Subject Re: [PATCH] Allow check for values on if/unless <target>
Date Tue, 10 Oct 2000 06:49:50 GMT
<target name="myName" if="myprop="> and/or <target name="myName" if="myprop=${aproperty}">
(iff aproperty is 'empty' (the empty string)) will throw an Exception, won't it? (I don't
applied this patch, just had a quick look at it and 

+        String value = 
+          ProjectHelper.replaceProperties(condition.substring(pos+1),
+                                          project.getProperties());

seems not to work in the above conditions since pos+1 should be invalid? 

Maybe I'm completely wrong with this, it's quite early in Germany (at least for for some people
like me :-) )

  Subject: [PATCH] Allow check for values on if/unless <target>

  This small patch makes possible to check for specific values of properties on if/unless
attributes of <target>s. Hope you guys agree on incorporate it to 1.2.
  <target name="a" if="myprop=${yourprop}" >
  This helps a lot on builds that use properties to specify configuration options with different
alternative tasks for different options.
