You keep adding the ${} when only the property name is required.
I assure you that all you need is this - just copy and paste it and
test:
<fail unless="env.DAVINCI_EXT" message="DAVINCI_EXT environment variable
has not been set!"/>

Subject: Again: Checking for non-existence of environment variable
I think this is finally what I've been struggling with. It doesn't seem
to work when the env variable actually exists. Here is my macro:
=============================
<macrodef name="check-for-ext">
<sequential>
<echo>${env.DAVINCI_EXT}</echo>
<fail>
<condition>
<not>
<isset property="${env.DAVINCI_EXT}"/>
</not>
</condition>
Cause:
DAVINCI_EXT environment variable has not been set!
</fail>
</sequential>
</macrodef>
================================
And here is what I get trying to invoke it from basic task:
===========================================================
[EMAIL PROTECTED] ~/work/davinci-dev/davinci-master
$ echo $DAVINCI_EXT
serge
[EMAIL PROTECTED] ~/work/davinci-dev/davinci-master
$ ant -f setup-user.xml setup-home
Buildfile: setup-user.xml
setup-home:
[echo] serge
BUILD FAILED
C:\Documents and Settings\serge\My
Documents\work\davinci-dev\davinci-master\setup-user.xml:91: The
following error occurred while executing this line:
C:\Documents and Settings\serge\My
Documents\work\davinci-dev\davinci-master\setup-user.xml:201: Cause:
DAVINCI_EXT environment variable has not been set!
Total time: 0 seconds
========================================================================
I am using Cygwin on WinXP. Ant is 1.6.5.
Any ideas would be really appreciated.
Thanks again,
-Serge
