java - How to preinstall Eclipse m2e configurators (Plugin execution not covered by lifecycle configuration)

Question

When importing maven projects into Eclipse IDE fresh install, there is a pop-up question to "Setup Maven plugin connections"

If not to install there will be errors shown in pom.xml like

Plugin execution not covered by lifecycle configuration: org.eclipse.tycho:tycho-packaging-plugin:0.20.0:validate-id (execution: default-validate-id, phase: validate)

How to install m2e configurators at any time (e.g. before when preparing Eclipse package for team, or again after interactive installation failed over network)?

Answer 1

You can install M2Eclipse connectors at any time by going to "Window > Preferences > Maven > Discovery".

Then when you click "Open Catalog", you will be greeted with a pop-up that will display all available M2E connectors to install. You need to select the one you want, click "Finish" and follow the standard installation process.
