我对大数据和spark非常陌生，下面是我如何尝试获得spark课程的

SparkConf conf = new SparkConf().setMaster("local").setAppName("SaavnAnalyticsProject");
sparkSession = SparkSession.builder().config(conf).getOrCreate();

这就是我犯的错误
使用spark的默认log4j配置文件：org/apache/spark/log4j-defaults.properties 20/02/03 02:29:40 info sparkcontext:在线程“main”java.lang.nosuchmethoderror:com.google.common.base.joiner.on（c）lcom/google/common/base/joiner中运行spark版本2.3.0异常；在org.apache.hadoop.metrics2.lib.uniquenames。java:44)在org.apache.hadoop.metrics2.lib.defaultmetricssystem.（defaultmetricssystem。java:41)在org.apache.hadoop.metrics2.lib.defaultmetricssystem.（defaultmetricssystem。java:36)在org.apache.hadoop.security.usergroupinformation$ugimetrics.create（usergroupinformation。java:120)在org.apache.hadoop.security.usergroupinformation.（usergroupinformation。java:236)在org.apache.spark.util.utils$$anonfun$getcurrentusername$1.apply（utils。scala:2464)在org.apache.spark.util.utils$$anonfun$getcurrentusername$1.apply（utils。scala:2464)在scala.option.getorelse（option。scala:121)在org.apache.spark.util.utils$.getcurrentusername（utils。scala:2464)在org.apache.spark.sparkcontext。scala:292)在org.apache.spark.sparkcontext$.getorcreate（sparkcontext。scala:2486)在org.apache.spark.sql.sparksession$builder$$anonfun$7.apply（sparksession。scala:930)在org.apache.spark.sql.sparksession$builder$$anonfun$7.apply（sparksession。scala:921)在scala.option.getorelse（option。scala:121)在org.apache.spark.sql.sparksession$builder.getorcreate（sparksession。scala:921)在saavnalytics.saavnalyticsmain.main（saavnalyticsmain。java:55)
这是我的pom.xml

我已经显式地添加了google-collect-0.5.jar和com.google.collections.jar。
知道我哪里出错了吗？
