Answer 1

First, double-check that you have the correct Maven coordinates in the file (groupId, artifactId and version). Look for typos.

This could be caused by a corrupt local Maven repo. You can resolve it with these steps.

Option 1:

1. On your project, right-click: Maven > Update Project

2. In the dialog, check the box: Force Update of Snapshots/Releases

3. Click Ok

Maven will perform a rebuild.

If that doesn't solve your problem then move to option 2

Option 2:

1. Delete your local Maven repo, the .m2 directory on your computer

On MS Windows

either

C:\Documents and Settings\\.m2

c:\Users\\.m2

On Mac/Linux

~/.m2

---

Note, on your OS, you may need to configure your OS to show hidden files.

2. Once .m2 directory is deleted, restart Eclipse

3. On your project, right-click: Maven > Update Project

This will resolve your issue.
