Getting java.lang.NoClassDefFoundError: com/google/common/io/ByteSink

[Oliver]

Our application downloads reports daily and has been running well for over a year.

Last night we saw this error for the first time:

java.lang.NoClassDefFoundError: com/google/common/io/ByteSink            

Has anything changed in the API that could have caused this?

Hi Oliver,

Which Java library are you using? old or new one?

We're using the new one (version 1.18.1)

Hi Oliver, 

We haven't changed anything about the new Java library. 

Loos like the ByteSink class in the guava library is missing. 

Let me confirm following to narrow down the issue: 

 - Are you using Maven or using dependent jars directly?

 - Either way, please confirm guava-jdk{jdk-version}-{guava-version}.jar (e.g. guava-jdk5-14.0.1.jar) is in place and your classpath is correctly set that covers the directly

   where that jar is placed. 

Best,

- We use Maven

- guava-jdk5-13.0.1.   However, we changed to guava-jdk5-14.0.1 and this seems to have fixed the problem.

Thanks

Oliver
