Detected both log4j-over-slf4j.jar AND slf4j-log4j12.jar

问题

I have used geotools library, in my project I have added all the dependencies to the buildpath

Downloaded the libraries from Sourseforge. Added the same to the library, When I try to execute the application, I am getting the below error.

    SLF4J: Detected both log4j-over-slf4j.jar AND slf4j-log4j12.jar on the class path, preempting StackOverflowError. 
SLF4J: See also http://www.slf4j.org/codes.html#log4jDelegationLoop for more details.

What I have tried sofar…,

as suggested in this accepted answer, I have added the exclusions. Still having the same error.

I don't have any dependency with them, even I have removed both the jar files, still the error remains same!!
