Do this, just as Honza Zidek did:
- Leave Eclipse
- Go to [your-workspace-folder]
- Remove .metadata/.plugins/org.eclipse.m2e.core/nexus
- Remove .metadata/.plugins/org.maven.ide.eclipse/nexus
- Restart Eclipse
- remove [your-home-folder]/.m2/repository/.cache/m2e.
Click Window -> Show view -> Other -> Maven Repositories
In the appeared tab click Global Repositories. Right click on central -> Rebuild Index.
It took me 30 minutes to rebuild it. All the time Progress bar was 0%. Eclipse downloaded about 10Gb in [your-home-folder]/.m2/repository folder. Then it deleted 8Gb.
To check if download is going, just refresh C drive (or the drive .m2 folder is loceted).
