users can override ZK dependencies without excluding jar

Steps to Reproduce

Since both zpoi and zss depends on zcommon, when users change ZK dependent version, they have to exclude zcommon from zpoi
 

Current Result

if no exclusion, a project will load built-in version of zcommon, not the overridden version.
This might cause some troubles sometimes.
 

Expected Result

users just need to override zk version only, no need extra exclusion
 

Debug Information

• zpoiex also requires zcommon
