How to pull out a substring in Ant

Question

Is there a way to pull a substring from an Ant property and place that substring into it\'s own property?

Answer 1

i would use script task for that purpose, i prefer ruby, example cut off the first 3 chars =

    
    
    
    $${mystring} == ${mystring}
       
  

output =

main:
     [echo] ${mystring} == barfoobaz

using the ant api with method project.setProperty() on an existing property will overwrite it, that way you can work around standard ant behaviour, means properties once set are immutable
