  please can tell me any solution,

Answer 1

AWS Lambda lets you select a runtime at the time of creation of that lambda function, or later you can change it again. 
So, Create a separate Lambda with the Jar file that you want to run having different dependency and then you can trigger that lambda function from your current lambda function if that's what you ultimately want.

Answer 2

If you have created AWS Lambda Deployment JAR Using Maven, you can use the Versions Plugin, very useful but not-so-well-known Maven plugin. The Versions plugin, as the name suggests, helps you manage versions in your Maven projects. Versions of your dependencies and of your plugins as well.

You can use versions:display-dependency-updates command which will list the dependencies you are currently using, and which ones are due for an update. Then to update the outdated ones you can use mvn versions: set command to go ahead and update versions in pom.xml files.

Finally, once your happy with your new versions, use mvn versions:commit to set your changes in stone. This removes the backup files that the Versions plugin has been keeping, just in case.

If you want to know more search for Versions Plugin. Hope this helped.
