kotlinx.coroutines: Multi-version jar file problem with Android SDK

UPDATE (from @elizarov): JEP 238 multi-version jars seem to be causing various issue with google toolchain. Reported thus far:

MethodHandle.invoke and MethodHandle.invokeExact are only supported starting with Android O (--min-api 26)
Program type already present: kotlinx.coroutines.experimental.InvokeOnCancellation, Program type already present: kotlinx.coroutines.experimental.internal.LockFreeMPMCQueueNode, etc
class name (kotlinx/coroutines/experimental/scheduling/LimitingDispatcher) does not match path (META-INF/versions/9/kotlinx/coroutines/experimental/scheduling/LimitingDispatcher.class), etc

ORIGINAL REPORT:

Trying to compile an Android project with min SDK 19 and the newly released 0.25.0 I suddenly receive the following build error:

MethodHandle.invoke and MethodHandle.invokeExact are only supported starting with Android O (--min-api 26)

Android Studio: 3.1.4 Android Gradle Plugin: 3.1.4

We’re going to revert multirelease JAR

Indeed the complete switch to multi-version JARs seems a bit premature. Especially when multiple developers are working on a project, it’s not easy to switch to alpha-level build components.

Is there a workaround for this issue without using alpha-stability components?

Not even Grade plugin 3.2 is out, so I imagine that stable version for 3.3 will take a long time.

Use kotlinx.coroutines version 0.25.3.

In my case it was 0.25.0 coroutines. 0.24.0 – is OK.

@elizarov Would it be possible to release an artifact of the coroutines library for android without multi-version jar? Like @matejdro said I, too, hesitate to use an alpha version of the build toolchain for my production application.

Can you please tell me how to exclude these classes? I’ve tried different solutions but nothing seems to work:

android {
    sourceSets.main.java.filter.exclude 'META-INF/**/*'

    packagingOptions {
        exclude 'META-INF/**/*'
    }
}
