PHPDocumentor `-d` results in empty documentation, but `-f` is working as expected

• I have my PHP codes in folder called src.
• That src folder is in folder called lib.
• My documentation will be in lib/docs.
• So, both src and lib are located in the same folder.

Now when I am generating the documentation:

• I tried: php phpDocumentor.phar -f ../pdk/Something.php and it works fine!
• I tried: php phpDocumentor.phar -d ../pdk but it does not work, the documentation is generated but it is empty. Not even Something.php got its documentations generated.

It's a bug -- https://github.com/phpDocumentor/phpDocumentor2/issues/1930

Should be solved in next release.

Workaround is to execute phpdoc in a directory so that the -d arg is -d .
