Description

When you have a Version structure with a version field the generated equals method do not working since fields are not accessed with this..

openapi-generator version

I'm using the docker image v7.0.2.

OpenAPI declaration file content or url

{
    "schemas": {
        "Version": {
            "type": "object",
            "properties": {
                "version": {"type": "string"}
            }
        }
    }
}

Generation Details

docker run \
	--rm \
	--volume "$${PWD}:/local" \
	openapitools/openapi-generator-cli:v7.2.0 \
	generate \
		--global-property models \
		--input-spec /local/openapi.json \
		--generator-name java-vertx-web \
		--output /local/backend/

Suggest a fix

Change generation to have this diff on generated output :

diff --git a/backend/.../model/Version.java b/backend/.../model/Version.java
index b3ef134..e889c27 100644
--- a/backend/.../model/Version.java
+++ b/backend/.../model/Version.java
@@ -30,11 +30,11 @@ public class Version   {
   @Override
   public boolean equals(Object o) {
     if (this == o) {
       return true;
     }
     if (o == null || getClass() != o.getClass()) {
       return false;
     }
     Version version = (Version) o;
-    return Objects.equals(version, version.version);
+    return Objects.equals(this.version, version.version);
   }

Reproduce the issue with the provided Docker generation command and inspect the generated backend/.../model/Version.java file. Compare the equals method with the suggested diff, then trace the Java Vert.x Web model-generation entry point that produces it. Done means the generated method accesses the current object's field with this.version and the reproduction no longer fails.
