这个包在maven引入的时候是provide的，运行main函数的时候会有如下错误：
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/spark/sql/SparkSession at Rdd01.main(Rdd01.java:16) Caused by: java.lang.ClassNotFoundException: org.apache.spark.sql.SparkSession at java.net.URLClassLoader.findClass(URLClassLoader.java:382) at java.lang.ClassLoader.loadClass(ClassLoader.java:418) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:355) at java.lang.ClassLoader.loadClass(ClassLoader.java:351) ... 1 more
解决方法，在我们的Edit Configuration选项中勾选Include dependencies with “Provided” scope即可
