Well, this means you need Google Guava in your project one way or the other. I don't know if GWT has it, but may do, in which case there should be no issue. If not, you need to get the library into your project. This is not really to do with Mahout.

> Key: MAHOUT-615
> URL: https://issues.apache.org/jira/browse/MAHOUT-615
> Project: Mahout
> Issue Type: Bug
> Components: collections
> Affects Versions: 0.4
> Environment: Windows 7, Java 1.6.0.24, reproducable in eclipse helios and netbeans 6.9
> Reporter: bernd hopp
> Assignee: Sean Owen
>
> this code:
> FastByIDMap<PreferenceArray> map = new FastByIDMap<PreferenceArray>();
> throws an java.lang.ClassNotFoundException, class com.google.common.base.Preconditions cannot be found.
> The error is thrown in FastByIdMap, ln 76, where "Preconditions" cannot be found. In this project, im using the google web toolkit, which is shipped with the Preconditions-class, what propably confuses the class-loader. Anyhow, when im trying the line shown above in netbeans, without any references to gwt, it fails with the very same exception.
> Any questions, suggestions, workarounds etc. appreciated, thanks.
