- From the menu, select "Window-->Show View-->Other..."
- In the dialog, select "Maven-->Maven Repositories" and hit OK.
- In the Maven Repositories view, right-click "Local Repositories-->Local Repository" and select "Rebuild Index" from the popup menu. If asked if you're sure you want to rebuild the index, hit OK.
If that doesn't work (it should), try right-clicking the project in the Explorer view, selecting "Maven-->Update Project..." from the popup menu, ensuring that "Update dependencies" is checked in the dialog that appears, and hitting OK.
BTW, you probably want to add <scope>runtime</scope>
to your dependency
element in the pom file, although that's not related to your issue.
