Question

In Ant is there any way to do something like this:

<arguments id='arg-list'>     <arg value='arg1' />     <arg value='arg2' /> </arguments>  <property name='prop1' refid='arg-list' /> 

I’m trying to write a macro for psexec and I’m looking for a nice way to pass in the argument list.

I know that you can do something similar with classpaths…

Thanks!

I don’t know of an answer to your specific question. The documentation is clear that refid ‘Only yields reasonable results for references to PATH like structures or properties.’

Without a bit more information on what you’re trying to do, it’s hard to comment. At the risk of changing your design, rather than answering your question, I suggest:

1) You can pass the argument list to exec as a line:

<macrodef name='example'>   <attribute name='args'/>   <sequential>     <exec executable='example.exe'>       <arg value='somearg' />       <arg line='@{args}'/>     </exec>   </sequential> </macrodef>  <example args='somearg arg1 arg2'/> 

Which will run example.exe:

example.exe arg1 arg2 

2) I pass in arguments to macros that call external apps like this:

<macrodef name='example'>   <element name='params' optional='yes' implicit='yes'/>   <sequential>     <exec taskname='eg' executable='example.exe'>       <arg value='somearg' />       <params />       </exec>     </sequential> </macrodef>  <example>   <arg value='arg1'/>   <arg value='arg2'/> </example> 

This will run example.exe:

example.exe somearg arg1 arg2
