To index downloads are disabled search results may be incomplete

1. In Eclipse, choose on Windows > Preferences, and then pick Maven in the left side.

2. Check the receptacle "Download repository index updates on startup".

Optionally, mark the receptacles Download Artifact Sourcesand Download Artifact JavaDoc.

3. Click OK. The sign won't resemble anymore.

4. Restart Eclipse.

To enable index downloads in Eclipse for Maven dependency search, follow these steps:

Open Eclipse Preferences:

Go to Window (or Eclipse on macOS) > Preferences.

Navigate to Maven Settings:

In the Preferences dialog, expand Maven and then select Download.

Enable Index Downloads:

Check the box that says Download repository index updates on startup. This option ensures that Maven repositories' indexes are updated and available for search when Eclipse starts.

Apply and Close:

Click Apply and Close to save the changes.

Update Project:

Right-click your Maven project in the Project Explorer, select Maven, and then click Update Project to refresh the project's Maven dependencies.

This should enable Maven to download and use index files, improving the efficiency of dependency searches within Eclipse.
