No node to visit provided for visitAnonymousClass

[adamculp]

• PHPMD version: 2.10.2snapshot202107221018
• PHP Version: 7.4.3
• Installation type: (phar file)
• Operating System / Distribution & Version: (Windows 10)

Current Behavior

When issuing the following command:

php phpmd.phar ./ng/backend xml codesize --exclude 'vendor' --reportfile 'phpmd_results.xml'

After about 20 seconds I receive the following message:

No node to visit provided for visitAnonymousClass

Also, the result file phpmd_results.xml is empty.

Expected Behavior

After some time, the phpmd_results.xml would contain the results.

Steps To Reproduce:

From within my project directory, use the following command to get phpmd:

$ wget -c https://phpmd.org/static/latest/phpmd.phar

Then issue the command above for phpmd to analyse the code.

Note: I get this same error when attempting to use PDepend, as well.

Regarding the message, it probably fails to parse an anonymous class. Please try to spot the occurrences of new class in your command, comment/uncomment them to see which one fails.

@kylekatarnls I confirmed there were 2 instances of new class, and both of them resulted in the same message. (commented out one at a time to confirm)

They both fit this pattern:

class MyClass
{
    public function myFunction()
    {
        $myParameter = new class($value) extends AnotherClass {

            public function __construct($someValue)
            {
                // do something
            }

            public function doSomething()
            {
                // do something
            }
        };
    }
}

Any other info I can provide?

[kylekatarnls]

Hello, when using:
$myParameter = new class... {...}
I get Unexpected token: }

I assumed the ; was missing and fixed it:
$myParameter = new class... {...};
Then it works just fine for me: phpmd_results.xml is generated with no error.

Are you able to create a 1-file project that reproduces this bug?

Thanks 🙏

Thanks @kylekatarnls, that was my typo. The original code does have semicolon. I've corrected above to add the semicolon. However, this next week I will re-test to see if this is still happening.
