Independent of maven: you are using an old version of Mahout. You may find
that some of the programs work better in the trunk than in the 0.5 release.
Also, the wiki documentation generally moves forward with the current trunk
and so it may be confusing.
LDATopic is only giving topic 0. What about other topics? and how to get
those? I have used the following command
mahout ldatopics -i mahout-work/abc/abc-lda/state-20 -d

There are several good ways to deal with this. The idea of super-products
which are composite features that are derived from history is a good one.
I would recommend that you limit the number of such super features by
first finding which products cooccur within a reasonable time window more

mvn install is the better command for this stuff.
"mvn install -DskipTests"

There's no magic here, it's just suggesting you create a bunch of
those ItemItemSimilarity objects, one for each item-item similarity
that you know about.
Collection correlations =
new ArrayList();
correlations.add(new GenericItemSimilarity.ItemItemSimilarity(1, 2, 0.5));

Agree, this is all specific to Eclipse. The Maven build works from the
command line. I don't use Eclipse and don't like it much, myself;
IntelliJ seems to have no trouble with Maven integration. I always use
the command line tools though.

I think you need mvn package to create artifacts but that is just a first
simple guess.

I can run the examples under the mahout-distribution directory fine.
However cannot run the bin/mahout command, gives following errors.
mvn exec runs ok fine with mainClass (standard syntax) given (ran few

How
I am talking about the implementations available in Mahout where you can
find similarity between users by analyzing some datamodel and then
recommend items based on that.
If this can solve your problem. I see this implemented in Mahout. And
its very easy to use.

Are you talking about CF? Can you please explain a bit?
To be clear, for my use case, temporal sequence is important.
