Subject RE: while-like structure in Ant
Date Sat, 28 Jul 2007 22:26:41 GMT
Sorry everybody for the late replay. I am trying to implement that while structure as I explained
before. I am using javascript for that. However, I can not create a http task in javascript
code. That part of the code is:

myhttp = project.createTask("http");
myhttp.setUrl("a url address");

The error is: javax.script.ScriptException:
TypeError: Cannot call method "setUrl" of null <<Unknown source>#5> in <Unknown
source> at line number 5

Any help is appreciated. Thanks in advance.

The ant-contrib project is providing conditional tasks which may help,
if you want to have your own syntax and the very specific url
as a condition (like you wrote), maybe using a script (using scriptdef
example) would be a good fit.


i would go via  and a scripting language running in
(JRuby, Groovy, Beanshell ... )

or use the AntBuilder@Groovy
