我想实现这个代码

public void testGetExchangeRate() throws Exception
{
    ECKey key = KeyUtils.createEcKey();

    String clientName = "server 1";
    BitPay bitpay = new BitPay(key, clientName);

    if (!bitpay.clientIsAuthorized(BitPay.FACADE_MERCHANT))
    {
        // Get Merchant facade authorization code
        String pairingCode = bitpay.requestClientAuthorization(
            BitPay.FACADE_MERCHANT);

        // Signal the device operator that this client needs to
        // be paired with a merchant account.
        System.out.print("Info: Pair this client with your merchant account using the pairing Code: " + pairingCode);
        throw new BitPayException("Error:client is not authorized for Merchant facade");
    } …

我试图在 Eclipse 的 maven 项目中作为 Java 应用程序运行，但出现以下运行时错误。错误如下所示。

线程“main”中的异常 java.lang.NoClassDefFoundError: org/apache/http/ConnectionReuseStrategy at com.wang.testMaven.App.main(App.java:16) 由：java.lang.ClassNotFoundException: org.apache.http .ConnectionReuseStrategy at java.net.URLClassLoader.findClass(URLClassLoader.java:381) at java.lang.ClassLoader.loadClass(ClassLoader.java:424) at java.lang.ClassLoader.loadClass(ClassLoader.java:357)

我的代码如下所示

public class App 
{
    public static void main( String[] args )
    {
        System.out.println( "Hello World!" );
        HttpClient httpClient = HttpClientBuilder.create().build();
        System.out.println( "Hello World!" );

    }
}

我的 pom.xml 如下所示
