[ERROR] No compiler is provided in this environment. Perhaps you are running on a JRE rather than a JDK?

Solution:

On your Eclipse IDE, go into Window > Preferences > Java > Installed JREs > and check your installed JREs. You should have an entry with a JDK there.

Control Panel > Java > Java Control Panel > Java > View > change to jdk.

Then Right-Click on your Project -> Maven -> Update Project
