I just started playing around with a script task, and ran into a weird
problem.  I'm using the script in a build file that's imported into =
other
build files using the <import> task, i.e., build.xml imports import.xml =
at
the beginning of the build.xml file (right after the <project> node
opening).

Inside import.xml I've got a <macrodef> that calls the <script> task.  =
The
script task is language=3D"javascript".  I have bsf.jar and js.jar in my =
Ant
lib/.  The script is extremely simple, it's just converting a date stamp
from one format to another.

When I put a simple target in my import.xml and call my macro, and a =
execute
that target using "ant -f import.xml run-macro", everything works fine.  =
If
I make a call to that macro from build.xml, I get this error:

C:\Projects\build.xml:675: The following error occurred while executing =
this
line:
C:\Projects\import.xml:80: The following error occurred while executing =
this
line:
C:\Projects\import.xml:54: The following error occurred while executing =
this
line:
C:\Projects\import.xml:24: ConversionError: The undefined value has no
properties.

If I remove all of the lines in the JavaScript the build works (well, it
gets to the point where it needed the results of that script); if I have
just one line, and importClass statement, I get this error.

My guess is that the project context is not being passed correctly into =
the
import/macrodef/script chain, because the Script.java source has these =
lines
in execute():

	  runner.addBeans(getProject().getProperties());
        runner.addBeans(getProject().getUserProperties());
        runner.addBeans(getProject().getTargets());
        runner.addBeans(getProject().getReferences());

        runner.addBean("project", getProject());
        runner.addBean("self", this);

But I don't really know.  Anyone have any ideas?

Thanks,

- Geoff
