I have been able to pinpoint this to the usage of

"?../*/**"

in the visibility ruleset; the parser doesn't seem to handle the double dots

..

. Validating dependencies on targets anywhere else in the repo (except the root) or without using double dot in the pattern doesn't cause the error to be thrown. Pants version 2.16 / 2.17 / 2.18 OS Not OS specific Additional info If it's an implementation constraint, it would be helpful to know how to work around this. pantsbuild/pants
