Description
Reports .kt files that declare no top-level functions, classes, objects, properties or
type aliases. The file may still contain a package header and imports but contributes no
code to the project.
Rationale
// FLAW — file with only a package header and imports
package com.example
import java.io.File
// OK — file declares at least one top-level element
package com.example
fun greet() = "hello"Empty files are usually left over from refactorings — declarations were moved or deleted without removing the surrounding file. They clutter the source tree, dilute grep results and slow incremental builds.
Remediation
-
Delete the file if it is no longer needed.
-
Move pending declarations into the file or merge it with another file in the same package.
