Test Source Directories for Multi Dimension Flavors not recognized in Android Studio

[rgo...@lapresse.ca]

I have an issue with test and androidTest source directories for multi-dimension flavors.

Given the following flavors:

    flavorDimensions "taste", "serving"

    productFlavors {

        chocolate {

            flavorDimension "taste"

        }

        strawberry {

            flavorDimension "taste"

        }

        kiwi {

            flavorDimension "taste"

        }

        sample {

            flavorDimension "serving"

        }

        whole {

            flavorDimension "serving"

        }

    }

There are no issues with "non-test" source directories (of any flavor combination) being recognized in Android Studio: 

src/sample, src/whole, src/chocolate, src/strawberry, src/kiwi, 

src/chocolateSample, src/chocolateWhole, src/strawberrySample, src/strawberryWhole, src/kiwiSample, src/kiwiWhole

My issue is with "test" source directories.  

Only single dimension flavors are recognized: src/testSample, src/testWhole, src/testChocolate, src/testStrawberry, src/testKiwi.  

Multi-Dimension flavors are not:  src/testChocolateSample, src/testChocolateWhole, src/testStrawberrySample, src/testStrawberryWhole, src/testKiwiSample, src/testKiwiWhole

This is also the case for the "androidTest" equivalent source directories.

I am under the impression that it is the app.iml which is not correctly generated.  While understanding that we should NEVER do this, the folders are correctly recognized if I were to manually add in the missing entries.

Why should this work with non-test source directories but fail with test source directories?  Is this a known issue or a limitation by the gradle plugin?

I tried researching this, but only found topics related single flavor dimensions for test source folders or mult-dimension flavors for non-test source folders.  There is nothing with regards to multi-dimension flavors for test source folders.

Thanks,

This is fixed in 1.3, you can try it out with 1.3.0-beta3. It also comes with a task called :app:sourceSets that prints out all the source sets that Gradle would recognize. In your case the output look like this.

Additional tip: remember you can use android.variantFilter { ... } to reduce the number of variants. See the DSL reference and old release notes for details.

Hi Michal:

Thanks for your response on this issue.

I have since updated to Android Studio 1.3.1 and this problem remains.

Multi-Flavor Test Source Directories are still not recognized in this version.

Hello Again:

The gradle :app:sourceSets task is also not recognized.

I finally got this working.

It turns out I was compiling against the wrong version of gradle.

dependencies {
    classpath 'com.android.tools.build:gradle:1.3.0'
}

Multi-Flavor Variants are working since this update.

test

testChocolate

testChocolateSample

testChocolateSampleDebug

are all correctly recognized.

testDebug

testChocolateDebug

testSampleDebug

are not recognized (not in as non-test directories) but I understand this to be normal behaviour since we are required to "complete" the variant with the entire multi-flavor (not a partial flavour) when joining to a BuildType.

Thanks,

Ryan
