Gradle中的并行任务未完成（connectedAndroidTest）

我在gradle.properties中有org.gradle.parallel=true。我正在运行一个后端Google云模块，同时运行一个connectedAndroidTest，它执行一些浓缩咖啡测试。测试成功，任务以绿色显示正常（请参见图），但连接的测试任务从未实际完成自身或打印行，并且不会移动到队列中的下一个任务

如果我自己运行任务，它将结束并打印行

我的root build.gradle文件：

buildscript {
    repositories {
        jcenter()
        google()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.0'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
        google()
    }
}

// Task to set up GCE, runs paid flavor test and shuts down the server.
task configureTest {
    dependsOn 'startBackend', 'runInstrumentedTest', 'stopBackend'
    doLast {
        println 'Tests carried out and local server shut down'
    }
}

task startBackend {
    dependsOn ':backend:appengineRun'
}

// Run InstrumentedTest only in paid flavor as there is no interstitial ad.
task runInstrumentedTest {
    mustRunAfter 'startBackend'
    dependsOn ':app:connectedPaidDebugAndroidTest'
    doLast {
        println 'The test finished.'
    }
}

task stopBackend 
    mustRunAfter 'runInstrumentedTest'
    dependsOn ':backend:appengineStop'
}

为了避免任何阻塞，请尝试以守护程序模式启动后端，并查看它是否有助于您正确完成测试。要做到这一点，请在后端的build.gradle文件中添加以下内容：

buildscript {
    repositories {
        jcenter()
        google()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.0'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
        google()
    }
}

// Task to set up GCE, runs paid flavor test and shuts down the server.
task configureTest {
    dependsOn 'startBackend', 'runInstrumentedTest', 'stopBackend'
    doLast {
        println 'Tests carried out and local server shut down'
    }
}

task startBackend {
    dependsOn ':backend:appengineRun'
}

// Run InstrumentedTest only in paid flavor as there is no interstitial ad.
task runInstrumentedTest {
    mustRunAfter 'startBackend'
    dependsOn ':app:connectedPaidDebugAndroidTest'
    doLast {
        println 'The test finished.'
    }
}

task stopBackend 
    mustRunAfter 'runInstrumentedTest'
    dependsOn ':backend:appengineStop'
}
