Re: [m2e-users] New checkout of working project has m2e persistently com

I was getting a similar error a little while ago... (I don't know if it was connection time outs but the maven pom editor was reporting the "Could not find ... from http://repo.maven.apache.org/maven2 was cached in the local repository, resolution will not be reattempted until the update interval of central has elapsed or updates are forced.")

We do experience occasional network hiccups here so that could have been it.  I also went into the preferences and did a rebuild of the local index.  Either the network issues got resolved or the rebuild played a part.  Can't be sure but maybe a rebuild will help for you too?

If you want to try, its Preferences->Maven->User Settings and click on Reindex next to the Local Repository input.

I would suggest checking your Anti-Virus, in p2 people have run into issues where the AV (most if not all reports have been AVG I believe) is causing timeouts.

"connection timed out" usually means networking related problems. Are
you sure windows firewall is not playing tricks on you?

I've been working on a Maven project with my Eclipse running on a Linux box.  Today I tried getting my Win7 environment up to date.  I have the latest 3.x version of Eclipse on both boxes.  When I checked out my working project from SVN on the Win7 box, I had a bunch of errors like this:

Missing artifact aopalliance:aopalliance:jar:1.0
-----------------

The first two are somewhat unique, but there were many occurrences of the third one, with different coordinates.

The project builds fine from the command line outside of Eclipse.

I've tried doing "Update Project", both with and without the "Force update of snapshots/releases" flag.

I also tried "Project"->"Clean..." and selected "Clean all projects".

I tried entering those two urls that it's claiming it's failing to connect to, in both my external Firefox, and in the internal Eclipse browser.  No problems there.

When I explore the "Maven Dependencies" tree in the Package Explorer, I find all of these libraries that m2e says it can't find (the "Missing artifact" message).

I've also tried restarting Eclipse.  No change.
