Kotlin test coverage not reported for Java production code with JaCoCo

[realdadfish]

This is my configuration:

plugins {
    id("org.jetbrains.kotlinx.kover")
}

val configuration = extensions.create("glscoverage", GlsCoverageExtension::class.java)

afterEvaluate {
    kover {
        // not working
        useJacoco("0.8.11")
    }

    val expected = configuration.expectedCoverage.get()
    val threshold = configuration.coverageThreshold.get()
    val minBound = (expected - threshold).coerceAtLeast(0)
    val maxBound = (expected + threshold).coerceAtMost(100)

    koverReport {
        defaults {
            mergeWith(configuration.buildVariant.get())
        }

        filters {
            excludes {
                annotatedBy("*Generated*")
                classes(configuration.classFilter.get())
            }
        }

        verify {
            rule {
                minBound(minBound)
                maxBound(maxBound)
            }
        }

        androidReports(configuration.buildVariant.get()) {}
    }

    tasks.withType(Test::class.java).configureEach {
        finalizedBy(tasks.named("koverXmlReport"))
    }
}

Now I have separate Kotlin and Java source sets for my mixed-language module configured, i.e. src/{main,test}/{kotlin,java} and I have a Kotlin test that tests various Java source files. With the above configuration the coverage for these Java source files is reported as 0, even if I move the test from src/test/kotlin to src/test/java, however, if I comment out useJacoco above and let the IJ coverage processor do it's thing, the coverage of the classes in question is properly reported.

Environment

• Kover Gradle Plugin version: 0.7.5
• Gradle version: 8.5
• Kotlin project type: Kotlin/Android
• Coverage Toolset (if customized in build script): Kover, Jacoco (0.8.11)

Hi,
try to move the kover { block from the afterEvaluate { to the top level, like this:

...
val configuration = extensions.create("glscoverage", GlsCoverageExtension::class.java)
kover {
    // not working
    useJacoco("0.8.11")
}

afterEvaluate {
    val expected = configuration.expectedCoverage.get()
    ...
}

Didn't made a difference, same result. The coverage in Jacoco is still missing:

Is this a multi-module project?

[realdadfish]

The component in question has just one module, the app module. The convention plugin is applied on the app module level.

Could you please provide a reproducer project?

Here it is: https://github.com/realdadfish/kover-issue-530/tree/main

It seems to be triggered by Robolectric on the test classpath. If I have two regular Java/Kotlin unit tests, both execute fine and the coverage shows that both methods are covered. If I let each test run with the Robolectric runner, neither test shows coverage on the class with JaCoCo, but both tests show coverage with the built-in coverage tool

Many thanks!

Fixed in 0.7.6
