尝试使用API时出错。nosuchfielderror：实例

Question

Exception in thread "main" java.lang.NoSuchFieldError: INSTANCE
    at org.apache.http.conn.ssl.SSLConnectionSocketFactory.<clinit>(SSLConnectionSocketFactory.java:144)

    at SmartsheetConnection.main(SmartsheetConnection.java:13)

import com.smartsheet.api.*;
import com.smartsheet.api.models.*;
import com.smartsheet.api.models.enums.*;
import com.smartsheet.api.oauth.*;

public class SmartsheetConnection {
    public static void main(String[] args) throws SmartsheetException {
        // Set the access token.
        Token token = new Token();
        token.setAccessToken("foo");
        Smartsheet smartsheet = new SmartsheetBuilder().setAccessToken(token.getAccessToken()).build();
    }
}

@Deprecated
    public static final X509HostnameVerifier ALLOW_ALL_HOSTNAME_VERIFIER
        = AllowAllHostnameVerifier.INSTANCE; 

但我不知道该怎么做。我正在使用maven来获取依赖项。它是否与Apache HttpComponents的版本有关？

下面是pom.xml

    <build>
        <sourceDirectory>src</sourceDirectory>
        <plugins>
            <plugin>
                <artifactId>maven-compiler-plugin</artifactId>

其他关于此错误的帖子似乎表明，这通常是由httpcoreJAR的版本冲突造成的。即类路径上httpcore的旧版本。
