я пытаюсь выполнить свой проект Kafka Spark. Я получаю ниже ошибки:

Exception in thread "main" java.lang.NoClassDefFoundError: org/spark_project/guava/cache/CacheLoader
    at org.apache.spark.SparkConf.loadFromSystemProperties(SparkConf.scala:73)
    at org.apache.spark.SparkConf.<init>(SparkConf.scala:68)
    at org.apache.spark.SparkConf.<init>(SparkConf.scala:55)

Я попробовал ниже методы, которые уже просят на форуме: 1) Добавлено

2) Удалил jarfile google.guava из пути сборки в eclipse и снова добавил как внешний jar.

Но ниже два метода не помогли в моем случае.

Пожалуйста, кто-нибудь, помогите мне в решении этой проблемы. Спасибо заранее
