Try the following steps:

1. Make sure you have connectivity (you can browse) (This kind of error is usually due to connectivity with Internet)

2. Download Maven and unzip it

3. Create a JAVA_HOME System Variable

4. Create an M2_HOME System Variable

5. Add %JAVA_HOME%\bin;%M2_HOME%\bin; to your PATH variable

6. Open a command window cmd. Check: mvn -v

7. If you have a proxy, you will need to configure it

8. Make sure you have .m2/repository (erase all the folders and files below)

9. If you are going to use Eclipse, You will need to create the settings.xml

Delete all files under the .m2 repository folder and rebuild the project.
