using system environment variable within ANT?

[Alexandre�POLOZOFF � <di...@polozoff.com>]

Hello,

Sorry if this has been asked and answered but I'm new to Ant and have not
been able to find the email archives for this list.

I would like to set the build.compiler properties based on what compiler
is installed (ie; use jikes if jikes is installed).

I have a build.cmd file that sets the environment variable ANT_COMPILER to
jikes if the jikes compiler is installed. I set build.compiler to
${ant_compiler} I get an error from ant that it does not know how to use
${ant_compiler} so it is obviously not expanding my tag... how can I get
this to work?

I'm on Windows NT.

Thanks,
-Alex

You cannot access system environment variables from Java, you need to
"translate" it into a Java property. Invoking Ant with
-Dbuild.compiler=%ANT_COMPILER% should do it (I'm not sure about the
%VARIABLENAME% syntax, I'm more of a Unix guy).

It is case sensitive - try ${ANT_COMPILER}

Cheers,
