How to add jacocoagent.jar to Android build.gradle - Failed resolution of: Lorg/jacoco/agent/rt/internal_3570298/Offline;

Question

I have following setup

AGP 7.x+
Kotlin 1.5.x+
JaCoCo 0.8.7+
Java 11 set as the JDK
Java 1.8 set as jvmTarget and compileOptions

but when trying to run the AndroidTest and generate jacoco report, it fails with

java.lang.NoClassDefFoundError: Failed resolution of: Lorg/jacoco/agent/rt/internal_3570298/Offline;

After doing my research it seems I need to add jacocoagent.jar to classpath, but how?

Tried adding testImplementation 'org.jacoco:org.jacoco.agent:0.8.7' and also downloading jar file from search.maven.org/artifact/org.jacoco/org.jacoco.agent/0.8.7/jar and adding jacoco-agent.properties file referencing the jar but no success :/ what am I missing...

(things I've looked into:

Removing Jacoco library dependency while exporting project as jar

how to prevent jacoco instrumenting production code?

any luck with this, still facing this issue in AS Android Studio Chipmunk | 2021.2.1 Patch 1 — williamj949, Jun 08 '22 at 12:10

You need to use the correct classifier in the artifact coordinates in order to directly reference the jacocoagent.jar:

 [group: 'org.jacoco', name: 'org.jacoco.agent', classifier: 'runtime',
 version: "$JACOCO_VERSION"]

As in:

configurations {
    ...
    jacocoAgent
    ... }

dependencies {
    ...
    jacocoAgent ([group: 'org.jacoco', name: 'org.jacoco.agent', classifier: 'runtime', version: "..."],)
    ... }
