webase中导入已经写入的合约，导出java项目的问题

[Wangxiujie2001]

系统：ubuntu22.04

zip version：
Copyright (c) 1990-2008 Info-ZIP - Type 'zip "-L"' for software license.
This is Zip 3.0 (July 5th 2008), by Info-ZIP.

Ubuntu20.04，zip版本也是3.0，导出的java项目可以解压

在webase中导入合约后，点击导出java项目，随后导出的压缩包无法成功打开
unzip 项目.zip后，出现如下错误：

Archive:  CarbonTrade.zip
  End-of-central-directory signature not found.  Either this file is not
  a zipfile, or it constitutes one disk of a multi-part archive.  In the
  latter case the central directory and zipfile comment will be found on
  the last disk(s) of this archive.
unzip:  cannot find zipfile directory in one of CarbonTrade.zip or
        CarbonTrade.zip.zip, and cannot find CarbonTrade.zip.ZIP, period.
