Rookie error (vii)--console after executing the mvn command prompt ' cmd ' is not an internal or external command

The recent use of the MVN command under CMD will always appear after execution "' cmd ' is not an internal or external command, or an executable program or batch file," such as:

Although the execution of the command was successful, it would not have any effect, but as a late obsessive-compulsive disorder, I could never tolerate it. First, the ability to execute the MVN command correctly, stating that MAVEN's configuration is no problem, and where is the problem? Look for it. The last location is the environment variable problem, look at the system variable path, found that there is a lack of %systemroot%\system32;%systemroot%, so decisive Plus, again execute the MVN command, Found that the sentence has disappeared!

Note: After modifying the path path, you can reopen the command-line window.

Obsessive-compulsive disorder is my motivation to pursue perfection!
