【问题标题】：something error with log4j while building aws athena project构建 aws athena 项目时 log4j 出现错误

【问题描述】：

当我使用 aws athena sdk、aws java athena sdk、log4j 构建我的项目时，我失败了。这是消息

log4j:ERROR A "org.apache.log4j.ConsoleAppender" object is not assignable to a "com.simba.athena.shaded.apache.log4j.Appender" variable.
log4j:ERROR The class "com.simba.athena.shaded.apache.log4j.Appender" was 
loaded by 
log4j:ERROR [sun.misc.Launcher$AppClassLoader@18b4aac2] whereas object of type 
log4j:ERROR "org.apache.log4j.ConsoleAppender" was loaded by [sun.misc.Launcher$AppClassLoader@18b4aac2].
log4j:ERROR Could not instantiate appender named "A1".

这是我的 pom.xml

还有我的 log4j.properties

log4j.rootLogger=WARN, A1
log4j.appender.A1=org.apache.log4j.ConsoleAppender
log4j.appender.A1.layout=org.apache.log4j.PatternLayout
log4j.appender.A1.layout.ConversionPattern=%d [%t] %-5p %c -  %m%n
# Turn on DEBUG logging in com.amazonaws.request to log
# a summary of requests/responses with AWS request IDs
log4j.logger.com.amazonaws.request=DEBUG

非常感谢

【问题讨论】：

您的代码在哪个上下文中运行会引发此异常？看起来您的应用程序想要使用 Amazon 特定的记录器。这个错误是来自您的应用程序还是来自亚马逊部署的服务？
这是我的申请。我认为 log4j.properties 可能有问题，因为如果配置不包含“amazonaws.request”，它不会抛出错误

【解决方案1】：

请尝试使用以下 log4j.properties

### Appender
log4j.appender.stdout=com.simba.athena.shaded.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.out
log4j.appender.stdout.layout=com.simba.athena.shaded.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n
### Log Levels
log4j.rootLogger=info, stdout
