Subject Re: Implementing a loop in ANT
Date Thu, 08 Jun 2006 00:00:41 GMT
Sorry, my boldfaced was turned into *YYY*

Let me repost:

<project  name = "test">
  <taskdef  resource = "net/sf/antcontrib/antlib.xml"/>

  <for list="1,2,3,4,${N}" param = "val">
      <sequential>
          <echo message = "val = @{val}"/>
      </sequential>
  </for>
</project>

Command line:

ant -DN=9

Buildfile: build.xml
     [echo] val = 1
     [echo] val = 2
     [echo] val = 3
     [echo] val = 4
     [echo] val = 9

BUILD SUCCESSFUL
Total time: 2 seconds
