why remove initialization customScalars configured by generatePojoConf on 2.x version?

[minkik715]

hi guys!
Is there some reason on removing initialization customScalars configured at generatePojoConf on 2.x version?

1.18.6 Version
com.graphql_java_generator.plugin.generate_code
GenerateCodeDocumentParser 171 line

logger.debug("Storing custom scalar's implementations [START]");
if (configuration.getCustomScalars() != null) {
	for (CustomScalarDefinition customScalarDef : configuration.getCustomScalars()) {
		CustomScalarType type = new CustomScalarType(customScalarDef, configuration, this);
		getCustomScalars().add(type);
		getTypes().put(type.getName(), type);
	}
}
logger.debug("Storing custom scalar's implementations [END]");

On my project scalars are declared by external libraries which i made(common interface),
so before 2.x version, there are no problems,
but after 2.x version when i generatePojo , throw error "the type named 'Long' could not be found"

i hope to be change like this

@Override
	protected void initScalarTypes(Class<?> notUsed) {
		// Let's load the standard Scalar types
		GenerateCodeCommonConfiguration generateConfiguration = getConfiguration();
		if (generateConfiguration.getMode().equals(PluginMode.server)) {
			try {
				super.initScalarTypes(
						Class.forName(((GenerateServerCodeConfiguration) this.configuration).getJavaTypeForIDType()));
			} catch (ClassNotFoundException e) {
				throw new RuntimeException(e.getMessage(), e);
			}
		} else {
			// In client mode, ID type is managed as a String
			super.initScalarTypes(String.class);
		}

		logger.debug("Storing custom scalar's implementations [START]");
		if (generateConfiguration.getCustomScalars() != null) {
			for (CustomScalarDefinition customScalarDef : generateConfiguration.getCustomScalars()) {
				CustomScalarType type = new CustomScalarType(customScalarDef.getGraphQLTypeName(), customScalarDef, generateConfiguration, this);
				getCustomScalars().add(type);
				getTypes().put(type.getName(), type);
			}
		}
		logger.debug("Storing custom scalar's implementations [END]");
	}

if is not possible
is there some way to add customscalars which are configured on pojoGenerateConf?
