I took the description below from the plugin Wiki because I have a similar problem. I need to archive all unit test logs for our QA after running a unit test project even if some tests fail without cluttering my Jenkins with hundreds of build logs.

Original problem from the Wiki:

My Jenkins job has the following build steps:

1. Execute Windows batch command (a set of simple commands terminated by an 'exit X' statement, where X can be zero for successful builds and non-zero for failed builds)

2. Deploy artifacts from workspace to remote directories

If the exit statement at the end of my batch commands is non-zero then the artifacts are NOT deployed. I would like to be able to deploy artifacts following a failed build because although the build failed there will be build log files indicating the reason for failure as well as partial artifacts.
