Generating merged report for multiproject

[fvillalbacar]

Hello,

Working in an Android project with several modules I was using koverXmlReport to obtain a XML report. For obtaining a single report of all the modules, the following lines where added into the build.gradle.kts file on the root of the project:

subprojects {
    plugins.withId("org.jetbrains.kotlinx.kover") {
        tasks
            .matching {
                it.name == "koverHtmlReport" ||
                    it.name == "koverXmlReport" ||
                    it.name == "koverVerify"
            }.configureEach {
                enabled = false
            }
    }
}

to avoid the generation of report per project, and also:

kover {
    merge {
        allProjects()
    }
}

to obtain the merged report.

Recently I have added a couple of dimensions, so instead of using the instruction koverXmlReport I am using koverXmlReportDimensionADimensionBDebug in order to get the report and to not compile all the variants (CI needs lots of time).

It seems that for that instruction the setting is ignored and generates a report for each module, and not the merged report. Is there any workaround to obtain a single report using the variant instruction?

Environment:
Android Gradle Plugin: 8.13.0
Gradle Wrapper : 9.1.0
Kover version: 9.3.0

Thanks in advance

Hi, sorry for the late answer.

if using merge { ... } is acceptable for you, then you can use it to create a custom report variant, in which you need to add only the necessary targets and Android build variants:

kover {
    merge {
        allProjects()

        createVariant("custom") {
            add("jvm", optional = true) // jvm target presents not in all modules
            add("dimensionADimensionBDebug", optional = true)  // dimensionADimensionBDebug build variant also presents not in all modules
        }
    }
}

Also, you don't have to disable Kover tasks in other models if you call the task using the full path.
Like :koverHtmlReportCustom if merge {} is specified in the root, or :reports:koverHtmlReportCustom if it's specified in reports module
