scala - 在 sbt build 上找不到类

问题描述

我在我的 sbt 构建中收到以下错误。我正在尝试配置登录我的 Scala 项目的 logentries。我已经添加了所有必需的依赖项，但仍然出现以下错误

ch.qos.logback.core.util.DynamicClassLoadingException：无法实例化类型 com.logentries.log4j.LogentriesAppender

Caused by: java.lang.NoClassDefFoundError: org/apache/log4j/AppenderSkeleton

有什么建议么？

我的依赖项列表是

解决方案

使用下述内容创建文件名 log4j.properties。并将它放在它应该工作的 classPath 中。

# Root logger option
log4j.rootLogger=INFO, stdout

# Direct log messages to stdout
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.out
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n
