Duplicate option token

Reproduction

All option names, aliases, handler flags, and handler paths must be unique within a command:

src/build.command.ts

import { CommandMajor, Container, Flag, Handler, Value } from 'func'

@CommandMajor()
class BuildCommand {
  @Flag({ name: 'config' })
  useConfig = false

  @Value({ name: 'config' })
  config = ''

  @Handler()
  run() {}
}

new Container([BuildCommand])

How to fix it

Rename one conflicting token or remove the duplicate declaration:

src/build.command.ts

@CommandMajor()
class BuildCommand {
  @Flag({ name: 'use-config' })
  useConfig = false

  @Value({ name: 'config' })
  config = ''

  @Handler()
  run() {}
}

new Container([BuildCommand])
