Question

当我使用aws athena sdk，aws java athena sdk，log4j构建项目时，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

和我的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

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

依赖项：

        <dependency>
            <groupId>software.amazon.awssdk</groupId>
            <artifactId>athena</artifactId>

构建aws athena项目时，log4j出现错误
