calling "-projecthelp"
Hello,
I'm looking for a task (or something) that makes it possible
to output the project help, as it is printed when ant is called with
"-projecthelp" option.
Background:
Usually a target "help" exists. Usually, this target prints exactly
the same as ant -projecthelp. What I need is something like this:
<target name="help">
<echo>${projecthelp}</echo>
</target>
Best regards,
Jens

How about
<target name="usage" depends="help">
<target name="help">
<echo>Run ant -projecthelp for description of targets in
project</echo>
</target>

Thank you for your hints. Of course it's possible to call
"ant -projecthelp" - but only if you know ant ;-)
I'm going to place my "help" into the build.bat/build.sh and call
"ant -projecthelp" whenever no argument is used. So, users who are not
familiar with ant get the help they need.

If you don't mind the output having [java] in front of each line, you can
use the <java> task to run Ant's Main class with -projecthelp. If you'd
rather have the output not have that, you could use <exec> and capture the
output in the "outputproperty" attribute, then <echo> that property, but
that would also involve platform-dependence. (Then again, I'm not sure
that running 'ant help' is really all that big of a win over just running
'ant -projecthelp')
