我遇到一个问题,maven在运行JUnit测试时没有找到slf4j类:
22:20:05,412 |-INFO in ch.qos.logback.classic.LoggerContext[default] - Could NOT find resource [logback.groovy]
22:20:05,412 |-INFO in ch.qos.logback.classic.LoggerContext[default] - Found resource [logback-test.xml] at [file:/home/ram/src/2dd/java/dd2/target/test-classes/logback-test.xml]
22:20:05,526 |-INFO in ch.qos.logback.core.joran.action.AppenderAction - About to instantiate appender of type [ch.qos.logback.core.RollingFileAppender]
22:20:05,527 |-ERROR in ch.qos.logback.core.joran.action.AppenderAction - Could not create an Appender of type [ch.qos.logback.core.RollingFileAppender]. ch.qos.logback.core.util.DynamicClassLoadingException: Failed to instantiate type ch.qos.logback.core.RollingFileAppender
但是,slf4j jar文件正被添加到类路径中:
