Thanks a lot. That worked indeed.
I do hv another solution for this.
<project>
<property environment="env"/>
<target name="env_default" unless="env.OUTPUT_DIR">
<property name="output.dir" value="default"/>
</target>
<target name="env_check" depends="env_default">
<property name="output.dir" value="${env.OUTPUT_DIR}"/>
</target>
</project>
Many Thanks,
Janu.

Please respond to Subject
"Ant Users List" AW: Check for Env variables
<project>
<property environment="env"/>
<condition property="output.dir" value="${env.OUTPUT_DIR}">
<isset property="env.OUTPUT_DIR"/>
</condition>
<property name="output.dir" value="default"/>
<echo>output.dir=${output.dir}</echo>
</project>
1. import the environment variables with prefix "env"
2. if the OUTPUT_DIR was set, the the property output.dir to its value
3. set the output.dir to default, which only works, if not set prior.
Properties are immutable.
4. Give the output.
c:\temp>ant
Buildfile: build.xml
[echo] output.dir=default
c:\temp>set OUTPUT_DIR=other
c:\temp>ant
Buildfile: build.xml
[echo] output.dir=other
