Task 'testFlvDebugUnitTestCoverage' not found in root project 'src'

Hi, I am trying to add Jacoco, code coverage report, into my Android project.
As this is long file, I try to put some related parts.
Although I am able to successfully run following command on my laptop, Bitrise CI complains that:

Task ‘testFlvDebugUnitTestCoverage’ not found in root project ‘src’.

This command is being executed on Bitrise:

$ ./gradlew “–build-file” “build.gradle” “testFlvDebugUnitTestCoverage” “–continue” “–stacktrace”

So, any idea would be appreciated.

Architecture of my app looks like:

-\ passenger-android
---- build.gradle
---- jacoco.gradle
---- setings.gradle
----\ passenger-app
-------- build.gradle
----\ passenger-sdk (this is library for passenger-app)
-------- build.gradle

This is what I have in build.gradle file of passenger-app:

apply plugin: 'com.android.application'
android androidConfiguration
apply plugin: 'io.fabric'
apply plugin: 'com.getkeepsafe.dexcount'
apply plugin: 'com.google.gms.google-services'
apply plugin: 'com.neenbedankt.android-apt'
apply from: "$rootDir/jacoco.gradle"

android {
....
    buildTypes {
        debug {
            testCoverageEnabled = true
    }
....
}

This is what I have in build.gradle file of passenger-sdk:

apply plugin: 'com.android.library'
android androidConfiguration
apply plugin: 'com.neenbedankt.android-apt'
apply from: "$rootDir/jacoco.gradle"

android {
....
}

This is what I have in build.gradle file in root of project:

buildscript {
    repositories {
        jcenter()
        maven { url 'https://maven.fabric.io/public' }
        maven { url 'http://maven.apptimize.com/artifactory/repo' }
        maven { url 'https://zendesk.artifactoryonline.com/zendesk/repo' }
        maven { url "http://www.leanplum.com/leanplum-sdks/" }
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:2.2.0'
        classpath 'io.fabric.tools:gradle:1.22.0'
        classpath 'com.getkeepsafe.dexcount:dexcount-gradle-plugin:0.6.2'
        classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'
        classpath 'com.google.gms:google-services:3.0.0'
    }
}

ext {
    androidConfiguration = {
        sourceSets {
            main {
                manifest.srcFile 'src/main/AndroidManifest.xml'
                java.srcDirs = ['src/main/java']
                resources.srcDirs = ['src/main/resources']
                aidl.srcDirs = ['src/main/java']
                renderscript.srcDirs = ['src/main/java']
                res.srcDirs = ['src/main/res']
                assets.srcDirs = ['src/main/assets']
            }
        }

        testOptions {
            unitTests.all {
                jacoco {
                    includeNoLocationClasses = true
                }
            }
        }
    }
}

And Finally this is my jacoco.gradle file:

import java.util.regex.Pattern

apply plugin: 'jacoco'

/**
 * Jacoco is test coverage tool.
 *
 * Latest version can be found at following link but be careful upgrading — 
 * the latest version may not be compatible yet, resulting in quirks like empty coverage reports.
 * https://bintray.com/bintray/jcenter/org.jacoco:org.jacoco.core
 *
 * You can run the test via following command:
 * $./gradlew testFlvDebugUnitTestCoverage
