Currently, when --output is used multiple times on the same directory, the underlying command which copies the output can fail with a misleading error message. Even if your regular expression matches a file in the target directory, you're presented with: "no files found within ./target matching the provided output regexp" If the "mv" command's stderr is printed, it shows: "mv: inter-device move failed: '/tmp/earthly/lib/rust/release' to 'target/release'; unable to remove target: Directory not empty" Since "mv" doesn't handle existing directories the way we may want here, let's use "cp -ruT" to overlay the files into the target directory (regardless of what's already present there) and then remove the temporary directory.
