How to apply JaCoCo to build.gradle? - android-studio

Question

I wanted to add JaCoCo to an existing Android Studio Project. In my settings.gradle I edited:
pluginManagement {
gradle.ext.kotlin_version = "1.6.0"
repositories {
google()
mavenCentral()
}
def versionsProp = new Properties()
versionsProp["myapp.version.level"] = "7.1.0-beta05"
def versionsPropFile = file("local.properties")
if (versionsPropFile.canRead()) {
versionsProp.load(new FileInputStream(versionsPropFile))
}
def levelVersion = versionsProp["myapp.version.level"]
plugins {
id("com.android.application") version "$levelVersion"
id("com.android.library") version "$levelVersion"
id("org.jetbrains.dokka") version "1.4.30"
id("org.jetbrains.kotlin.android") version "$gradle.ext.kotlin_version"
id("org.jacoco.core") version "0.8.7"
} }
dependencyResolutionManagement {
repositories {
google()
mavenCentral()
mavenLocal()
} }
rootProject.name = "TestApp"
include ":app"
include ":mylib_1"
include ":mylib_2"
include ":docs"
Especially I added JaCoCo in plugins section. According to this medium article :
Now inside each module’s build.gradle file apply the newly created
jacoco.gradle as such: apply from: "$project.rootDir/jacoco.gradle"
But in my app modules build gradle (I've shortened away stuff commented there) I have follwing structure:
plugins {
id("com.android.application")
id("org.jetbrains.kotlin.android")
}
android {
compileSdkVersion = 31
buildToolsVersion = "31.0.0"
defaultConfig {
applicationId = "org.example.myapp"
// minSdkVersion(21), targetSdkVersion(31) ..
}
// buildTypes, flavorOptions, compose options
// compile options, kotlinOptions, buildFeatures, packagingOptions, lintOptions
}
dependencies {
implementation(fileTree(include: ["*.jar"], dir: "libs"))
implementation("androidx.activity:activity-compose:$compose_activity_version")
implementation("androidx.appcompat:appcompat:$appcompat_version")
testImplementation("junit:junit:4.13.2")
implementation(project(":org_mylib_1"))
implementation(project(":org_mylib_2"))
}
So where or how am I supposed to add the apply from: "$project.rootDir/jacoco.gradle"?
