We are working with Maven core team to improve performance of the
dependency resolution as well as few other things that would make Maven
work better inside Eclipse.
Though I have few comments on initial performance comparison between
Maven CLI and m2eclipse.
First of all it been unclear what time is actually been compared and
to make fair comparison it should been a clean project in both cases
(perhaps even with automatic builds turned off in the IDE).
Another point to note is that when building in Eclipse, "Project /
Clean" action is flushing dependency information, so it will not only
recompile given project, but will update projects that may depend on the
cleaned one. That obviously won't be the case in CLI and it is really
hard to do the fair comparison in such conditions. To address the
resolution issues, we will split dependency resolution out of the JDT
build, so in our prototype it has smaller impact on the build time and
also made workspace resolution more robust.
Hope that helps.

Same thing here. It was better with m2eclipse 0.10, but this has some
other major issues.
Things to improve on 0.12 imo (applicable for a multimodule maven setup):
* snapshots are always checked for updates, even when
<snapshotPolicy>never</snapshotPolicy> is added to all repositories
* when cleaning all projects, for each projects, all dependenat
project poms are read / parsed analyzed. In Progress view it says:
updating (projectname): reading (projectname)/pom.xml. This takes
about 0.75s per pom.xml. I think it should cache this, so that on a
refresh/ clean this delay happens only once per dependency-project

Hi,
I also suspect that the m2 version embedded in the plugin has a
different strategy for resolving artifacts. I struggled to create
a test
project but I was not able to find the cause. Here, we overwrite the
central repository to point to a local proxy, but in Eclipse, maven
tries to resolve artifacts from completely different repos (like
apache-snapshots etc.). I don't know why, and the 2.0.8 never does
that.

Stefan
