Answer 2

Maven 3.3+ has no more mvn.bat you should use version 2.5.2+ of the maven-release-plugin : https://issues.apache.org/jira/browse/MRELEASE-902

Answer 3

Install Netbeans 8.1 or later to correct this issue.

As @mkleint noted, this is a problem with Maven 3.3.3+ where maven changed the mvn executable extension.You can download the latest version on the Netbeans website.
