Subject RE: Figure out why spec. env var gets unset when gets to wrapped ant script
Date Wed, 05 Mar 2003 18:06:50 GMT
Actually, I was mistaken on one point here.  I'm finding that the
embedded ant script doesn't even have a value for "${env.JAVA_HOME}".
I'm using an "echo" task to try to print out a string containing envvar
references, and I can't seem to find any that work.  I tried
"${env.PATH}" also.

This may not matter, but I noticed an odd statement in the documentation
for the "property" task, wrt the "environment" attribute.  It says:

Note also that properties are case sensitive, even if the environment
variables on your operating system are not, e.g. it will be ${env.Path}
not ${env.PATH} on Windows 2000.

What does that mean?  Just for grins, I tried changing my test "echo"
call to reference "${env.Path}" instead of "${env.PATH}", but it still
just echoes "${env.Path}" (not the value of "$PATH").

I'm not certain exactly what version of ant they have embedded, but the
manifest of the "ant.jar" says "Created-By: Ant 1.4".
