I did not answer your question fully.
Generally, this has something to do with the order in which entries are
listed in your classpath.
Make sure the version of the dependency the code is using is that one that
is in your class path first.
Take a look at the following documentation for additional information on
how classes are discovered in the classpath:
So lets say we have two jar files that containing the class
(1) a.jar contains the class org.apache.flume.formatter.output.BucketPath
with the method sanitizeString()
(2) b.jar contains the class org.apache.flume.formatter.output.BucketPath
with the method escapeString()
If your classpath is as follows:
And your code is trying to invoke
org.apache.flume.formatter.output.BucketPath.escapeString() you will have
This is because BucketPath was found first in a.jar but that definition
does not contain the method escapeString()
You will need to reorder the jar file entries in the class path so that the
correct version is picked up and used in your application.
