提问于 2014-12-03 04:06:18
我在Android应用程序中使用来自Mashape的API。Mashape建议使用Unirest库。我已经包含了unirest链接上提到的依赖项：http://unirest.io/java
我的亲信：
compile fileTree(dir: 'libs', include: ['*.jar'])
compile group:'com.mashape.unirest', name:'unirest-java', version:'1.3.26'
compile group:'org.apache.httpcomponents', name:'httpcore', version:'4.3.3'
compile group:'org.apache.httpcomponents', name:'httpclient', version:'4.3.6'
compile group:'org.apache.httpcomponents', name:'httpasyncclient', version:'4.0.2'
compile group:'org.apache.httpcomponents', name:'httpmime', version:'4.3.5'
compile group:'org.json', name:'json', version:'20141113'
compile 'com.android.support:appcompat-v7:21.0.+'当我制作一个HTTPRequest时，我仍然会得到这个错误：
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/http/conn/HttpClientConnectionManager

... 5 more我的java代码很简单：
HttpResponse<JsonNode> response = Unirest.get("https://testlink/all")
.header("X-Mashape-Key", TEST_KEY)
.asJson();你能帮我解决这个问题吗？谢谢你的帮忙!
更新:根据的建议，我将httpclient更改为httpclient-android。我的依赖关系现在如下所示：
compile fileTree(dir: 'libs', include: ['*.jar'])
compile group:'com.mashape.unirest', name:'unirest-java', version:'1.3.26'
compile group:'org.apache.httpcomponents', name:'httpclient-android', version:'4.3.5'

compile group:'org.apache.httpcomponents', name:'httpcore-nio', version:'4.3.3'
compile group:'org.apache.httpcomponents', name:'httpasyncclient', version:'4.0.2'
compile group:'org.apache.httpcomponents', name:'httpmime', version:'4.3.5'
compile group:'org.json', name:'json', version:'20141113'
compile 'com.android.support:appcompat-v7:21.0.0'在重新构建项目并运行它之后，我得到以下错误：

项目中没有用于跟踪类的类文件。
org/apache/http/conn/HttpClientConnectionManager因此，请在项目库中添加jar文件，您可以从下面的链接中下载此jar文件。

转到Project/Properties/Java构建路径/订单和导出--确保在Android依赖项和支持库前面进行检查，如果您使用它的话。
标记所有复选框，单击“应用”并清除项目。
