Current Behavior

I’m working on a kotlin multiplatform project, when I try to write some unit test by using MockK, I got the Unresolved reference: xxx error when I run the ./gradlew :common:build, don’t actually know this case relates to this issue(#58 ) or not.

...

Steps to Reproduce

You can clone the project https://github.com/littleGnAl/accounting-multiplatform/tree/littlegnal/common-test.

Uncomment the https://github.com/littleGnAl/accounting-multiplatform/blob/littlegnal/common-test/android/common/src/commonTest/kotlin/com/littlegnal/accountingmultiplatform/data/SqlDelightManagerTest.kt.

Then run the ./gradlew :common:build to reproduce
