picketbox jar is assembled from several picket box modules, among them picketbox-spi-bare and picketbox-bare.
picketbox-infinispan defines picketbox-spi-bare and picketbox-bare as mandatory dependencies.

Including in the project picketbox and picketbox-infinispan dependencies results in adding to project dependencies picketbox-spi-bare and picketbox-bare, whose content is already present in picketbox dependency.

The solution is to make picketbox-spi-bare and picketbox-bare optional dependencies of picketbox-infinispan, or better create another assembled jar which would contain content of picketbox and picketbox-infinispan
