universalArchiveOptions setting tar CLI command arguments: incorrect order (maybe)

[mackler]

I'm unsure whether or not I'm seeing a bug. I added this line to my build.sbt

universalArchiveOptions in (Universal, packageZipTarball) := Seq("--exclude", "*~")

and I got a new tar error, including (in part) the following output:

Running with tar --exclude *~ /tmp/sbt_726bf22d/myApp-0.1.tar myApp-0.1
tar: Must specify one of -c, -r, -t, -u, -x

It looks as if my custom tar option may need to come after the tar-file name rather than before. It might also be causing a -c switch to go missing, but that might be a default and unnecessary; I am unsure.

Or maybe I'm doing something wrong.

I guess your configuration is not correct. The options are used like this.

val cmd = Seq("tar") ++ options ++ Seq(tmptar.getAbsolutePath) ++ distdirs

The error message you are seeing also states what is missing. As you override the default configuration, which is

universalArchiveOptions in (Universal, packageZipTarball) := Seq("-pcvf")

the tar command isn't complete.
