Try this Regex:

modules\/(?![^\/]*RelationModule)[^\/]*\/graphql-schema

Click for Demo

See the JAVA code here

Explanation:

  • modules\/ - matches modules/ literally
  • (?![^\/]*RelationModule) - negative lookahead to check if the the text RelationModule is present anywhere before the occurrence of next / in the directory
  • [^\/]* - matches 0+ occurrences of any character except /
  • \/graphql-schema - matches /graphql-schema literally

If you do not want RelationModule anywhere in the directory, you can simply use ^(?!.*RelationModule).+$
