Maven - не удалось выполнить цель

Я попытался создать пакет maven из этого источника https://github.com/mpercy/flume-loadgen.
Но, когда я создаю его с помощью mvn clean package, у меня появились такие ошибки:

Я думаю, что в этом случае maven использует неправильный регистратор slf4j. Но я действительно не знаю, как это исправить. Кто-нибудь может помочь? благодарю!
