That
explains a lot. I always thought, "that message is lying" because,
indeed, the property in the file DID get overwritten with my command
line entry. Now that I realize the error is talking about the property
statement in the file, I won't call NAnt a lier anymore. The only
reason I put in the property in the file is for a default. The message
doesn't bug me, so I'm ok with this.

Alex,
Yes, now I see what is going on. Modified the script as follows to set
a 'default' value in the event it is not specified on the command line
as such:
<?xml version="1.0"?>
<project name="TestBuild" default="default" basedir=".">
<if test="${not property::exists('TestProperty')}" >
<property name="TestProperty" value="foo" />
</if>
<target name="*">
<echo message="TestProperty = ${TestProperty}" />
</target>
</project>
This elicits the behavior that I want without the error message.
Thanks,
Ken Parrish

This also fooled me for a
long time.
The message saying "cannot
overwrite read-only property" refers to the line in the NAnt build file
trying to assign to a property that has been assigned on the
command-line, not vice versa.
That won’t
work because a property set on the command line is read-only by design.
(Overwrite
by default is already set to true anyhow.)

Hi Ken-
1) you'll need to set overwrite attribute to true e.g.
<property
name="TestProperty" value="foo" overwrite="true"/>
2)The user MUST HAVE
write privileges to the folder in which he is writing
so user fu can overwrite bar.txt

Subject: [NAnt-users] Command
line properties - Can you explain this message?
I am
setting a property from the command line. It seems to work, but I get
a message indicating that I cannot overwrite the property, yet the
property does in fact get set. Can anyone help explain this?
