Unknown dependency - kotlinx-coroutines-core-jvm

[skyerday]

I met a build time issue with class duplicated with kotlinx-coroutines-core-jvm and kotlinx-coroutines-core. And I list the dependencies

./gradlew :app:dependencies

|    |    |    +--- com.babylon.certificatetransparency:certificatetransparency-android:0.3.0
|    |    |    |    +--- com.babylon.certificatetransparency:certificatetransparency:0.3.0

|    |    |    |    |    |    +--- org.jetbrains.kotlin:kotlin-stdlib:1.4.0 (*)
|    |    |    |    |    |    \--- org.jetbrains.kotlin:kotlin-stdlib-jdk7:1.4.0 (*)

|    |    |    |    \--- org.jetbrains.kotlinx:kotlinx-coroutines-core:1.3.9 (*)

And I also google org.jetbrains.kotlinx:kotlinx-coroutines-core-jvm but found nothing related. For now, I try these to workaround class duplicated issue

    implementation('com.babylon.certificatetransparency:certificatetransparency-android:0.3.0') {
        exclude group: 'com.babylon.certificatetransparency', module: 'certificatetransparency'
    }

    implementation('com.babylon.certificatetransparency:certificatetransparency:0.3.0') {
        exclude group: 'org.jetbrains.kotlinx', module: 'kotlinx-coroutines-core-jvm'
    }

I upgrade gradle to 6.1.1 and android gradle plugin to 4.0.1, the duplicated issue is gone.
