Question

我在java中使用Twilio SDK来解决java问题。我尝试使用2个不同版本的Twilio库，但我有两个不同的错误：

对于[twilio-java-sdk-6.3.0-jar-with-dependencies.jar]，我收到了：

Exception in thread "main" java.lang.NoSuchMethodError: org.apache.http.impl.conn.DefaultClientConnectionOperator.<init>(Lorg/apache/http/conn/scheme/SchemeRegistry;Lorg/apache/http/conn/DnsResolver;)V

对于[twilio-7.9.1-jar-with-dependencies.jar]，我收到了：

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

at iristk.app.bankAsst.Watson.sendMsg(Watson.java:82)

2错误是什么意思？并且，如果可能的话，如何解决它们？

谢谢

您的应用程序似乎有另一个版本的httpclient＆amp; httpcore与wilio-java-sdk不兼容。请检查您的pom.xml并删除httpclient＆amp; httpcore的依赖项。如果你在pom.xml中看不到httpclient＆amp; httpcore的依赖关系，请运行“mvn dependency：tree”来查找包含httpclient＆amp; httpcore的依赖项，然后添加排除节点以排除它们。

wilio-java-sdk-6.3.0-jar-with-dependencies.jar 包含 httpclient（4.2.6）和httpcore（4.2.5）

<dependency>
    <groupId>org.apache.httpcomponents</groupId>
    <artifactId>httpclient</artifactId>
    <version>4.2.6</version>
</dependency>
<dependency>
    <groupId>org.apache.httpcomponents</groupId>
    <artifactId>httpcore</artifactId>
    <version>4.2.5</version>
</dependency>

twilio-7.9.1-jar-with-dependencies.jar 包含 httpclient（4.5.2）和httpcore（4.4.4）

<dependency>
    <groupId>org.apache.httpcomponents</groupId>
    <artifactId>httpclient</artifactId>
    <version>4.5.2</version>
</dependency>
<dependency>
    <groupId>org.apache.httpcomponents</groupId>
    <artifactId>httpcore</artifactId>
    <version>4.4.4</version>
</dependency>
