## Validación personalizada { #custom-validation }

Podría haber casos donde necesites hacer alguna **validación personalizada** que no puede hacerse con los parámetros mostrados arriba.

En esos casos, puedes usar una **función validadora personalizada** que se aplique después de la validación normal (por ejemplo, después de validar que el valor es un `str`).

if ($distributionSha256Sum) {
  if ($USE_MVND) {
    Write-Error "Checksum validation is not supported for maven-mvnd. `nPlease disable validation by removing 'distributionSha256Sum' from your maven-wrapper.properties."
  }
