[JAXRS-SPEC] Enum values are generating """, "D;", imports are being written inside class declaration #3856
Description
Description
I wanted to generate API Definition with the swagger-codegen-maven-plugin, for jaxrs-spec so that I receive only the models and basic API implementations (i.e., no factories). For all models that have an enum however, it produces uncompilable source code.
Swagger-codegen version
The latest stable build, 2.2.1, although I have also tried 2.2.2-SNAPSHOT but it has not made a difference.

mvn clean io.swagger:swagger-codegen-maven-plugin:generate with the following plugin entry in the pom.xml:

Steps to reproduce
Attempt to generate server stubs using the model definition above.
The generated source code then looks similar to the following:
package com.product.rest.model;
import java.time.OffsetDateTime;
import io.swagger.annotations.*;
import java.util.Objects;
public class T {
private Double amount = null;
private String currency = null;
import javax.xml.bind.annotation.XmlEnum;
import javax.xml.bind.annotation.XmlType;
@XmlType(name="T")
@XmlEnum
public enum T {
{values=[initial], enumVars=[{name=INITIAL, value="initial"}]},
public String value() {
return name();
}
public static T fromValue(String v) {
return valueOf(v);
}
}
private StateEnum state = null;
...
(Ordering of imports is as-generated)

A similar issue was reported for JaxRS-CXF in issue #3735 which was fixed a few weeks ago.
Suggest a Fix
The problem seems to be the mustache template that is used for the JaxRS-SPEC code generation. I attempted a fix but as I am wholly unfamiliar with mustache, did not get very far.
