Fixed version (ground truth):

    String relativePath=null;
    URI parentURI=ResourceManager.getPatternFolder().getLocationURI();
    relativePath=parentURI.relativize(file.getParent().getLocationURI()).toString();
    relativePath=relativePath.substring(relativePath.indexOf('/') + 1);
    if (EResourceConstant.PATTERN_REGEX.getName().equals(relativePath) || EResourceConstant.PATTERN_SQL.getName().equals(relativePath)) {
      relativePath=PluginConstant.EMPTY_STRING;
    }
    patternMap.put(PatternToExcelEnum.Label,pattern.getName());

    patternMap.put(PatternToExcelEnum.Description,MetadataHelper.getDescription(pattern));
