== Why is this an issue?
|
||
|
|
|
||
|
|
Unnecessary imports refer to importing types that are not used or referenced anywhere in the code.

== How to fix it
|
||
|
|
|
||
|
|
While it's not difficult to remove these unneeded lines manually, modern code editors support the removal of every unnecessary import with a single click from every file of the project.
