Description

Reports the same import path imported more than once in a source file, whether inside one grouped import (…​) block or spread across several declarations. A repeated import adds nothing and only clutters the import section.

Rationale

Duplicate imports are dead weight: they lengthen the import block, make it harder to see which packages are actually in use, and add noise to diffs and merges. They usually slip in through a careless merge or a forgotten line. Keeping a single occurrence of each path keeps the import section honest.

import (
    "fmt"
    "os"
    "fmt" // FLAW — fmt already imported
)

import "os" // FLAW — os already imported above

import "strings" // OK — imported only once

Remediation

Delete the redundant import line, keeping a single occurrence of each path.
