I have a build system with a command line driven batch file that uses
jar (from Java JDK) on a Windows machine to make a zip file like this ...
jar cf c:\target\Application-1.5.zip -C Application-1.5/ .
It "zips" up everything in the
Application-1.5 directory into zip file
jar because there's no
zip command at the command line on Windows.
When I download the zip file on a Windows 10 machine, Windows extracts the zip fine.
However, when I download the zip file on my MacBook (Catalina), and double-click on the zip file, the Mac won't unzip the file ... it says ... "Unable to expand "Application-1.5.zip". It is an unsupported format.
Also ... when I use the jar command on the Mac to unzip it like this
jar -xf ./Application-1.5.zip it works, so the file is "valid" but Mac's built-in unzipper doesn't like it.
What do I do to make a zip file that Mac will like?
