在尝试编译Spark程序时遇到错误，提示'object apache is not a member of package org'。错误出现在导入Spark相关包的地方，包括SparkConf和SparkContext。问题可能由于本地Maven仓库路径过长或深层导致，解决方案是将本地仓库路径改为更简洁的位置，如'E:StudyBigData epository'。

原因：本地仓库有问题。很可能是原来的本地仓库路径太长了太深了，仓库本身没问题，因为我把原来的仓库拷贝到E:\Study\BigData\目录下，就能正常使用。

解决方法：

原来spark工程的maven本地仓库是：E:\Study\BigData\heima\stage5\1scala\scala3\spark课程需要的maven仓库\SparkRepository

后来我修改为：E:\Study\BigData\repository 就可以了。
