java.lang.ClassNotFoundException: ch.qos.logback.classic.spi.ThrowableProxy?

Question

while starting my weblogic(having my app war file containing logback-classic-1.0.1.jar),i am getting below exception.Any suggestion ?

Answer 1

I have been getting this same error when breaking out (ctrl-c) from Dropwizard server, I finally learned why I get it.

My Dropwizard is build into one fat jar, that I build with Gradle, and when running server on my local computer I run it directly from build/libs/...fat.jar

So this exception occurs when I have changed source code, built app-server again, and Gradle has overwritten the same jar I am currently running with "java -jar ...", so it's not that weird that classes that haven't been used before that session will not load ok :)
