Hey @Vinod, your command to check for maven version is wrong. Use the following command:

mvn --version

that did not work ..

maven install files in maven folder as give here :

[ec2-user@ip-172-31-6-83 bin]$ pwd
/opt/apache-maven-3.6.0/bin
[ec2-user@ip-172-31-6-83 bin]$ ls -ltrh
total 32K
-rwxr-xr-x. 1 501 games 1.5K Oct 24 18:38 mvnyjp
-rw-r--r--. 1 501 games 1.7K Oct 24 18:38 mvnDebug.cmd
-rwxr-xr-x. 1 501 games 1.5K Oct 24 18:38 mvnDebug
-rw-r--r--. 1 501 games 6.2K Oct 24 18:38 mvn.cmd
-rwxr-xr-x. 1 501 games 5.7K Oct 24 18:38 mvn

What exactly are you trying to do?

---

I just need maven work as it was tought, i just want maven reposnd as expected after installing, which is not is the case.

---

seems I am close to the resolution .. it looks to be environmental variable need be set.  I tried below , it works..

maven --version respond seems fine. Make sure you've added Maven to the path which I think you already have. Did you expect anything else?
