javax.persistence missing?
Hi,
I've been using the compiled version of mahout 0.3. I now want to work from the source package so that I can incorporate some changes and so forth.
Previously I just associated the JAR files from the compiled version of mahout with my IDE (Netbeans). It appears this is not so straight forward with the source package. I've never used MVN beyond the install commands so don't really get it (Package manager of types).
So I followed the instructions on https://cwiki.apache.org/confluence/display/MAHOUT/BuildingMahout
After completing the steps on the page I do the following -
I go into the core, math, util ,collections directories. I associate the high level JAR's and dependencies with the project. However when I try a rebuild of the project I get told javax.depenciy is missing. Are there libraries that are in the mahout 0.3 compile which are not in the source package?

Ah this appears to be a ctrl-space mismatch! Everything is fine, nothing to see here.

I'm not sure where that javax.persistence dependency is coming from, I
don't see it locally. Perhaps it is related to Steven's build
environment? Steven, could you provide any additional details about
the error, for example which class or package (core, examples, etc..)
is the source of the problem?
As Sean points out the most important thing about Maven's dependency
management mechanism is that it not only resolves direct dependencies
on various packages but also transitive dependences, or packages
depended upon by the packages that mahout depends upon. So for
example, if javax.persistence was needed it would be pulled in
automatically. I don't use Netbeans personally, but I've heard the
maven integration it provides is very usable. You can read more about
it here: http://wiki.netbeans.org/MavenBestPractices
That said, the binary release should have all of the dependencies you
need packaged along side of it. You can package a binary release from
a checked out copy of the trunk by doing 'mvn clean install -Prelease'
from the command-line,

Maven defines the entire build, including dependencies. It's the build
system of record, and should manage all this.
You can use an IDE but it really has to have Maven integration to make
this work seamlessly. IntelliJ does and Eclipse does, and I assume but
don't know if Netbeans does. (And, I should say I strongly recommend
IntelliJ's free edition of the 3.)
Without it, yeah, setting up the dependencies is manual and bound to
break regularly. You're getting some form of this error and it'll keep
happening if you don't use Maven.
(Although I must say I wonder where we get a dependency on javax.persistence?)
