bernd hopp commented on MAHOUT-615:
-----------------------------------
yes, you where right, thanks. Besides Guava, I needed log4J and uncommons.math
to get mahout up and running. This is obviously not an issue in mahout itself,
but a hint at the download-page may prevent others from running into the same
problem.
> unable to instanciate FastByIDMap<PreferenceArray>, ClassNotFoundException
> for com.google.common.base.Preconditions

>
> 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.
