Comprehensibility Bug introduced by
It seems like you call parent on a different method (setWorkingDirectory() instead of setWorkingDirectoryLocal()). Are you sure this is correct? If so, you might want to change this to $this->setWorkingDirectory().

This check looks for a call to a parent method whose name is different than the method from which it is called.

Consider the following code:

class Daddy
{
    protected function getFirstName()
    {
        return "Eidur";
    }

    protected function getSurName()
    {
        return "Gudjohnsen";
    }
}

class Son
{
    public function getFirstName()
    {
        return parent::getSurname();
    }
}

The getFirstName() method in the Son calls the wrong method in the parent class.

Bug Best Practice introduced by
The expression $this->getWorkingDirectory() of type string|null is loosely compared to true; this is ambiguous if the string can be empty. You might want to explicitly use !== null instead.

In PHP, under loose comparison (like ==, or !=, or switch conditions), values of different types might be equal.

For string values, the empty string '' is a special case, in particular the following results might be unexpected:

''   == false // true
''   == null  // true
'ab' == false // false
'ab' == null  // false

// It is often better to use strict comparison
'' === false // false
'' === null  // false

Unused Code introduced by
$cmd is not used, you could remove the assignment.

This check looks for variable assignements that are either overwritten by other assignments or where the variable is not used subsequently.

$myVar = 'Value';
$higher = false;

if (rand(1, 6) > 3) {
    $higher = true;
} else {
    $higher = false;
}

Both the $myVar assignment in line 1 and the $higher assignment in line 2 are dead. The first because $myVar is never used and the second because $higher is always overwritten for every possible time line.

Bug introduced by
There is no parameter named $siteAlias. Was it maybe removed?

This check looks for PHPDoc comments describing methods or function parameters that do not exist on the corresponding method or function.

Consider the following example. The parameter $italy is not defined by the method finale(...).

/**
 * @param array $germany
 * @param array $island
 * @param array $italy
 */
function finale($germany, $island) {
    return "2:1";
}

The most likely cause is that the parameter was removed, but the annotation was not.
