see similar error message, like I can see in my IDEA:

or similar to what I can see in build/reports HTML:

project gradle build configuration

subprojects {
  apply plugin: 'groovy'
  sourceCompatibility = '1.8'
  repositories.jcenter()

  dependencies {
    implementation 'org.codehaus.groovy:groovy-all:2.5.10'
    testImplementation platform('org.spockframework:spock-bom:2.0-M1-groovy-2.5')
    testImplementation 'org.spockframework:spock-core'
    testImplementation 'org.spockframework:spock-junit4'
  }

  test {
    useJUnitPlatform()
    testLogging {
      showCauses = true
      showExceptions = true
      showStackTraces = true
      showStandardStreams = true
      events 'passed', 'skipped', 'failed'
    }
  }
}

PS: using gradle init task with additional guides and configuration examples:

I'm hitting this same problem. I did discover that running Gradle with "--info" level output causes the Spock error details to appear, along with a ton of other info-level status messages. It would be preferable if the assertion details would be shown even without the "--info" flag.
