Stan,
The following is from my ANT file.
<target name="init">
<property environment="env" />
<property name="isdefined" value="${env.VARNAME}"/>
<condition property="isdefined" value="default">
<equals arg1="${server}" arg2="" />
</condition>
<echo message="${server}" />
</target>
When ANT 1.4.1 is run the following is displayed
${env.VARNAME}
I would have expected an empty string to be displayed.
I am basically trying to set up properties in init
based on environment variables.
What I am trying to do is set up the build environment
based on OS environment variables. I get the value of
the variable and invoke <antcall target="${isdefined}"
/>
This way I can have handlers that are specific to the
build. The next problem that I ran into is that the
called task appears to be unable to pass back
properties to the properties.
What does the "." at the end of the environment
variable indicate ? It was unclear to me from the
docs.
Thanks.
