Hi maheswara,
I believe that you have overcome this issue until now, but this is usually a common mistake when developing custom snaps.
The main issue in most cases is that the version of the build of the Snappack is not increased.
You can use the following:
>mvn clean install -Dsl_build=new_version
or
Chenge the value in the sl_build tag in the pom file and use >mvn clean install
Then remove the old version of the Snappack from SnapLogic. (Manager->Location where the snapplex is uploaded->)
Upload the new version of the Snappack (.zip file) (Manager->Location where the snapplex want to be uploaded).
Go to Designer and refresh the page. In the Snap "Info" tab you should see the new version (Class FQID field)
Kind Regards,
Bojan
