You might just try changing it to
if="${bldtype}"
I think that will return true if the prop exists, and false if it
doesn't.
I think you can also do:
If="${bldtype == ''}"

Subject: [NAnt-users] Re ad only Property overwriting
Hi All,
I am trying to understand the behavior and seeking help.
I am trying to run nant after specifying a property value at command
prompt. and i am trying to evaluate the property in my .build script
file
i.e
<target name="Checking_Parameters" description="Checking the parameters
for
build environment" if="${property::get-value('bldtype') != ' '}">
this line throws me an error saying "Read-only property "bldtype" cannot
be
overwritten." but in the same line if i change from "!=" to "==" the
build
runs fine.
Infact i am trying to check in the target if there is any value assigned
to
the property, and hence if there is any property the build will move
ahead
or else fail.
So wanted to know if i have missed out on something.
Thanks for your support in advance.
