Re-install package with go tool

How to re-install a package?

$ ll ~/go/pkg/linux_amd64/github.com/kless/GoStart
total 8
drwxrwxr-x 2 neo neo 4096 2012-02-12 10:48 ./
drwxrwxr-x 13 neo neo 4096 2012-02-10 23:52 ../
$ go install -v ./start/
github.com/kless/GoStart/start
$ ll ~/go/pkg/linux_amd64/github.com/kless/GoStart

$ go install -v ./start/

It can not re-install if there is a package already created, and there
is no flag to force it

This is intentional, because the package source haven't been changed since last
'go install', so no need to re-install. If you really want to force the re-install, please
use 'go install -a'.

I'd tested with flag "a" too but it re-install another packages too:

runtime
errors
sync/atomic
unicode
sync
io
math
unicode/utf8
bytes
syscall
time
os
strings
strconv
exp/signal
sort
path/filepath
path
reflect
io/ioutil
os/exec
fmt
exp/inotify
go/token
log
go/scanner
go/ast
go/parser
go/build

Yes, -a will re-install everything needed.
But, I'm still curious why you want to force re-install when no source changes have been made?
The go tool is designed to free you from handling these things, just like make(1).

If you just want to reinstall one pkg, just remove the pkg.a file from $GOPATH/pkg and 'go install'
again.

I know that it's a case very specific so I'll use "go install -a" .
It's for a test to simulate that a package has changed so it can be re-
compiled automatically by my program.

In your test, you could just "touch" one of the
source files to update the modification time.

$ go install -v
$ touch *.go
$ go install -v
github.com/agl/xmpp
$

It's true. Thanks!

And for Windows:

copy /b file.go +,,

Alternatively, you could run `go clean -i <pkg>` to get rid of any installed objects.
