ADDITIONAL SYSTEM INFORMATION :
I am using the "openjdk-17-jdk" package from Ubuntu on WSL2, and comparing it to the oracle jdk on windows.

A DESCRIPTION OF THE PROBLEM :

I believe I have uncovered a bug (or a disagreement?) in the usage of the jar command.

In the man page for jar on my system it is stated:

       -C DIR Changes the specified directory and includes the files specified at the end of the command line.

              jar [OPTION ...] [ [--release VERSION] [-C dir] files]

as well as in the documentation for oracle's jar:

       -C dir

              Temporarily changes directories to dir while processing the following inputfiles argument. Multiple -C dir inputfiles sets are allowed.
       [...]
              Temporarily changes directories (cd dir) during execution of the jar command while processing the following inputfiles argument. Its operation is intended to be similar to the -C option of the UNIX tar utility.

Yet whenever I specify a single -C in my Makefile I get the following error:

       jar cfe target/release.jar FutureTesting.Test -C target FutureTesting/Test.class FutureTesting/WebService.class
       FutureTesting/WebService.class : no such file or directory
       make: *** [Makefile:18: target/release.jar] Error 1

To workaround the issue I have to inconveniently use -C target multiple times:

       jar cfe target/release.jar FutureTesting.Test -C target FutureTesting/Test.class -C target FutureTesting/WebService.class




FREQUENCY : always
