使用gradle执行时，不会创建serenity xml文件

Question

任何人都可以告诉我为什么在使用gradle执行脚本时没有生成serenity xml文件。

html文件，SERENITY-JUNIT.xml，index.html正在创建，但未创建.xml文件。

的build.gradle

repositories {    
jcenter()
mavenCentral()
}

buildscript {
repositories {
mavenLocal()
jcenter {
url "http://jcenter.bintray.com/"
}
}

dependencies {
classpath("net.serenity-bdd:serenity-gradle-plugin:1.2.2-rc.5")
}
}

apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'idea'
apply plugin: 'net.serenity-bdd.aggregator' 

jar {
baseName = 'gs-gradle'
version =  '0.0.1'
}

dependencies {
    compile 'org.seleniumhq.selenium:selenium-java:3.0.1'
    compile 'net.serenity-bdd:serenity-junit:1.2.2-rc.5'
    compile 'net.serenity-bdd:serenity-core:1.2.2-rc.5'
    compile 'net.serenity-bdd:serenity-jbehave:1.19.0'
    compile 'net.serenity-bdd:serenity-gradle-plugin:1.2.2-rc.5'
    compile 'org.slf4j:slf4j-simple:1.7.22'
    compile 'log4j:log4j:1.2.17'
    testCompile 'junit:junit:4.12'
    compile 'com.itextpdf:itextpdf:5.5.10'
    compile 'com.itextpdf.tool:xmlworker:5.5.10'
    compile 'commons-io:commons-io:2.5'
    compile 'org.assertj:assertj-core:3.6.1'
    compile 'com.googlecode.lambdaj:lambdaj:2.3.3'
    compile 'org.scream3r:jssc:2.8.0'
    compile 'org.apache.commons:commons-exec:1.3'
    compile 'org.apache.commons:commons-lang3:3.5'
    compile 'com.jcraft:jsch:0.1.54'
    compile 'com.googlecode.json-simple:json-simple:1.1.1'
 }

task testAudioAlarm(type: Test)
{ 
description 'Runs the Alarm recording BDD tests.' 
scanForTestClasses = false 
maxParallelForks = 1 
forkEvery = 1 
include '**/AMSTestSuite' 
}

gradle.startParameter.continueOnFailure = true

命令我用来执行脚本“gradle clean test aggregate”
