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

Question

我一直在:

可视化描述,说明所有添加的罐子(在左侧)及其检查版本.

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,甚至尝试改变项目的设置以使用1.6 1.7而不是1.8 ...

有任何想法吗？

假设您的项目是使用Maven构建的,那么将此项添加到您的pom.xml应该处理该问题:

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