Go To Definition fails with Definition not found

[lcsqlpete]

I don;t understand the above warning. I got here by opening the extension in vscode and clicking the Github releases and then selecting issues.

In a PHP class file, right-click on a function like this

$result = self::processRemovals_checkParameters()

and select Go To Definition.

Actual result: message "No definition found for processRemovals_checkParameters".

Expected result:The cursor jumps to the function.

Note that the function exists in the class file as private function and is executed correctly at run time.

Is this plugin still supported?
