After download the project using,
bzr branch lp:~dhis2-devs-core/dhis2/2.18
I am getting the following error when trying to import DHIS2 project using Bazaar into Eclipse EE Luna Version 4.4.2:
[Error 206] The filename or extension is too long: u 'D:/workspace/.metadata/.plugins/org.vcs.bazaar.eclipse.core/bzreclipse5417078662519156113.tmp/.bzr/checkout/limbo/new-2/dhis-web/dhis-web-commons-resources/src/main/webapp/dhis-web-commons/javascripts/ext/resources/themes/images/gray/form-invalid-tip'
Try installing the m2e plugin which provides maven integration for eclipse:
http://www.eclipse.org/m2e/
After installing, you can go to File > Import > Existing Maven project. Click Next, locate the root folder of your checkout and click Import.
