SDK incompatible with Kotlin 1.6.x

[cloudshiftchris]

Describe the bug

Using AWS Kotlin SDK 0.17.9 as part of a Gradle plugin. Gradle embeds Kotlin as part of its distribution; the Kotlin version is tied to the Gradle version. As of latest Gradle 7.5.1, Kotlin 1.6.21 is embedded.

When using the AWS Kotlin SDK the below exception is encountered due to the SDK being compiled against Kotlin 1.7.x.

Thanks for the bug report. Indeed this was previously encountered here with users upgrading to 1.7.x. We decided to resolve the previous issue by updating to 1.7.x and just rolling forward.

I'm not sure if there are any other uses but we can take a look at removing our usage of measureTimedValue to see if we can restore Kotlin 1.6.x compatibility. We will discuss and decide how to resolve.

In the meantime you might try 0.16.4-beta which was the last release before upgrading to 1.7.x

[cloudshiftchris]

Thanks for the prompt response. Indeed, 0.16.4 works w/ Gradle 7.5.1 / Kotlin 1.6.21 - thanks for the advice.

Is there a compatibility statement/matrix/plan, e.g. n-2 versions are supported, etc?

[aajtodd]

There is no compatibility statement on Kotlin versions right now as we are still in developer preview and plan to take new Kotlin versions eagerly until GA.

[aajtodd]

We've published a versioning policy that discusses Kotlin support.

As we march towards a GA release we will continue to take new releases of Kotlin as they come. We will not be pursuing backwards compatibility with older Kotlin versions prior to our GA date (and possibly after as indicated in our policy).
