Configure AWS CRT 기반 HTTP 클라이언트

기본적으로는 Linux, Windows 및 macOS를 비롯한 여러 플랫폼의 바이너리가 포함된 uber-jar of AWS CRT 아티팩트를 aws-crt-client 사용합니다.

<project>

*빨간색으로 표시된 버전을 사용하려는 Java SDK 버전으로 바꿉니다. Maven Central에서 최신 정보를 찾아보세요.

Java 런타임을 AWS CRT 라이브러리의 플랫폼별 버전으로 제한하려면 Uber-jar 옵션을 다음과 같이 변경합니다.

¹빨간색으로 표시된 버전을 사용하려는 Java SDK 버전으로 바꿉니다. Maven Central에서 최신 정보를 찾아보세요.

²Uber-jar 옵션에서 software.amazon.awssdk.crt:aws-crt 제공하는의 버전을 바꿉니다. 다음 단계를 참조하여 AWS CRT 아티팩트 버전을 확인합니다.

³플랫폼의 classifier 값을 값으로 바꿉니다. 사용 가능한 값 목록은 AWS CRT for Java GitHub 페이지를 참조하세요.
