gradle - Gradle + TestKit + JaCoco:文件锁定异常

Question

我正在尝试将Gradle TestKit与JaCoCo集成。我正在使用这个插件
https://github.com/koral--/jacoco-gradle-testkit-plugin

这会创建gradle属性(在包含我的插件的测试项目中)，例如:

org.gradle.jvmargs:-javaagent:{someDirsHere}/.gradle/caches/modules-2/files-2.1/org.jacoco/org.jacoco.agent/0.8.1/9aa64427abccf89cfc44a72acaf9d288d80deb8b/org.jacoco.agent-0.8.1-runtime.jar=destfile={someDirsHere}/build/jacoco/test-integration.exec

JaCoCO在主要项目中的设置方式如下:

jacocoTestReport {
    sourceSets sourceSets.main
    executionData = rootProject.files("${buildDir}/jacoco/test.exec", "${buildDir}/jacoco/test-integration.exec") 
}

但是似乎有些东西锁住了test-integration.exec文件。 (如果我将其删除，一切正常

异常是( java.io.IOException:该进程无法访问该文件，因为另一个进程已锁定了文件的一部分):

我有什么想念的吗？
我正在Windows，Java 10.2，Gradle 4.10.1上运行它

查看org.gradle.jvmargs时，它显示为...

destfile={someDirsHere}/build/jacoco/test-integration.exec

这将要求以独占方式访问该文件；锁定它。

不传递参数并使用默认配置应该起作用:

task generateJacocoIntegrationTestKitProperties(type: GenerateJaCoCoTestKitProperties) {
    destinationFile = file('integration.exec')
}

与 jacoco.gradle(最有可能)类似:

jacocoTestReport {
    sourceSets sourceSets.main
    executionData = files()
}

另请参阅此 gist，它看起来很相关，涉及子项目覆盖率测试的汇总:

subprojects.findAll { subproject ->
    subproject.pluginManager.hasPlugin('java') && subproject.pluginManager.hasPlugin('jacoco')
}.each { subproject ->
    executionData += subproject.tasks.jacocoTestReport.executionData
}

executionData = files(executionData.findAll {
    it.exists()
})

对于单个项目，这没有什么意义，但是当拥有子项目时，它确实可行。
