Plugin uses method project.expand for placeholders. But this method works only with project.properties, which doesn't inlcude name and version (it's attributes). filter_resource uses next wrapper which could be used

class ProjectDictWrapper(object):

    def __init__(self, project, logger):
        self.project = project
        self.logger = logger

    def __getitem__(self, key):
        fallback_when_no_substitution_possible = "${%s}" % key
        if hasattr(self.project, key):
            return getattr(self.project, key)
        if self.project.has_property(key):
            return self.project.get_property(key)
        self.logger.warn(
            "Skipping impossible substitution for '{0}' - there is no matching project attribute or property.".format(key))
        return fallback_when_no_substitution_possible
