I do have this type of problem too. But everything work out fine if you
ignore it. Any reason behind this?

This is on my MacBook Pro, and I have the current JDK that Apple
provides (1.6.0_29). I just installed the current Maven, which
describes itself as Apache Maven 3.0.3 (r1075438; 2011-02-28
12:31:09-0500). This is my first ever install of Maven. I am also
just getting started with Mahout. I checked out the trunk using svn,
and then built with `mvn install`, as described in
https://cwiki.apache.org/confluence/display/MAHOUT/BuildingMahout; the
tests took about an hour (not the 15 minutes suggested in the
instructions on shortening the build). That has been the full extent
of my experience with, and knowledge of, Maven and Mahout.
I am running Eclipse Helios Service Release 2, Build id 20110218-0911.
I just installed the latest m2e: my Eclipse plug-ins listing includes
version 1.0.100.20110804-1717 of m2e / UDC integration Marketplace,
m2e logback appender, m2e logback configuration, and m2e Marketplace,
as well as version 0.14.0.201109270543 of m2e connector for the
mavenarchiver and pom properties. This is my first ever install of m2e.
Following the Mahout quickstart, I then used "Import Existing Maven
Projects" in Eclipse to import all the Mahout that I just built.
During that process I was faced with the following window:
If your mail program has chopped out my picture, here is a
description. It is a window whose title is "Import Maven Projects".
The first thing in the window is a text area with a heading saying
"Setup Maven plugin connectors". I have no idea what Maven plugin
connectors are --- nor what I can/should do about setting them up. I
thought I had already installed m2e, but apparently it does not really
get settled in until you try to use it. This window contains a table
whose first column is "Maven build", second column is "Action". The
rows are organized into two groups. The second, and thankfully
larger, group is headed by a line with a green checked circle
indicating, I suppose, that there is no problem. It is the first
group, headed by a line with a red X circle, that prompts this
epistle. It has just one line, for core/pom.xml. Lower in the window
is a "Description" section, which says "No marketplace entries found
to handle maven-antrun-plugin:1.6:run in Eclipse. Please see Help for
more information." Naturally, there is no "Help" evident.
I clicked on the "Finish" button in the lower right hand corner, and
the import eventually finished. I was told I have to restart Eclipse,
which I did. As it was later restarting, it got wedged and I had to
forcefully quit it. I restarted Eclipse again, and have been going
through its "Problems" list. I cleared up a few that required only
"Maven |> Update Project Configuration...". But I do still have the
problem with core/pom.xml. Following is a picture of its details.
The Description says "Plugin execution not covered by lifecycle
configuration: org.apache.maven.plugins:maven-antrun-plugin:1.6:run
(execution: default, phase: compile)". It is On element pom.xml In
folder mahout-core, Location line 53.
QuickFix on this Problem is not promising. It offers two choices,
neither of which looks good; here is a picture:
For extra grins, I also have two more Problems. Here is a picture of
the Properties of one:
The description says "maven-dependency-plugin (goals
"copy-dependencies", "unpack") is not supported by m2e." and it is at
line 54 in pom.xml of mahout-examples; the same problem is also in
mahout-integration. There is no QuickFix offered for these two.
Why do I have these three problems, and how do I fix them?
Thanks,
Mike
