Whenever I type mvn -version to check version installed it says that "mvn is not an internal or external command" in cmd.
I have added images to show that I have added environmental variable and the path. do check those and help out.
UPDATE :
After having been told that i have to remove \bin from environment variable of both JAVA_HOME and MAVEN_HOME. now I'm getting error in cmd as JAVA_HOME is not defined.

Your
MVN_HOMEshould be the maven root folder (G:\compressed\apache-maven-3.8.4) not up to thebinfolder.Change
MVN_HOMEvariable toG:\compressed\apache-maven-3.8.4then open a new cmd prompt then the command will work.
