Exception in thread "main" java.lang.NoSuchMethodError: org.apache.commons.io.FileUtils.moveFile(Ljava/io/File;Ljava/io/File
a program of mine is making a call to this method . It was working fine till before few days. and now it is throwing this exception.
Since the exception is from an apache FileUtils class,it cant be any problem with my program also. So what could be the possible cause for this?
