I'm trying to split a maven project into submodules. It builds fine on the command-line, but when imported into eclipse I get the following error after a while, and then I'm forced to reimport the project.
The project struture is
- my-app
- my-legacy-app
- my-app-shared
It appears that eclipse is hitting an NPE when determining paths when updating the maven project. Where do I go from here to resolve this?
