[Htmlunit-user] Getting NoSuchMethodError exception in HTMLUnit 2.33

[Vasudevan C. <vco...@gm...>]

Hi,

   I was migrating my web application from HTMLUnit 2.23 to 2.33.
   The project was built and while executing getContentAsString method on
   WebResponse, I am getting the Error mentioned in the subject line.

    Below is the error copied from the console

   Caused by NoSuchMethodError:
org.apache.commons.io.IOUtils.toString(Ljava/io/InputStream;Ljava/nio/charset/Cha
rset;)Ljava/lang/String;
->>  244 | getContentAsString in com.gargoylesoftware.htmlunit.WebResponse

 Am I doing something wrong?. All the dependent libraries are there in the
project.

  I appreciate your help in advance.

Regards
 Vasu
