit-platform-gradle-plugin:1.1.0'
    }
}

apply plugin: 'java'
apply plugin: 'org.junit.platform.gradle.plugin'

sourceCompatibility = 1.8

repositories {
    mavenCentral()
}

dependencies {
    testCompile  'org.junit.jupiter:junit-jupiter-api:5.1.0'
    testCompile  'org.junit.jupiter:junit-jupiter-engine:5.1.0'
}

package com.tryingtomigrate;


import org.junit.jupiter.api.Test;

import static org.junit.jupiter.api.Assertions.assertTrue;

public class myTest {
    @Test
    public void myTests() {
        assertTrue(true);
    }
}
