Let's say you logback.xml is in the lib folder and lib folder full path suppose as "/opt/TestApp/lib"
Your classpath should include /opt/testApp/lib

I could be wrong, but I seem to recall that you cannot use the -cp flag when using -jar. I think it tries to get the classpath from the JAR's manifest.

The problem is that its not reliable to put the logback.xml into the
jar. Is there a way to do that with command line? I tried with java
-cp . -jar dist\AntTest.jar which was also not working. The
logback.xml was located in .
