Question

我一直在：

Exception in thread "main" java.lang.NoSuchMethodError: org.apache.http.conn.ssl.SSLConnectionSocketFactory.<init>(Ljavax/net/ssl/SSLContext;Ljavax/net/ssl/HostnameVerifier;)V

Visual description说明了所有添加的罐子（左侧）及其版本供检查。

尽管添加了所有需要的罐子，尝试了所有不同的罐子和版本，甚至尝试更改项目的设置以使用1.6 1.7而不是1.8 ...

有什么想法吗？

假设您的项目是使用Maven构建的，将其添加到pom.xml应该会解决这个问题：

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

NoSuchMethodError：org.apache.http.conn.ssl.SSLConnectionSocketFactory
