I'm using the m2eclipse plugin for eclipse to build my project, but I miss having the errors and warning of my build show up in the Problems tab. I use a maven project builder to build my project and don't use the default java builder in eclipse. I would really love a way to get all the errors and warnings that I can see when editing a file to show up in the problems tab, and I would like this tab to show problems for my whole project.
Is there a way to do this?
You are doing something wrong. Per default, m2eclipse activates the java builder and shows errors / warnings.
Did you by any chance check out a multi-module maven project and convert it to a single eclipse project? If yes, you need to Import -> Existing Maven Projects and select the projects underneath the root.
Otherwise, you may just have to right-click the project and select Maven -> update Project Configuration.
If neither of these help, please provide more info.
