CODE JAVA:
class CustomString extends Task{
private String type, string, before, after, returnValue;
public void execute() {
if (getType().equals("replace")) {
replace(getString(), getBefore(), getAfter());
}
}
private void replace(String str, String a, String b){
String results = str.replace(a, b);
Project project = getProject();
project.setProperty(getReturnValue(), results);
}
..all getter and setter..

est parfait en tant que recherche générale / remplacement d'une seule ligne: sinon, s'il n'y a pas de correspondance, rien n'est mis dans propB !! Merci!
