问题
Has anyone had to deal with the issues of switching git branches in a project that has Maven (or any other external) dependencies? For example, suppose that in one branch I have a maven dependency, and in another I don't (or have a different version required). Would I have to re-import maven dependencies each time I switch branches or is there a better approach?

It actually depends on an IDE you're using. I haven't noticed any issue with this when using IntelliJ IDEA. It handles any pom.xml changes on the filesystem level very smoothly.
However, some time ago, when I was using Eclipse, I believe I saw such a problem you're talking about. Then there was a need for reimporting Maven projects to have the IDE aware of Maven model changes. I'm not sure how mature is Eclipse support for Maven nowadays though.
