The best solution is to avoid snapshots altogether. They are fine for dependencies among different modules of the same project, but cause problems when used for inter-project dependencies. When using snapshots you never really know what build includes what exact dependencies versions, so you can't reliably tell if certain change was tested or not, for example. Another problem is that you have to modify your pom.xml during or right before the release, which is the worst possible time to do that. If you really have to develop several projects in lock- step, then they probably is one project and should be merged together.
If you absolutely must use snapshots, then you have couple of options. Either import all involved projects in m2e workspace, in which case m2e will use workspace sources and compiled classes. Or remove snapshots from local repository and force dependency resolution of workspace projects, in which case m2e will resolve artifacts and their corresponding sources at about the same time. -- Regards, Igor On Sun, Jul 12, 2015, at 08:57 AM, Dagan Sandler wrote: > Thanks for the quick reply. > > Do you know what's the quickest/easiest workaround to fix this when > encountered?
