Use of library from commonMain in Kotlin Multiplatform Project

[joreilly]

Describe the issue

I can include following for example as commonMain dependency in shared module of a Kotlin Multiplatform project and access/use code from JVM and Android code but if I try to use from commonMain source then only certain symbols appear to be resolvable (for example can access StaticCredentialsProvider but not DynamoDbClient). Perhaps this is expected right now?

api("aws.sdk.kotlin:dynamodb:0.9.4-beta")

Yes this is expected right now. The services are built with the Kotlin/JVM plugin still. You should be able to access them from a JVM sourceSet. Most of the runtime itself is implemented with the multiplatform plugin which is why you can access it from common.

Support for other targets is on our roadmap. The best thing you can do right now is to upvote the existing issues with the targets you would like to see supported.

I agree that the ability to use the services in a common sourceSet (targeting only jvm() and android() for now of course) would be useful but it may not come until we get to supporting one of the other KMP targets outright.

Here is a list of all of our existing feature requests @joreilly , and these two are particular to KMP/js and KMP/native support.

Once that's done we should be able to update the service builds to publish as KMP projects (with only JVM target support for now) with all the KMP metadata.

The fix for this issue has been pushed to main and should be included in the next release (likely this week). With that release, it should be possible to reference service clients and related types from common source sets (instead of requiring JVM).

Note that the AWS SDK for Kotlin does yet not support non-JVM targets but they are on our roadmap as #228 and #229.

I see that a 0.16.0 version was released but doesn't look like it's been published yet?

[aajtodd]

We were having some issues syncing with maven central, it appears to be available now (e.g. dynamodb-jvm)

NOTE: we accidentally cut this release without the -beta qualifier. Future dev preview releases will use this qualifier again though.

Let me know if it's better to create another issue for this but getting following now when trying (in JVM code) to populate DynamoDb table (on M1 device)....seems related to aws/aws-sdk-java-v2#2942 ?

Unable to unpack AWS CRT lib: java.io.IOException: Unable to open library in jar for AWS CRT: /osx/armv8/libaws-crt-jni.dylib
java.io.IOException: Unable to open library in jar for AWS CRT: /osx/armv8/libaws-crt-jni.dylib

...actually, looks like this is already captured in #473

I'm assuming this probably isn't new behaviour with this version but just that I moved over to using M1 device since I was trying this before.
