无法解析符号：'HttpClient'，即使在添加依赖项后也是如此

Question

我尝试添加Apache commons libs的各种依赖项。

我尝试了httpClient，httpCore和许多不同的版本。也可以从外部罐子和maven建议。

我在gradle：

中结束了这一点

compile 'org.apache.httpcomponents:httpcore:4.4.1'
compile 'org.apache.httpcomponents:httpclient:4.3.5'

它仍然给我Cannot resolve HttpClient和Cannot resolve HttpPost等。

它不允许我导入类。

执行HTTP帖子的代码：

 // Create a new HttpClient and Post Header
            HttpClient httpclient = new DefaultHttpClient();
            HttpPost httppost = new HttpPost("http://fdsgsfdgs);

            try {
                // Add your data
                List<NameValuePair> nameValuePairs = new ArrayList<>(2);
                nameValuePairs.add(new BasicNameValuePair("id", null));
                nameValuePairs.add(new BasicNameValuePair("name", "TestFromAppSpell"));
                nameValuePairs.add(new BasicNameValuePair("damage", "12345"));
                nameValuePairs.add(new BasicNameValuePair("heal", "50"));
                nameValuePairs.add(new BasicNameValuePair("description", "Testtestest"));
                nameValuePairs.add(new BasicNameValuePair("coordinates", coordinates));
                httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

                // Execute HTTP Post Request
                HttpResponse response = httpclient.execute(httppost);
                System.out.println("Http post done!");
            } catch (ClientProtocolException e) {
                // TODO Auto-generated catch block
            } catch (IOException e) {
                // TODO Auto-generated catch block
            }

Gradle文件：

buildscript {
    repositories {
        jcenter()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:1.2.3'
    }
}

apply plugin: 'com.android.application'

repositories {
    jcenter()
}

dependencies {
    compile 'com.android.support:support-v4:23.0.0'
    compile 'com.android.support:gridlayout-v7:23.0.0'
    compile 'com.android.support:cardview-v7:23.0.0'
    compile 'org.apache.httpcomponents:httpcore:4.4.1'
    compile 'org.apache.httpcomponents:httpclient:4.3.5'
}

dependencies {
    compile 'com.android.support:appcompat-v7:+'
    compile fileTree(dir: 'libs', include: ['*.jar'])
}

// The sample build uses multiple directories to
// keep boilerplate and common code separate from
// the main sample code.
List<String> dirs = [
    'main',     // main sample code; look here for the interesting stuff.
    'common',   // components that are reused by multiple samples
    'template'] // boilerplate code that is generated by the sample template process

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.0"

    defaultConfig {
        minSdkVersion 11
        targetSdkVersion 23
    }

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_7
        targetCompatibility JavaVersion.VERSION_1_7
    }

    sourceSets {
        main {
            dirs.each { dir ->
                java.srcDirs "src/${dir}/java"
                res.srcDirs "src/${dir}/res"
            }
        }
        androidTest.setRoot('tests')
        androidTest.java.srcDirs = ['tests/src']

    }

}

添加最后一个lib并且应该可以工作。它的作品对我来说
