Incompatible with rebuild plugin / handling of emtpy parameter values #2

For artifacts without classifiers the classifier parameter seems to be set to null and not empty an string. This works fine when creating a new build, but when trying to rebuild a previous build I get the below exception. I'm not sure if this bug should be fixed in this plugin or the Rebuild plugin, but I thought I'd mention it here first since this is the plugin in the stacktrace.

java.lang.IllegalArgumentException: Null value not allowed as an environment variable: MY_ARTIFACT_CLASSIFIER
