7zip：错误，问题和疑问

Question

我正在尝试运行批处理文件，该文件仅提取带有7z.exe的.jar文件 这是我的代码：

set location=%cd%
set filename=%location%\outputfolder
set unzip=%location\resources

cd %unzip%
7z e -o%filename% -ir!*.jar -y "%filename%\*.zip"

但它提供了一个例外：error: incorrect command line因此我删除了-ir!*.jar，然后又出现了另一个错误：error: cannot use absolute pathnames for this command所以我将-o%filename%更改为-oC:\outputfolder它的工作原理!!!!!!（这是我现在的脚本）：

set location=%cd%
set filename=%location%\outputfolder
set unzip=%location\resources

cd %unzip%
7z e -oC:\outputfolder -y "%filename%\*.zip"

但我需要这些功能 如何解决？

Answer 1

用双引号试试，%cd%可能有空格：

7z e -o"%filename%" -i!*.jar -y "%filename%\*.zip"
