AWS SDK for Kotlin
This repo contains the AWS SDK for Kotlin and its public roadmap.
Getting Started
See the Getting Started Guide to learn how to use the AWS SDK for Kotlin in your program.
Feedback
The SDK uses GitHub Issues to track feature requests and issues with the SDK. In addition, we use GitHub Projects
to provide a high level overview of our roadmap and the features we are actively working on.
You can provide feedback or report a bug by submitting an issue.
This is the preferred mechanism to give feedback so that other users can engage in the conversation, +1 issues, etc.

Versioning
See our VERSIONING policy for how the SDK is versioned.
Development
Generate SDK(s)
Generated sources are not checked into the repository, you first have to generate the clients before you can build them.
A step-by-step guide is available that demonstrates building the AWS DynamoDB service, or if
you have a good working knowledge of Gradle, see below:
./gradlew --no-daemon :codegen:sdk:bootstrap
NOTE: This task will respect the AWS services specified by project properties. See options below.
NOTE: To re-run codegen for the same set of services multiple times add the --rerun-tasks
flag.
After generating the services you care about they are available to build:
e.g.
./gradlew :services:lambda:build
Where the task follows the pattern: :services:SERVICE:build
To see list of all projects run ./gradlew projects
Generating a single service
See the Build Properties below to specify this in a config file.
./gradlew --no-daemon -Paws.services=+lambda :codegen:sdk:bootstrap
Testing Locally
Testing generated services generally requires publishing artifacts (e.g. client-runtime) of smithy-kotlin
, aws-crt-kotlin
, and aws-sdk-kotin
to maven local.
Generating API Documentation
API documentation is generated using Dokka which is the official documentation tool maintained by JetBrains for documenting Kotlin code.
Unlike Java, Kotlin uses its own KDoc format.
To generate API reference documentation for the AWS Kotlin SDK:
./gradlew --no-daemon --no-parallel dokkaHtmlMultiModule
This will output HTML formatted documentation to build/dokka/htmlMultiModule
NOTE: You currently need an HTTP server to view the documentation in browser locally. You can either use the builtin server in Intellij or use your favorite local server (e.g. python3 -m http.server
). See Kotlin/dokka#1795
Build Properties
You can define a local.properties
config file at the root of the project to modify build behavior.
Property | Description |
---|
compositeProjects | Specify paths to repos the SDK depends upon such as smithy-kotlin |
aws.services | Specify inclusions (+ prefix) and exclusions (- prefix) of service names to generate |
aws.protocols | Specify inclusions (+ prefix) and exclusions (- prefix) of AWS protocols to generate |
Composite Projects
Dependencies of the SDK can be added as composite build such that multiple repos may appear as one
holistic source project in the IDE.
compositeProjects=../smithy-kotlin
Generating Specific Services Based on Name or Protocol
A comma separated list of services to include or exclude for generation from codegen/sdk/aws-models may
be specified with the aws.services
property. A list of protocols of services to generate may be specified
with the aws.protocols
property.
Included services require a '+' character prefix and excluded services require a '-' character.
If any items are specified for inclusion, only specified included members will be generated. If no items
are specified for inclusion, all members not excluded will be generated.
When unspecified all services found in the directory specified by the modelsDir
property are generated.
Service names match the filenames in the models directory service.VERSION.json
.
Some example entries for local.properties
:
aws.services=+lambda
aws.services=-location,-dynamodb
aws.protocols=-restJson1
