我有一个Maven Java项目,它使用Mashape Unirest将HTTP请求发送到其他URL.我目前正在编写一个使用Unirest发送普通HTTP请求的集成测试(使用TestNG).当我通过Maven(通过Failsafe插件)运行集成测试时,请求成功发送.但是,当我尝试通过Eclipse运行集成测试时,我继续收到以下错误:
FAILED: getCurrentTimeTest

我还能够使用基本的Java应用程序脚本重现此错误.
我确保我在pom.xml文件中使用的依赖项是最新的和最好的,如下所示:
<dependency>
<groupId>com.mashape.unirest</groupId>
<artifactId>unirest-java</artifactId>
<version>1.3.5</version>

我还检查了源代码 …
我正在使用Apache的HttpClient组件来完成以下简单程序,我看到以下异常:

try {
HttpResponse response = client.execute(request);
System.out.println(response.getStatusLine());
} catch (Exception e) {
e.printStackTrace();
}
}
}
我在用
有任何想法吗？
美好的一天!
我需要帮助!
