文件打包时，为什么不能导入这些包？

Question

import org.apache.commons.compress.archivers.ArchiveEntry; 
import org.apache.commons.compress.archivers.zip.Zip64Mode; 
import org.apache.commons.compress.archivers.zip.ZipArchiveEntry; 
import org.apache.commons.compress.archivers.zip.ZipArchiveInputStream; 
import org.apache.commons.compress.archivers.zip.ZipArchiveOutputStream; 

Answer 1

要确认相关的jar文件是否导入了

Answer 2

导入的jar包错了。大神们有这个jar包没 ？
