Reset to default

Edit the isBracedNamespace method in the setup/src/Magento/Setup/Module/Di/Code/Reader/FileClassScanner.php file to replace the following code:

throw new InvalidFileException('Namespace not defined properly');

with

throw new InvalidFileException('Namespace not defined properly. File name: ' . $this->filename);

And then recompile the code, it will print the file name related to this error, then you can easily resolve the issue.

  • thanks for your reply , I get to know file name , can we do further more to get line no of error in a file ? Commented Jun 28, 2023 at 3:48
  • @AmitDwivedi You're welcome. You can add this code if (is_array($token)) { echo PHP_EOL, "Line {$token[2]}: ", PHP_EOL; } before switch ($token[0]) { to print the line. As you have resolved your issue, could you please share with us the root cause of your issue? Commented Jun 28, 2023 at 7:33

    The Root cause as I observed is , I defined a Constant named "NAMESPACE" inside a Api interface file, I resolved it by changing the name of the constant. Commented Jun 28, 2023 at 14:55
  • Cool, thanks for sharing @AmitDwivedi Commented Jun 28, 2023 at 15:07
