I installed latest version of Netbeans (8.0.2) with Maven (4.27.1) installed as a plugin (so by default).

When I try to build latest version of optaplanner (6.3.0) I get exception 

Building OptaPlanner examples 6.3.0.Final

To see the full stack trace of the errors, re-run Maven with the -e switch.
Re-run Maven using the -X switch to enable full debug logging.

What can I do in order to build this project ?

4.27.1 can be a Netbeans Maven Plugin version, but not Maven version (there is no Maven 4 yet). You need to find out in settings what Maven is used and maybe install a new version in your system if you have Maven 2 (instead of 3) installed.

in the setting of intellij there is a option called maven, in which you can set the maven version intellij should use.

As I recall the default ist 3.10 or so but if you have maven installed (with an other version) you can select it in the intellij settings
