After getting this into your development environment, if the problems stick around, do the following:
common.raildiagramsprojects, right click them, and choose 'Maven' -> 'Update project...'. Click 'Select All' to select all projects. Select only 'Refresh workspace resources from local filesystem' and 'Clean projects' at the bottom. 'Update dependencies' should always be selected. Click 'OK'.
- If needed, rebuild all projects.
