The jar file is locked because it is referenced in a classloader. The lock will be released once the classloader is garbage collected but that will not happen until all references to all classes defined by the jar are no longer referenced. If the jar file in question is referenced by Ant then chances are that your file will not be released until the Ant Project instance is no longer in use. The solution to the problem is to handle the creation and updating operations under two distinct projects. One project handles the creation of a new jar file, and the second project handles the replication of the jar (with the assumption that your second project does not include a classpath reference to the jar file).
