We use the artifactory plugin and have ant ANT build step defined with a target of [build.all]

When the job is building and we want to change the configuration, the build step will be reflected with targets of [build.all -lib "E:/Jenkins/workspace/artifactory-plugin/2.0.5" -listener org.jfrog.build.extractor.listener.ArtifactoryBuildListener ]

It seems that this information is dynamically entered during build time, however if we click save on a job configuration this information will be persisted. If this happens multiple times, then the job target will contains duplicate copies of this information.
