Why is this an issue?
The imports part of a file should be handled by the Integrated Development Environment (IDE), not manually by the developer.
Unused and useless imports should not occur if that is the case.
Leaving them in reduces the code’s readability, since their presence can be confusing.
Noncompliant code example
package my.company
import kotlin.String // Noncompliant; "kotlin" classes are always implicitly imported
import my.company.SomeClass // Noncompliant; same-package files are always implicitly imported
import java.io.File // Noncompliant; "File" is not used
import my.company2.SomeType
class ExampleClass {
val someString = ""
val something = SomeType()
}
Compliant solution
package my.company
import java.io.File
import my.company2.SomeType
class ExampleClass {
val someString = ""
val something = SomeType()
lateinit var fileUsage: File
}
Exceptions
Imports for types mentioned in KDoc comments are ignored.
