我们正在使用一个名为 logback-ext-cloudwatch-appender 的库将我们基于 logback 的日志发送到 AWS Cloudwatch。这就是我们 pom.xml 文件中的依赖关系。

我发现我们已经升级到 AWS 1.11.5,但我找不到任何证据表明该版本中存在此类错误。
原来logback-ext-cloudwatch-appender的当前版本对aws-java-sdk-logs 1.10.2的特定版本有传递依赖,即不 与其他 aws-java-sdk 库 1.11.0 及更高版本兼容。我们确实使用了许多其他 aws-java-sdk 库。我们排除了这样的依赖。

仅仅排除依赖项是行不通的。我不得不分叉并重建依赖于当前 1.11.5 aws-java-sdk 库的 logback-ext-cloudwatch-appender jar。尝试将新的 AWS 依赖项与针对旧库构建的 logback-ext-cloudwatch-appender jar 一起使用会导致 createLogGroup 的方法签名(return 类型)不匹配,从而导致 运行时间错误。为了达到 运行,我只需要在我的分叉版本中更改 pom.xml 文件,而不是源代码。
