Enter mvn -v on the command line, the corresponding version and prompt message will appear, and the maven environment will be configured;
Enter mvn -v on the command line and see if it was unsuccessful; see, the maven downloaded earlier is a source code, and there is no bin directory, so it cannot be run;
Make another copy, and modify the relevant environment variables, that's it; as shown below;
