[BUG] Xml deserializer not generated

[amazoyer]

Hello,

When using a client with openapi version 5.4.0 and the java generator, I get the following exception:
com.test.nifi.invoker.ApiException: Deserialization for content type 'application/xml' not supported for type 'com.test.nifi.api.ProcessGroupsApi$31@36d582cb'

When I did into the generated code, I can see that the xml deserialization is not implemented:

public <T> T deserialize(HttpResponse response, TypeReference<T> valueType) throws ApiException, IOException { if (valueType == null) { return null; } HttpEntity entity = response.getEntity(); Type valueRawType = valueType.getType(); if (valueRawType.equals(byte[].class)) { return (T) EntityUtils.toByteArray(entity); } else if (valueRawType.equals(File.class)) { return (T) downloadFileFromResponse(response); } String mimeType = getResponseMimeType(response); if (mimeType == null || isJsonMime(mimeType)) { // Assume json if no mime type return objectMapper.readValue(entity.getContent(), valueType); } else { throw new ApiException( "Deserialization for content type '" + mimeType + "' not supported for type '" + valueType + "'", response.getStatusLine().getStatusCode(), responseHeaders, EntityUtils.toString(entity) ); } }

Even though I think I correctly activated the xml generation option as we can see in the maven debug log during generation:
[DEBUG] (f) skipValidateSpec = true [DEBUG] (f) typeMappings = [] [DEBUG] (f) verbose = false [DEBUG] (f) withXml = true [DEBUG] -- end configuration --
Any idea what can go wrong?

Thank you,

Aurelien

@amazoyer have you generated using withXml=true set as additional-properties, not global-property?
