Hi @saurabh.gupta1233 ,
This problem is most likely caused by a maven version older than 3.6.3 which became required starting from AMPS 8.3.0.
You should be able to resolve this by setting the ATLAS_MVN environment variable to the never maven version as explained here: Changing the default Maven version
Can you try and let us know?
There are some more details about the version compatibility in the AMPS release notes: Announcing AMPS 8.3.1
Cheers,
Caterina
