（已解决）装入归档文件时出现了一个错误，End-of-central-directory signature not found.

$ unzip 2.4.10.zip
Archive:  2.4.10.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 2.4.10.zip or
        2.4.10.zip.zip, and cannot find 2.4.10.zip.ZIP, period.

尝试过直接提取到此处和用unzip命令解压压缩包，均失败。
可尝试用jar xvf filename.zip来进行解压
若提示jar:Command not found，则ubuntun下使用：sudo apt-get install -f jar,
运行结果如下图所示。

$ jar xvf 2.4.10.zip
