com.lark.oapi.service.directory找不到

组织架构-员工管理-批量获取员工列表的API Java SDK的示例中com.lark.oapi.service.directory.v1.model.; 找不到，请问该如何引入此包呢？
示例代码如下：
`package com.lark.oapi.sample.apiall.directoryv1;
import com.google.gson.JsonParser;
import com.lark.oapi.Client;
import com.lark.oapi.core.utils.Jsons;
import com.lark.oapi.service.directory.v1.model.;
import java.util.HashMap;
import com.lark.oapi.core.request.RequestOptions;

// SDK 使用文档：https://open.feishu.cn/document/uAjLw4CM/ukTMukTMukTM/server-side-sdk/java-sdk-guide/preparations
// 复制该 Demo 后, 需要将 "YOUR_APP_ID", "YOUR_APP_SECRET" 替换为自己应用的 APP_ID, APP_SECRET.
// 以下示例代码默认根据文档示例值填充，如果存在代码问题，请在 API 调试台填上相关必要参数后再复制代码使用
public class FilterEmployeeSample {

public static void main(String arg[]) throws Exception {
	// 构建client
	Client client = Client.newBuilder("YOUR_APP_ID", "YOUR_APP_SECRET").build();

	// 创建请求对象
	FilterEmployeeReq req = FilterEmployeeReq.newBuilder()
		.employeeIdType("")
		.departmentIdType("")
		.filterEmployeeReqBody(FilterEmployeeReqBody.newBuilder()
			.filter()
			.requiredFields()
			.pageRequest()
			.build())
		.build();

	// 发起请求
	FilterEmployeeResp resp = client.directory().v1().employee().filter(req, RequestOptions.newBuilder()
		.userAccessToken("")
		.build());

	// 处理服务端错误
	if(!resp.success()) {
		System.out.println(String.format("code:%s,msg:%s,reqId:%s, resp:%s",
			resp.getCode(), resp.getMsg(), resp.getRequestId(), Jsons.createGSON(true, false).toJson(JsonParser.parseString(new String(resp.getRawResponse().getBody(), StandardCharsets.UTF_8)))));
		return;
	}

	// 业务数据处理
	System.out.println(Jsons.DEFAULT.toJson(resp.getData()));
}

}`

Start with the Java SDK preparations guide linked in the issue and inspect how the example obtains com.lark.oapi.service.directory.v1.model.*. Confirm the dependency or generated package used by the FilterEmployeeSample example, then verify that the sample imports and builds successfully.
