You can't do that. Archive rules work ONLY with real archives (libX.a
files), created with the UNIX ar(1) utility.
GNU make has C code that knows how to parse an ar archive file and
examine its contents: this is the only way make's archive capability can
work (it must be able to obtain a table of contents that includes
timestamps). That code can't parse any kind of file, just ar files. In
particular jar files are ZIP files, which are totally different.
