Question

I have a project I would like to build using multiple configurations. I have a constant that needs to be different between builds but I do not know how to change it based o

Answer 1

I would advise attempting to emulate Maven resource filtering and profile properties

Source filtering

src/templates/MyFile.java

..
@WebService(targetNamespace = "@WS_NAMESPACE@")
public class CustomerWebService {
..

build.xml

    
       
       
          
       
    



    
        
        
        
        ..
        ..
    

Notes:

• The ANT copy task is capable of performing template substitutions.

Build profiles

Property files

Each configuration has a different property file

src/properties/dev.properties
src/properties/qa.properties
src/properties/prod.properties
..

build.xml

Choosing an alternative build profile

ant -Dprofile=qa ..
