maven 3.0.3 - performance with version ranges
maven 3.0.3 has terrible performance and memory usage when using version
ranges. This has a knock on effect using m2e
It takes maven ages to update the maven dependencies.
I have a main project with a some version ranged dependencies which in
turn have versioned ranged dependencies. Outside of eclipse it takes
many minutes and considerable memory to get a successful build. Most
time is spent resolving the dependencies.
I have also run maven offline when I know I have all dependencies in my
local repo and it is still very, very slow.
In m2e (and workspace resolution on), you can check out a dependency
that is very simple and this triggers a re-build of the main project.
The same happens when you delete the dependent project or make pom
version changes to it. So in eclipse this becomes really tedious
especially if you have 4 or 5 related projects checked out. You end up
sitting and waiting for your workspace to be re-built all the time.
I understand what maven is doing but I do believe it could be done a lot
better when resolving version ranges.
I also know maven 3.0.3 uses aether 1.11 to so its dependency management.
I'm really keen to try and find a solution. aether 1.12 has been
released. Is there anyway I can hook this into maven 3.0.3
Does aether 1.12 solve
Is there a pre-release of maven 3.0.4 out there yet that I can try and
does it use aether 1.12 ?
Thanks
Paul

+1 for using aether >1.12, this reduced 2:00 compile time to ~45 seconds.

FYI, You can tell maven 3.0.3 to work with aether 1.13 (I think this is the latest release) just by dropping aether jars in $MAVEN_HOME/lib/ext. They should take precedence over the aether 1.11 bundled with maven in $MAVEN_HOME/lib.
I did that with aether 1.12 and there was no issue, at least for my projects.

wow!
Dropped in aether 1.13 into apache maven lib/ext (so patched applied
external to eclipse) and also updated the m2e embedded runtime plugin
org.eclipse.m2e.maven.runtime_1.0.1.201106291304 (as a quick test) and
now as an example a build that took 1 minute 43 secs now only takes 5
seconds.
Will build our own embedded runtime as instructed below now.
Thanks for everyone's help.
Any ideas when an official maven 3.0.4 release will happen as well as an
official maven 3.0.4 embedded runtime m2e connector ?
