java – How do I enable index downloads in Eclipse for Maven dependency search?
- In Eclipse, click on Windows > Preferences, and then choose Maven in the left side.
- Check the box Download repository index updates on startup.
- Optionally, check the boxes Download Artifact Sources and Download Artifact JavaDoc.
- Click OK. The warning wont appear anymore.
- Restart Eclipse.
Tick Full Index Enabled and then Rebuild Index of the central repository in Global Repositories under
Window > Show View > Other > Maven > Maven Repositories, and it should work.
The rebuilding may take a long time depending on the speed of your internet connection, but eventually it works.
