com.amazonaws.transform.JsonErrorUnmarshaller : method <init> (Ljava/lang/Class;) V를 찾을 수 없음

Question

logback-ext-cloudwatch-appender라는 라이브러리를 사용하여 로그백 기반 로그를 AWS Cloudwatch에 보냅니다. 이것은 pom.xml 파일에서 종속성이 어떻게 생겼는지를 나타냅니다.

<dependency> 
     <groupId>org.eluder.logback</groupId> 
     <artifactId>logback-ext-cloudwatch-appender</artifactId> 
     <version>1.0-SNAPSHOT</version> 
    </dependency> 

며칠 전 이러한 오류가 로그에 표시되기 시작했습니다.

AWS 1.11.5로 업그레이드했지만, 해당 릴리스에서 버그가 발견되지 않았습니다.

Answer 1

이 logback-EXT-CloudWatch를-펜더의 현재 버전이 다른 AWS-자바와 하지 호환 AWS-자바 SDK-로그 1.10.2의 특정 버전에 전이 종속성이 밝혀 -sdk 라이브러리 1.11.0 이상. 우리는 다른 많은 aws-java-sdk 라이브러리를 사용합니다. 이와 같은 의존성을 제외했습니다.

그 시점에서 우리는 또 다른 오류가 발생하기 시작했습니다.

의존성을 제외하면 작동하지 않습니다. 나는 현재 1.11.5 aws-java-sdk 라이브러리에 의존하여 logback-ext-cloudwatch-appender 항아리를 포크하고 다시 빌드해야했다. 이전 라이브러리에 대해 빌드 된 logback-ext-cloudwatch-appender jar에 새로운 AWS 종속성을 사용하려고 시도하면 createLogGroup의 메소드 서명 (리턴 유형)이 일치하지 않아 런타임 오류가 발생합니다. 이 작업을 실행하기 위해서, 나는 fork 된 버전에서 소스 코드가 아닌 pom.xml 파일 만 변경해야했습니다.
