How to avoid generating methods for non-getters with the maven plugin?

[takanuva15]

Hi, I am autogenerating a bunch of schemas for my model classes using the maven plugin. I am using lombok to add hashCode and equals methods to my model classes.

I have a class like this:

import lombok.Data;

@Data
public class Dog {
	private int barkVolume;

	public String getBreed() {
		return <calculated-stuff>;
	}
}

When I run the maven plugin with these options:

<options>
  <enabled>
    <option>NONSTATIC_NONVOID_NONGETTER_METHODS</option>
    <option>FIELDS_DERIVED_FROM_ARGUMENTFREE_METHODS</option>
  </enabled>
</options>

...this is the schema that's generated:

properties:
  barkVolume:
    type: integer
  breed:
    type: string
  canEqual(Object):
    type: boolean
  equals(Object):
    type: boolean
  hashCode():
    type: integer
  toString():
    type: string

I'm only interested in generating properties for methods that begin with get...() that take no arguments. How do I get rid of the other stuff that the schema generator is adding in there beyond breed?

(I tested this out on the same MVE repo that I mentioned in my other issue #393.

Hi @takanuva15,

The easiest way would be adding this to your GeneralConfigModule class:

builder.forMethods()
        .withIgnoreCheck(method -> method.getSchemaPropertyName().endsWith(")"));

The Option.FIELDS_DERIVED_FROM_ARGUMENTFREE_METHODS will discard the appended parentheses and "get"/"is" prefix if the method is deemed eligible (i.e., matches get...() or is...() or was explicitly set to another name). If the method's designated name in the schema would still have those parentheses, you can ignore that method again this way.
No need to duplicate the checks being performed in the MethodScope class.

The generated schema looks like this then:

---
$schema: https://json-schema.org/draft/2020-12/schema
type: object
properties:
  barkVolume:
    type: integer
  breed:
    type: string
