Maker Bundle fails to create ManyToOne relation

(Creating new issue because can't reopen existing one.)

Here is the console log:

>php bin/console make:entity

 Class name of the entity to create or update (e.g. GentleChef):
 > TransportCostRule

 Your entity already exists! So let's add some new fields!

 New property name (press <return> to stop adding fields):
 > settingEntity

 Field type (enter ? to see all types) [string]:
 > relation

 What class should this entity be related to?:
 > Setting

What type of relationship is this?
 ------------ --------------------------------------------------------------------------------
  Type         Description

 ------------ --------------------------------------------------------------------------------
  ManyToOne    Each TransportCostRule relates to (has) one Setting.

               Each Setting can relate to (can have) many TransportCostRule objects


  OneToMany    Each TransportCostRule can relate to (can have) many Setting objects.
               Each Setting relates to (has) one TransportCostRule



  ManyToMany   Each TransportCostRule can relate to (can have) many Setting objects.
               Each Setting can also relate to (can also have) many TransportCostRule objects


  OneToOne     Each TransportCostRule relates to (has) exactly one Setting.

               Each Setting also relates to (has) exactly one TransportCostRule.

 ------------ --------------------------------------------------------------------------------

 Relation type? [ManyToOne, OneToMany, ManyToMany, OneToOne]:
 > ManyToOne

 Is the TransportCostRule.settingEntity property allowed to be null (nullable)? (yes/no) [yes]:
 > no

 Do you want to add a new property to Setting so that you can access/update TransportCostRule objects from it - e.g. $setting->getTransportCostRules()? (yes/no) [yes]:
 >

 A new property will also be added to the Setting class so that you can access the related TransportCostRule objects from it.

 New field name inside Setting [transportCostRules]:
 >

 Do you want to activate orphanRemoval on your relationship?
 A TransportCostRule is "orphaned" when it is removed from its related Setting.
 e.g. $setting->removeTransportCostRule($transportCostRule)

 NOTE: If a TransportCostRule may *change* from one Setting to another, answer "no".

 Do you want to automatically delete orphaned App\Entity\TransportCostRule objects (orphanRemoval)? (yes/no) [no]:
 > yes

PHP 7.2.10

Start by reproducing the reported make:entity ManyToOne workflow with the linked entity examples and inspect the failure reported at ParserAbstract.php line 315. Compare the generated entity output with the PHP 7.2.10 syntax error, then verify that creating the relation with orphanRemoval completes without a parse error.
