Is there any way to generate a guid in ANT?

Question

I have an ant script to manage out build process. For WiX I need to produce a new guid when we produce a new version of the installer. Anyone have any idea how to do this in ANT

If you are using (or would like to use) groovy this will work nicely.

    
        
            //generate uuid and place it in ants properties map
            def myguid1 = UUID.randomUUID()
            properties['guid1'] =  myguid1
            println "uuid " + properties['guid1']
        
        
        
    

Output

Buildfile: C:\dev\anttest\build.xml
main:
      [groovy] uuid d9b4a35e-4a75-454c-9f15-16b4b83bc6d0
      [echo] uuid d9b4a35e-4a75-454c-9f15-16b4b83bc6d0
BUILD SUCCESSFUL

Using groovy 2.1.5 and ant 1.8
