IDE improves developer productivity by performing the following functions:
Creating boilerplate code
Carrying out code completion
Identifying syntax issues
Performing tasks such as compilation, unit testing, and deploying to web/app servers
While Maven is primarily intended to be a command-line tool, IDEs help developers enjoy as well as exploit Maven features in better ways. The integration of Maven with IDE helps us to automatically download dependencies and quickly search for dependencies through the UI, among other benefits.
The IDE integration of Maven has improved over the years and most Maven features can be set through IDE now.
