How to add a shapshot to build result (without TeamAccept)

I'm trying to implement the following build scenario with JBE
step 1 - Accept latest changes in source component in build workspace
step 2 - Compile java code
step 3 - create jar files
step 4 - check-in jar files in bin component
step 5 - take snapshot in the build workspace
step 6 - publish snapshot to build result

Steps 1 through 5 are operational, but publishing the snapshot created in step 5 to the build result is problematic. TeamAccept creates a snapshot and publishes it to the build result, but that is to early in the scenario resulting in a snapshot that combines the latest accepted changes with the jar's of the previous build.

Thanks for advising if there is an ant task or scm command other than TeamAccept that enables publishing of a snapshot to a build result ?
