Will <fail unless="env.NO_VALUE"/> work for you? Ben

But I did my research and found no answers whatsoever. Basically I am trying to check for existence of an environment variable. And if it is not defined I want the script to fail. <project name="base" basedir="." default="echo-env"> <property environment="env"/> <target name="echo-env"> <echo>${env.NO_VALUE}</echo> </target> </project> Basically this will return "${env.NO_VALUE}". And potential <available> check will think it actually HAS value. Is there any way to make Ant recognize that System.getenv("NO_VALUE") returns null? Thank you very much beforehand, Serge. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] ************************************************************** This message, including any attachments, contains confidential information intended for a specific individual and purpose, and is protected by law.
