Maybe I'm thick, but I still don't understand the need for the versioned ones
or exactly what smarts you're talking about.
find_jar in java-functions falls back to unversioned jar if it can't find the
requested versioned jar [0], so not even things that do "find-jar foo-1.2.3"
would break if foo-1.2.3.jar would not be there but foo.jar would.
Because installing multiple packages that own the same versionless symlink
pointing to different files would result in a conflict, we can't really do it
anyway. And if a package requires a specific version of some other, it'd
need to have a versioned dependency in place in all cases - using the version
in find-jar and friends' arguments does not seem to add any value to me.
Actually on the contrary: it just adds one more thing that can break.
What am I still missing? If something, could you provide specific examples?
[0] Well, except that it doesn't, a sed in find_jar is not working as clearly
intended, this needs to be fixed in jpackage-utils:
$ echo foo-1.0.0 | sed 's+-[\.[:digit:]]\+$++g'
foo-1.0.0
But:
$ echo foo-1.0.0 | sed 's/-[\.[:digit:]]\+$//g'
foo
