Gradle 带Jacoco错误的渐变：结束时退出值为非零255

当前环境是一个父项目，在gradle生成文件中映射了多个子项目。 尝试使用Gradle 1.12和Jacoco插件运行它时，在执行JacoTestReport时，在调试中观察到以下错误：

-更新1

从所有项目中删除java和jacoco应用插件可运行测试：

apply plugin: 'java'
apply plugin: 'jacoco'

allprojects {

    jacoco {
        toolVersion = "0.7.0.201403182114"
        //toolVersion = "0.6.2.201302030002"
        //reportsDir = file("$buildDir/reports/jacocoTest.exec")
    }
}

但是，在这种情况下：

：jacocoTestReport跳过了

即使使用当前代码：

jacocoTestReport {
        dependsOn test
        group = "Reporting"
        description = "Jacoco coverage reports after running tests."
        ignoreFailures = true

        doFirst {

            rootProject.subprojects.each {
                println it + " JACOCO----->"
                if (new File("${it.sourceSets.main.output.classesDir}").exists()) {
                    logger.debug("Class files: ${it.sourceSets.main.output.classesDir}")
                    if (classDirectories == null) {
                        classDirectories = fileTree(dir: "${it.sourceSets.main.output.classesDir}", includes: jacocoIncludes, excludes: jacocoExcludes)
                    } else {
                        classDirectories += fileTree(dir: "${it.sourceSets.main.output.classesDir}", includes: jacocoIncludes, excludes: jacocoExcludes)
                    }
                }
            }
        }

        reports {
            xml.enabled true
            csv.enabled false
            html.destination "$buildDir/jacoco/jacocoHtml"
        }
        //classDirectories = fileTree(dir: "$buildDir/classes/main")
        //sourceDirectories = fileTree(dir: "src/main/java")
        executionData = files("$buildDir/jacoco/jacocoTest.exec")
    }

看来Jacoco插件还没有准备好进行开箱即用的递归。。。有解决办法吗

谢谢

堆栈跟踪告诉我们的是Gradle测试JVM退出时代码为255。也许可以尝试隔离这个问题（运行单个子项目，运行单个测试，使用不同的JDK版本运行Gradle，配置不同的JaCoCo版本，等等）。我找不到关于代码255的任何跟踪，它意味着什么？据我所知，它没有标准化的含义。不确定谁负责返回此值。我已更新了jacoco插件配置的问题：当

allprojects{}

正在嵌入

apply plugin:'jacoco'

时，会引发错误。不为所有项目或子项目应用插件会导致0%的覆盖率，因为根项目没有java代码。该问题影响JDK1.6和1.7的两个版本。还测试了$GRADLE_选项的大内存设置。
