The type Swoole\Process was not found. Maybe you did not declare it correctly or list all dependencies?
                                                                                                

                    
                                            

                            

                            

                                
                                    
                                
                            


                            
The issue could also be caused by a filter entry in the build configuration.
If the path has been excluded in your configuration, e.g. excluded_paths: ["lib/*"],
you can move it to the dependency path list as follows:


filter:
    dependency_paths: ["lib/*"]

This check compares calls to functions or methods with their respective definitions.
If the call has less arguments than are defined, it raises an issue.


If a function is defined several times with a different number of parameters, the
check may pick up the wrong definition and report false positives. One codebase
where this has been known to happen is Wordpress. Please note the @ignore annotation hint above.
