I have an app based as follows:
Spring Framework5.0.4.RELEASEGradle4.7 - multimodule project configured throughJUnit5.1.1
The configuration about Gradle with JUnit is in the build.gradle file located in the root module:
...
subprojects {
    apply plugin: 'java'
    apply plugin: 'eclipse'
    apply plugin: 'org.junit.platform.gradle.plugin'
    sourceCompatibility = '1.8'
    targetCompatibility = '1.8'
    repositories {
        jcenter()
    }
    ext {
      ...
      junitVersion = '5.1.1'
      ...
    }
    dependencies {
       ...
       //Testing
       ...
       testImplementation "org.junit.jupiter:junit-jupiter-api:$junitVersion"
       testCompile "org.junit.jupiter:junit-jupiter-params:$junitVersion";
       testRuntimeOnly "org.junit.jupiter:junit-jupiter-engine:$junitVersion"
       ....
    }
    test {
        useJUnitPlatform()      
    }
}
//This location is mandatory
buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {      
        classpath "org.junit.platform:junit-platform-gradle-plugin:1.1.0"
    }
}
Through Jenkins I execute:
gradle :thymeleaf-02-infrastructure:test --parallel- and with 
Publish JUnit test result reportis configured tothymeleaf-02-infrastructure/build/test-results/junit-platform/*.xml 
From above all work fine, I can see in Jenkins the @Test passed but Gradle does not generate the report directory with the expected html file. 
Even if directly the gradle :thymeleaf-02-infrastructure:test --parallel command is executed in the terminal, all work (tests passe), but Gradle does not generate the report directory with the expected html file.
I already have read these links:
And well I am using
test {
    useJUnitPlatform()      
}
and Gradle is >4.6, 4.7, so what is missing?
