It is possible that you are hitting into incompatibility of the
embedded Maven runtime. As a workaround you can configure m2eclipse to
use external Maven installation to launch Maven in the ide and select
the same Maven instance as you are using in the command line, e.g.
latest Maven release is 2.0.9 can be downloaded from
http://maven.apache.org/
However if your build also fail in the command line you should address
your question to the maven users maling list. See
http://maven.apache.org/mail-lists.html

Hello,
I am a bit new at all of this and I am having trouble understanding what is
going on.
Basically I have imported a maven project into Eclipse using (File>Import)
and now Eclipse recognizes it as a Maven project. I can execute many goals
on that project like compile and package and they work successfully.
However, when I execute the "Deploy" goal, I get an error during Maven
execution.
Below is the list of events while deploying. I have removed the first part
which are the transfers because they take a lot of space. It is a bunch of
transfers which were completed followed by some checking statements followed
by a warning and 2 errors. Let me know if you need more information to help
me with this issue.
P.S: Eclipse Version: 3.4.0
Thank you.
