Via the Maven index, you can search for dependencies, select them and add them to your pom file. To download the index, select Windows > Preferences > Maven and enable the Download repository index updates on startup option. After changing this setting, restart Eclipse. This triggers the download of the Maven index.
Maven uses HTTP to download its dependencies along with the dependencies of the Maven project (such as Camel). If you run Maven and it fails to download your required dependencies it's likely to be caused by your local firewall & HTTP proxy configurations.
You can find this in Window > Preferences > Maven > User Settings , and then point Global Settings to your external maven settings. xml . Then i removed the broken projects and re-added them, and the Maven Dependencies library appeared again.
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.
