Spring Tool Suite (STS) Maven ‘Add Dependency’ does not work

There is small but annoying issue in Spring Tool Suite. After right-click on a project and selection of "add dependency" no search results are found.

1. Preferences -> Maven -> Download repository index on startup
2. Restart STS
3. Wait for index download

Or add to pom.xml
