example-app: com.android.builder.dexing.DexArchiveBuilderException

[tinyvampirepudge]

when I run coroutine-android demo, I met this Error on building process.
kotlinx.coroutines-master/ui/kotlinx-coroutines-android/example-app

Caused by: com.android.builder.dexing.DexArchiveBuilderException: Failed to process /Users/xxx/.gradle/caches/modules-2/files-2.1/org.jetbrains.kotlinx/kotlinx-coroutines-core/0.25.0/5664ba2d20c6dcc88c912cc9666baa7f03203bcd/kotlinx-coroutines-core-0.25.0.jar

I'm updated Android Gradle Tools version to 3.3.0-alpha04 and Gradle to version 4.9 and it seems that it fixed the problem. Please, check.

I'd try with last alpha 3.3.0-alpha06, Gradle 4.9. Confirm. Fixed.

It seems that Gradle 4.9 requires gradle module format version 0.4, while kotlinx-coroutines-core-common-0.25.0.module uses format 0.3.

Is it currently possible to use coroutines 0.25.0 in a multiplatform project?

@brettwillis looks like you can't go higher than gradle 4.7 to use coroutines atm
