Support for kotlin-multiplatform plugin?

[henriquenfaria]

Does this plugin support multiplatform kotlin projects using the kotlin-multiplatform plugin?

I don't know. Have you tried? If not it's something we can add.

[henriquenfaria]

It didn't work out of the box. I made some progress by adding org.jetbrains.kotlin.multiplatform check in the isKotlinAndroid method:

protected static boolean isKotlinAndroid(final Project project) {
        final boolean isKotlinAndroidProject = project.plugins.hasPlugin('org.jetbrains.kotlin.android')
        final boolean isKotlinMultiplatform = project.plugins.hasPlugin('org.jetbrains.kotlin.multiplatform')
        return isKotlinAndroidProject || isKotlinMultiplatform
}

After this change, the plugin was able to correctly parse the subproject and generate a sane jacoco report. However, the jacocoTestReportMerged task isn't working, it generates an empty report in the project root.

I've done all those tests using this code base.

I can create a PR so we can discuss this in there if you prefer.

It should probably be a separate method and then be applied.

Also without your changes? If I remember correctly, others have also stated that they've had problems with that task.

Sure let's get this rolling!

Yes, just tested it without my changes and it generated an empty report. I guess you are right about it being broken already.

I've just created a PR with my changes.

Thanks for adding support in #141

I'm not sure if it is the right place to ask it, but some of you people had used this plugin in a Kotlin Multiplatform with JVM Target? On Android Target it applies pretty good, but I'm in some trouble with JVM Targets.

@hugonardo I also had trouble getting this plugin to generate reports for my JVM targets.

The following worked for me:

plugins {
    kotlin("multiplatform")
    id("com.android.library")
    id("com.vanniktech.android.junit.jacoco")
}

tasks.create<JacocoReport>("jacocoTestReport") {
    dependsOn("jvmTest")
    reports {
        csv.isEnabled = false
        xml.isEnabled = true
        html.isEnabled = true
    }
    classDirectories.setFrom(file("${buildDir}/classes/kotlin/jvm/main"))
    sourceDirectories.setFrom(files("src/commonMain", "src/jvmMain"))
    executionData.setFrom(files("${buildDir}/jacoco/jvmTest.exec"))
}

kotlin {
    jvm()
    android()

    sourceSets {
        // ...
    }
}

Then I generated reports for JVM and Android targets via: ./gradlew jacocoTestReport jacocoTestReportDebug
