Passing command Line args for a list

Hello

We are tyring to automate an ant task, but finding it impossible to pass a
command line argument to a property inside a list.

We need to pass Name and Description for each agent specified from the
command line. for ex:
ant -f build.xml addNodes -Dagents="d01, d02, d03" -D{node???}='node1' -
D{node_description???}='node1 description'

each agent d01/d02/d03 will need have name and description.

<target name="addNodes" depends="clean">
<input message="Agents Name Seperated By , :" addproperty="agents" />
<for list="${agents}" delimiter="," param="agent">
<sequential>
<input message="Node Name:" addproperty="node" />
<input message="Node Description:" addproperty="node_description" />
<exec>

</exec>
<var name="node" unset="true"/>
</sequential>
</for>
</target>

Any suggestions is greatly appreciated.

thanks

So I see in your example below some input tasks. I'm guessing you'd
rather not using input?

We have to have these inputs for manual execution

Thanks

I'm confused as you are asking about using command line params (via the
-D) but then reusing those for the input task.

As an example from your post:

ant -f build.xml addNodes -Dagents="d01, d02, d03" -D{node???}='node1'
-D{node_description???}='node1 description'

Note you list -Dagents

In your target I see this:

<input message="Agents Name Seperated By , :" addproperty="agents" />

So the property "agents" is both passed in command line and then reused
inside with an input task.

Same with the properties node and node_description.

The for loop should have no trouble using properties denoted on the
command line with the -D

The -D will become a property in your ant script.

Jan,

Yeah that's what I thought would be wanted too... But I asked about the
input tasks and apparently those are needed as well. So I was sorta
confused about the whole thing.
