Subject Error message while using ant-contrib.jar - "taskdef A class needed by class net.sf.antcontrib.platform.ShellScriptTask cannot be found: ExecTask"
Date Mon, 22 Mar 2010 10:04:52 GMT
Hi All,

I am wanting to use for-loop task that is available through ant-contrib.jar but I am getting
the error message that is pasted below. By reading the old threads on similar problem (http://www.mail-archive.com/user@ant.apache.org/msg23803.html),
I feel that this could be a classpath issue. Any suggestions to fix this problem?

Due thanks for any help!
Ritu
P.S. : I am using Eclipse IDE versions 3.3, Ant version 1.8.0, and ant-contrib-1.0b2. 

Error Message =

Big Picture =

What I am trying to do with the ant script is as follows:

I am searching for certain lines in a file, and if the lines are found they should be written
to an output file. Because I need to write each matching line in a separate file, I am using
a for-loop. A sample scenario:

1) Content of File.asl =
    readInt(x)
    readInt(y)
    readDouble(z)
    writeInt(x)
    sumInt(x,y)


2) Run ant script and extract lines with read* and write them to separate files.

   Contents of output1.asl =    
    readInt(x)
   
   
   Contents of output2.asl =
    readInt(y)

   Contents of output3.asl =
    readDouble(z)
