 (execution: default-compile, phase: compile)
  1. Go to Run -> Run Configuration,
  2. Double click on Maven Build,
  3. Under new configuration type clean build under Goal,
  4. Run the new configuration.
  5. All missing repo's will get downloaded from the central (nexus) repository and the error should go away!

You can also try Right-click your pom.xml -> Run as -> MAVEN BUILD

If that does not work then - Right click on pom.xml -> Maven -> Update Project... -> Check Force update of Snapshot\Releases.
