Idea uses the MVN command to package and report an error, which is not available

The error reporting problem is shown in the figure ：

mvn :  Cannot be “mvn” Item identified as  cmdlet、 function 、 The name of the script file or runnable program . Please check the spelling of the name , If the path is included , Please make sure the path is correct , then try again .
 The position of   That's ok :1  character : 1
+ mvn -v
+ ~~~
    + CategoryInfo          : ObjectNotFound: (mvn:String) [], CommandNotFoundException
    + FullyQualifiedErrorId : CommandNotFoundException

Found several ways online , To configure maven environment variable 、java environment variable 、 System environment variable 、 User environment variable To no avail ;

Solution ：

Later, I found that there was no need to add mvn that will do

clean package -DskipTests

ha-ha ！ Ruthless .
