However, the negative lookback/lookahead are not supported for security reasons, which prevents more complex rules like: - prohibit all `jar` files except if they are in the `resources1 directory ### Further details For example, no way to implement: ``` ^(?!(?:.*\/)?src\/test\/resources(?:\/|$))(?!.*gradle-wrapper\.jar$).*\.(?:jar|exe|a|ar|cpio|shar|iso|LBR|lbr|mar|sbx|tar|bz2|F|gz|lz|lzma|lzo|rz|sfark|sz|xz|z|Z|7z|s7z|ace|afa|alz|apk|arc|arj|b1|ba|bh|cab|car|cfs|cpt|dar|dd|dgc|dmg|ear|gca|ha|hki|ice|kgb|lzh|lha|lzx|pak|partimg|paq6|paq7|paq8|pea|pim|pit|qda|rar|rk|sda|sea|sen|sfx|shk|sit|sitx|sqx|tar.gz|tgz|tar.Z|tar.bz2|tbz2|tar.lzma|tlz|uc|uc0|uc2|ucn|ur2|ue2|uca|uha|war|wim|xar|xp3|yz1|zip|zipx|zoo|zpaq|zz|dll)$ ``` ### Proposal Add a new push rule to bypass the **Prohibited filenames** push rule: > **Prohibited filename exemptions** > Prohibited filenames that match this regular expression will be exempted and may be pushed. If this field is empty no filenames will be exempted. ### Links / references
