It looks like you probably have two versions of the apache commons-io.X.X.jar file in your userlib. Take a look in there, and remove the ones with the oldest version numbers, keeping the one with the highest version number. You should now be able to compile your project successfully.

This error usually occurs when upgrading a module or adding a new module that includes a newer version of the .jar file.

Hope this helps.
