Problem nesting presetdef in another task
Hello,
I created a presetdef of a <manifest> element, and then tried to use it as a sub-element of <jar>.
When I execute the script, the build fails with a message stating this is an unsupported nested element.
Here is a sample build script. In addition, to the form shown below, I have tried defining the
presetdef outside of any targets (as a direct sub-element of project),
------------------------------
<?xml version="1.0"?>
<project name="anttest" default="jar" basedir=".">
<target name="jar">
<presetdef name="my.manifest">
<manifest>
<attribute name="Built-By" value="${user.name}"/>
</manifest>
</presetdef>
<jar jarfile="anttest.jar" basedir="." includes="build.xml">
<my.manifest/>
</jar>
</target>
</project>
------------------------------
Here is the output from executing the script above:
BUILD FAILED
/java/projects/anttest/build.xml:11: The <jar> type doesn't support the nested "my.manifest" element.
Thanks for any help with this.
David

Have you watched it in the Task Manager to see if a
new java process pops up?

I'm on XP with ant 1.6.2. On verbose mode it even says "spawned process
java.lang.Win32Process@13adc56" and yet still nothing happens.

Anything's possible. :) What OS are you running on?

It just says "Build Successful" but doesn't spawn anything new. I'm
running with both verbose and debug modes. Is it possible i'm getting
errors that are preventing the spawned process but the messages aren't
getting shown in my original window?

What is or is not happening? Try executing ant in
verbose and/or debug modes, -v and -d respectively.

Java task spawn problem
Posted by Chris <ch...@branaghgroup.com>.
Hey all I'm trying to execute my application using the java task along
with "spawn=true" but it doesn't seem to be working. It seems like alot
of people have problems with the java task so i was wondering if anyone
had any ideas what i may be doing wrong?
<java classname="${class.run}" fork="true" spawn="true"
classpathref="class.path">
<arg value="verbose:jni"/>
</java>
Thanks!

Re: Problem nesting presetdef in another task
Posted by David Esterkin <de...@chariotsolutions.com>.
Antoine,
Your explanation about the two different, and incompatible, manifest tags
makes a lot of sense. I was thinking of presetdef more like an xml entity,
which is probably not the case.
Your answer also gave me an idea for a rather simple workaround. I am now
wrapping the whole jar statement inside the presetdef like the following:
<target name="jar">
<presetdef name="my.jar">
<jar>
<manifest>
<attribute name="Built-By" value="${user.name}"/>
</manifest>
</jar>
</presetdef>
<my.jar destfile="my.jar" basedir="." includes="build.xml"/>
</target>
Thanks for the help,
David

Re: Problem nesting presetdef in another task
Posted by Antoine Levy-Lambert <an...@gmx.de>.
Hello,
this sounds like a bug or a limitation of presetdef. The documentation
says that presetdef can be used with any type or task.
There is another issue which can explain the problem.
the <manifest/> tag inside a target or the body of a project is a task
used to create a manifest file.(see
http://ant.apache.org/manual/CoreTasks/manifest.html ).
the same <manifest/> tag inside <jar/> or a task derived from jar (war,
ear) instructs ant to create an inline manifest for the archive.
In this case, the <manifest/> tag refers to another Java class.
I do not know enough how presetdef is implemented and how introspection
works to figure out what is happening.
It is possible that presetdef thinks that you are referring to the
manifest task, which is globally known in ant. The manifest nested type
of jar is only known in jar and derivatives.
Cheers,
Antoine
