Use `system "foo", "bar"` instead of `system "foo bar"`. Also applies to
`Utils.popen_read` and `Utils.popen_write` commands. RuboCop can
automatically fix these problems.
Empty resources are allowed to exist under the following form:
resource "filelock" do
on_linux do
url "6ee2168387/filelock-3.0.12.tar.gz"
sha256 "18d82244ee114f543149c66a6e0c14e9c4f8a1044b5cdaadd0f82159d6a6ff59"
end
end
In this case (or for the on_macos only resource case), just ignore the resource block.

When running Utils.popen (or similar popen command), having a line like
"SHELL=bash ..." doesn't work properly. Instead, use:
`Utils.popen({ "SHELL" => "bash" }, "...")`
