Ошибка MAVEN при загрузке примеров dl4j

Прежде чем я задам вопрос, позвольте мне сказать, что я совершенно новичок в DL4J, maven и java, поэтому, пожалуйста, смиритесь с моим глупым вопросом.

Я пытаюсь установить dl4j-примеры с помощью команды mvn clean install, но получаю следующую ошибку:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.5.1:compile (default-compile) on project datavec-examples: Fatal error compiling: java.lang.NoClassDefFoundError: com/sun/tools/javac/file/BaseFileObject: com.sun.tools.javac.file.BaseFileObject -> [Help 1]

Теперь я не понимаю, получаю ли я эту ошибку из-за java или maven?
