Suggest to read Binary repository management Refcard first.
You need define your strategy for your folders and wars (web application), it is already good to use different repo for different purpose (snapshot/release)
The process for maintenance is simple
- fix the bug and increase the version, send to the
libs-snapshot-local
for testing - after testing, a.k.a QA passed, the packages are promoted to release/stage repo
libs-release-local
again for public use again.
In this case, bug fix is the same as normal development procedure.
or you can refine the questions to make your questions more clear.
