Description

Hi when i am generating java client using openapi generator enum name is not generating properly. It is removing TEST_ with name

openapi.yaml

fileType:
type: string
description: File type indicates test file or test run result
enum:
- TEST_PACKAGE
- TEST_RESULT_FILE

Actual generated java client is

@JsonAdapter(FileTypeEnum.Adapter.class)
public enum FileTypeEnum {
PACKAGE("TEST_PACKAGE"),

RESULT_FILE("TEST_RESULT_FILE");

EXPECTATION:

public enum FileTypeEnum {
TEST_PACKAGE("package"),

Suggest a fix

Start with the supplied openapi.yaml and pom.xml generator configuration, run the Java client generator, and inspect the generated FileTypeEnum. Trace how enum names are derived in the Java generator or its templates; done means TEST_PACKAGE and TEST_RESULT_FILE remain the generated enum constants with the expected serialized values.
