Am I completely misunderstanding the fail/unless task?

[Trent Ohannessian <to...@gmail.com>]

Hey all,

I'm trying to error the build if a command line parameter isn't passed in.
This seems simple enough but it's not working as I anticipated and I still
don't get why this isn't working after reading through several docs.  Here
is the command line call:

webtest -Denv=dev -buildfile webtest.xml

And here is the first portion of the buildfile:

<project name="InstallationCheck" basedir="." default="login">

    <fail unless="${env}" >

    Missing environment parameter.

    Here is env: ${env}

    Usage:
        webtest -buildfile webtest.xml -Denv=[dev | qa | stg | prod]
    </fail>
...

I assumed that would fail only if ${env} wasn't present.  Notice how I print
out ${env} in the failure message.  Now, here is the output when this
buildfile is run with the command line call from above:

Buildfile: webtest.xml

BUILD FAILED
D:\Open Source Projects\Canoo Web Test\my_tests\webtest.xml:3: Missing
environment parameter.

        Here is env: dev

        Usage:
                webtest -buildfile webtest.xml -Denv=[dev | qa | stg | prod]

Total time: 0 seconds

How can this be failing when when env is printed out in the failure message?

Perfect.  Thanks!

The "unless" attribute of the <fail/> task takes the name of a 
property, not its value. In this case you need to re-write the test 
as:

<fail unless="env">
   ....
</fail>
