IssueTracker

Attached is a zip file with an example project I created which will make it easy to reproduce the issue.

1. Unzip and check the project out in android studio.
2. Run gradle clean app:jacocoTestReportDebug.
3. Open $projectDir/build/reports/jacoco/jacocoTestReportDebug/html/index.html in a web browser to see the expected result.
4. Now go to $projectDir/app/build.gradle and uncomment line 22 enableTransformForLocalTests = true.
5. Repeat steps 2 and 3 to see the incorrect coverage.

In the case of this project, I wrote a simple test which does not use the dependency I created, but in more complex projects this enableTransformForLocalTests needs to be set to true.

I hope this will give more insight into the problem, regards, Michael

Hello, We faced similar(same?) issue. I see bunch of warnings in jacoco output during coverage processing: [WARN] Execution data for class xxx/xxx/xxx/xxx does not match. I found workaround for this problem, but it looks very fragile. You can add build/intermediates/asm_instrumented_project_classes/<Product>Debug/ folder to classDirectories in jacoco report task. This will fix problem with instrumented class files.

abstract class MyActivity : AppCompatActivity() {
  @AndroidEntryPoint
  class EntryPoint : MyActivity()
}

abstract class MyFragment : Fragment() {
  @AndroidEntryPoint
  class EntryPoint : Fragment()
}

I am lifting the code by adding nested class and inheriting the one that implements most of the code. This way I can keep the code in one location. Still, it is not convenient as I need to suffix in all AndroidManifest the activities with "$EntryPoint". For example, com.my.project.MyActivity$EntryPoint.

Since AGP 7.2.0 our projects are impacted by this issue, too.

Configuration:

• AS: Chipmunk Patch 1
• AGP: 7.2.1
• Gradle: 7.3.3
• Java: OpenJDK 11
• Kotlin: 1.7.0
• Jacoco: 0.8.7
• Hilt: 2.42

I created a minimal example of the project setup: https://github.com/sarn0ld/JacocoHiltAGP720Problem (See README.md for workarounds...)

I'm seeing the same issue, but with newer versions so unfortunately we're still dealing with this :)

Configuration:

AS: Flamingo AGP: 8.0.0 Gradle: 8.0 Java: AS embed JDK (17) Kotlin: 1.8.20 Jacoco: 0.8.8 Hilt: 2.45

Previously I was able to use asm_instrumented_project_classes workaround for setting the class directory of my kotlin classes but on AGP 8.0.0 this stopped working (the folder was no longer being generated).

When switching back to the tmp/kotlin-classes directory for kotlin classes, I started seeing the [WARN] Execution data for class xxx/xxx/xxx/xxx does not match error again, listing every class I added @AndroidEntryPoint to, and not having proper coverage data for these classes.

I've switched to using the "Lifted" workaround from #7/#9 and that seems to be working well (if not slightly annoying to make work with the navigation library), but obviously a proper workaround would be greatly appreciated...

I've created a similar app to #12, using the latest current versions of AGP, Kotlin, Hilt, etc.

The same issue exists still.

Apologies, I forgot to include the link. Here it is: https://github.com/ZOlbrys/JacocoHiltEntryPointCoverageTestApp

#21 - that seems to work, I can make a branch in the test app.

I am not familiar with this dir/path, is it safe to use? Is this changing again in the future?

I've filed a feature request for AGP to allow generating a single coverage report for unit and device tests, please +1 it: https://issuetracker.google.com/329683722. This should avoid adding custom build logic.

Workaround until https://issuetracker.google.com/329683722 is fixed:

In order to generate a unified report yourself, you should fetch .class files using AGP APIs. Here is an example (based on AGP recipe):

private val coverageExclusions = listOf(
    // Android
    "**/R.class",
    "**/R\$*.class",
    "**/BuildConfig.*",
    "**/Manifest*.*"
)

androidComponentsExtension.onVariants { variant ->
  val myObjFactory = project.objects
  val allJars: ListProperty<RegularFile> = myObjFactory.listProperty(RegularFile::class.java)
  val allDirectories: ListProperty<Directory> = myObjFactory.listProperty(Directory::class.java)
  val reportTask =
    tasks.register("jacoco${variantName.capitalize()}Report", JacocoReport::class) {
        classDirectories.setFrom(
                allJars,
                allDirectories.map { dirs -> 
                    dirs.map { dir ->
                      myObjFactory.fileTree().setDir(dir).exclude(coverageExclusions)
                    }
                }
        )
    }

  variant.artifacts.forScope(ScopedArtifacts.Scope.PROJECT)
        .use(reportTask)
        .toGet(
            ScopedArtifact.CLASSES,
            { _ -> allJars },
            { _ -> allDirectories },
        )
}
