So we get below NoClassDefFoundError if we upgrade slf4j => 1.8.0 or higher.

logback-classic-1.3.0-alpha4.jar
logback-core-1.3.0-alpha4.jar
slf4j-api-1.8.0-alpha2.jar

java.lang.NoClassDefFoundError: org/slf4j/impl/StaticLoggerBinder displayed in logs

However below existing version combination works

logback-classic-1.2.3.jar
logback-core-1.2.3.jar
slf4j-api-1.7.25.jar

Any idea why slf4j(1.8.0 or higher) does not work when used with logback-classic(1.3.0-alpha4) pls?


Actually we have upgraded as part of our jdk8 => jdk11 upgradation exercise .

logback 1.3.x series require slf4j-api version 2.0.x

Also, logback-classic natively implements the SLF4J API, so I believe you don't need to add slf4j-api in your pom.xml explicitly.
