allure cannot find 'webappsourcedirectory' in class org.mortbay.jetty.plugin.jettywebappcontext

Добрый день. Пытаюсь подключить allure по этой статье artkoshelev.github.io/posts/hello-allure после команды mvn clean test site jetty:run тест проходит, но валится на этапе составления отчёта, а именно ошибка cannot find 'webappsourcedirectory' in class org.mortbay.jetty.plugin.jettywebappcontext

Я новичок, подскажите пожалуйста, уже 2 дня пытаюсь решить эту пробему, гуглёж не помог..( Прикладыю pom.xml:

    <compiler.version>1.8</compiler.version>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <allure.version>1.4.0</allure.version>
    <aspectj.version>1.8.2</aspectj.version>
    <webdriver.driver>chrome</webdriver.driver>
</properties>
