passing parameters from Ant to Unix Shell script

[Animesh Ghosh]

Hi,

I am trying to pass parameters from Ant to Unix shell scripts that
will maintain all environment variables across environments. Can you
pls. pass on a sample build.xml file and a sample shell script which
can accept parameters from the build file. I am familiar with command
line argument passing for Shell scripts but do not know well enough
about Ant scripts. Any help will be much appreciated.

I asked the same question recently!

<exec executable="bash scripts which can use myVar">
<env key="myVar" value="someValue"/>
</exec>

-- from Stefan Bodewig

or

1. you can use nested <env>s when invoking with <exec>
2. you can create the script from a template and insert the "export"
statements

Hi Animesh!

So if I need to add multiple environment properties I can keep on
adding env keys?

Yes.

What if I use parameters instead?

You can use nested <arg> elements to send paramaters to the script, but
this isn't the same as setting an environment variable.

Shall I just use
the $myVar in the Unix script?

Well, if you use nested <arg> you will only be able to use it in the
single script. If you use <env> you can it in scripts called by that too
because it is exported..
