How do you manage developing with multiple versions of Grails using Windows?

Question

We\'ve been using Grails for a little while now and have been through a few Grails versions now. We don\'t always want to migrate our \'older\' apps immediately but often us

I have the same issue as you. For my concern, I have written a batch script (grails_version.bat) accessible from my Windows PATH home.

Set up your GRAILS_HOME to your standard Grails version and each time you want to run a Grails app into another version than the standard one, open a command prompt, run the batch script (>grails_version) and run your grails commands (ex: grails run-app).

If your are using IntelliJ, you can configure the grails version per application.

Here is the code:

@echo off

set v11=1.1
set v111=1.1.1
set v12M2=1.2-M2
set v12M3=1.2-M3
set v12M4=1.2-M4
set /p grails_version= What is the grails version (%v11%, %v111%, %v12M2%, %v12M3% (default), %v12M4%)?
if "%grails_version%" == "%v11%" goto :set_grails_home 
if "%grails_version%" == "%v111%" goto :set_grails_home 
if "%grails_version%" == "%v12M2%" goto :set_grails_home 
if "%grails_version%" == "%v12M3%" goto :set_grails_home 
if "%grails_version%" == "%v12M4%" goto :set_grails_home 
if "%grails_version%" == "" goto :set_grails_home_default 

:no_valid_input
echo The input version is not valid
exit

:set_grails_home_default
set grails_version=%v12M3%

:set_grails_home
set GRAILS_HOME=D:\Install\grails\grails-%grails_version%
path = %GRAILS_HOME%\bin;%PATH%
echo GRAILS_HOME=%GRAILS_HOME%

Enjoy.
