Description: ------------ When using the --report-file option with a relative path, and the target file does not already exist, I get a file_put_contents() PHP Warning failure. If I use an absolute path, the file will be created successfully. If I use a relative path, I *must* create the file myself before running phpcs. Test script: --------------- Files: - relative/file1.php - relative/file2.php - relative/path/to/ Run from parent dir of relative/: phpcs --report-file=relative/path/to/checkstyle.xml --report=checkstyle --ignore=relative/path relative/ Expected result: ---------------- relative/path/to/checkstyle.xml file to be created Actual result: -------------- PHP Warning: file_put_contents(relative/path/to/checkstyle.xml): failed to open stream: No such file or directory in /absolute/path/to/PHP/CodeSniffer/Reporting.php on line 102 PHP Stack trace: PHP 1. {main}() /absolute/path/to/phpcs:0 PHP 2.
