[ERROR] 2021-05-08 23:21:19 As a workaround you can disable these inspections in yml config: [KDOC_CONTAINS_DATE_OR_AUTHOR, KDOC_EMPTY_KDOC, KDOC_NEWLINES_BEFORE_BASIC_TAGS, KDOC_NO_DE
PRECATED_TAG, KDOC_NO_EMPTY_TAGS, KDOC_NO_NEWLINES_BETWEEN_BASIC_TAGS, KDOC_NO_NEWLINE_AFTER_SPECIAL_TAGS, KDOC_WRONG_SPACES_AFTER_TAG, KDOC_WRONG_TAGS_ORDER]

As a WA, you can remove an empty line before 'for example', so that tag's body doesn't have empty lines.
