【问题描述】：

我正在使用 apache httpclient，但它找不到

import org.apache.http.impl.client.HttpClients;

在 google 上快速搜索将我带到 org.apache.http.legacy，但我找不到 org.apache.http.legacy 的组、工件和修订版

它们是什么以及如何将该依赖项添加到我的 build.sbt 文件中？总堆栈跟踪是

我的代码是

HttpClient httpclient = HttpClients.createDefault();
HttpPost httppost = new HttpPost(URL);
httppost.addHeader(API_KEY, X_API_KEY);
// Request parameters and other properties.
List<NameValuePair> params = new ArrayList<NameValuePair>(2);
params.add(new BasicNameValuePair(GRANT_TYPE, "password"));
params.add(new BasicNameValuePair(USERNAME, _USERNAME));
params.add(new BasicNameValuePair(PASSWORD, O_PASSWORD));
httppost.setEntity(new UrlEncodedFormEntity(params, "UTF-8"));

HttpResponse response = httpclient.execute(httppost);
HttpEntity entity = response.getEntity();

if (entity != null) {
    InputStream instream = entity.getContent();
    try {
        System.out.println(instream);
    } finally {
        instream.close();
    }
}

【解决方案1】：

在 google 上快速搜索将我带到 org.apache.http.legacy

不确定您搜索的是什么，但我知道这是用于 Android 项目的常用依赖项，而不仅仅是任何常规 SBT 项目

您可以在MvnRespository找到您要查找的内容

libraryDependencies += "org.apache.httpcomponents" % "httpclient" % "4.5.2"
