Mar file was correctly deployed.

To remove this warning, deleted/moved one of the libraries (slf4j-simple-1.7.12.jar). 

Is it correct to do this or if there is an other solution?

Environment

All supported DevTest releases.

Cause

This message says that, the same class file is resolved in 2 different JARs.

Resolution

 

These messages can be safely ignored. 

It is recommended NOT to alter the contents of the DevTest library folders unless it has been suggested by product support or other product SME from Broadcom.

Restore the JAR into its original location and restart DevTest components.
