Hello m2eclipse experts, checking out a Maven project from SVN with "Checkout as Maven project.." throws an exception (error window with a very general message). The project was checked out nevertheless (as a M2 project) and I can work on it (POM editor is up and running, M-icon is visible), but there are no Maven Dependencies resolved. The project's POM is disregarded .. in the POM I added a dependency component from a proxy repository (Archiva), but it is not found/retrieved. Even more strange: there is no "Maven Dependencies" entry under the project root. This dependency folder is totally missing. Any idea ?
I use RAD 7 (Eclipse 3.2) and the latest and greatest M2Eclipse via update manager. I copied the POM and the log entry below. Thanks !!!!!
