Generating report for multi-module project with flavors

[IlyaPavlik]

Describe the bug
Build failed when I try to generate html report for multi module project with flavors.
./gradlew clean :app:koverHtmlReportDemoDebug

Errors

Could not determine the dependencies of task ':app:koverHtmlReportDemoDebug'.

          - Variant 'koverSetupRelease' capability JaCoCoExample:libModule:unspecified:
              - Incompatible because this component declares attribute 'kotlinx.kover.setup.name' with value 'release' and the consumer needed attribute 'kotlinx.kover.setup.name' with value 'demoDebug'

Expected behavior
Should generate merged html report

Reproducer
app module

plugins {
    id 'org.jetbrains.kotlinx.kover' version '0.7.0-Alpha'
}

flavorDimensions "version"
    productFlavors {
        demo {
            dimension "version"
        }
        full {
            dimension "version"
        }
    }

dependencies {
    kover project(":libModule")
}

libModule

plugins {
    id 'org.jetbrains.kotlinx.kover' version '0.7.0-Alpha'
}

Environment

• Kover Gradle Plugin version: 0.7.0-Alpha
• Gradle version: gradle-7.5
• Kotlin project type: Kotlin/Android
• Coverage Engine version (if customized in build script): DefaultJacocoEngine
• Other context important for this bug: -

We are also seeing this for our project in 0.7.0-Alpha, Most of modules just use debug and release but one module has productFlavours for uat,staging,prod

This one module :config with flavours can't be merged with the others modules.

I've also tried missingDimensionStrategy("environment", listOf("uat", "staging", "prod")) in the module where we are setting up kover dependencies but still get the following error:

Could not resolve all task dependencies for configuration ':kover:koverAggregatedSetupDebug'.
   > Could not resolve project :config.
     Required by:
         project :kover
      > The consumer was configured to find attribute 'kotlinx.kover.setup.name' with value 'debug'. However we cannot choose between the following variants of project :config:
          - prodDebugApiElements
          - prodDebugRuntimeElements
          - prodReleaseApiElements
          - prodReleaseRuntimeElements
          - stagingDebugApiElements
          - stagingDebugRuntimeElements
          - stagingReleaseApiElements
          - stagingReleaseRuntimeElements
          - uatDebugApiElements
          - uatDebugRuntimeElements
          - uatReleaseApiElements
          - uatReleaseRuntimeElements

Hi,
unfortunately, the alpha version supports only multi-module projects that have completely identical build variants.

[wezley98]

@shanshin That's fine, will this be a future feature?

[shanshin]

I think it will be possible to implement this.

Now we are collecting feedback and the most common use cases.

Fixed in 0.7.0-Beta
Please note that the DSL has been modified compared to Alpha version.
