This is user error caused by an incorrect regular expression. In the user's configuration: `<packagingExcludes>%regex[WEB-INF/lib/[email\\-library\\-|web\\-services\\-library\\-].*\\.jar]</packagingExcludes>` The user enclosed their alternation (`|`) inside square brackets `[...]`. In regular expressions, square brackets define a character class, which matches any single character present in the set. Therefore, `[email\-library\-|web\-services\-library\-]` will only match exactly one character from that set (such as 'e', 'm', 'a', '-', '|', 'w', etc.), rather than evaluating the logical OR between the two full strings "email-library-" and "web-services-library-". To apply an alternation to multi-character strings, the user must use parentheses `()` for grouping. The correct syntax is: `<packagingExcludes>%regex[WEB-INF/lib/(email\-library\-|web\-services\-library\-).*\.jar]</packagingExcludes>` A commenter on the issue (Cedric HENRY) correctly identified this syntax error. The plugin itself is functioning as designed. -- This is an automated message from the Apache Git Service.
