I am trying to use custom ANT tasks to perform JET-to-Java transformation
as specified in this jet tutorial
( http://help.eclipse.org/help33/index.jsp?topic=/org.eclipse. emf.doc/tutorials/jet2/jet_tutorial2.html)
for a sample/default JET project (with main.jet and dump.jet templates)
I have got the ANT environment setup and custom task configured and
running, but am still getting some runtime errors. My build.xml is:
<project default="jetc_multiple_templates">
<property name="eclipse.plugins.dir" location="C:\opt\eclipse\plugins" />
<taskdef name="jetc" classname="ch.paranor.epla.structure.JETCTask">
<classpath>
<pathelement location="jetc-task.jar" />
<fileset dir="${eclipse.plugins.dir}">
<!-- since there are some ClassNotFound errors, temporarely include all
eclipse .jars -->
<include name="*.jar" />
</fileset>
</classpath>
</taskdef>
<!-- Translate a bunch of template files at once. -->
<!-- You cannot use the "class" and "package" attributes when using a
fileset. -->
<target name="jetc_multiple_templates">
<mkdir dir="jet-output" />
<jetc destdir="jet-output">
<fileset dir="C:\dev\EclipseWorkspace\Jet2Java\templates\"
includes="*.*jet" />
</jetc>
<javac srcdir="jet-output" destdir="classes" />
</target>
</project>
and the error(s) that I am get are:
C:\dev\EclipseWorkspace\Jet2Java>ant
Buildfile: build.xml
jetc_multiple_templates:
[jetc] Compiling 1 JET template(s) to
C:\dev\EclipseWorkspace\Jet2Java\jet-output
BUILD FAILED
C:\dev\EclipseWorkspace\Jet2Java\build.xml:34:
java.lang.IllegalStateException: Workspace is closed.
Total time: 4 seconds
Has anyone else faced this problem? Is anyone else using this approach to
automate JET to Java transformation?

Hi Paul,
What about running the ANT buildfile straight from within Eclipse
(rightclick on build.xml->RunAs->Ant build), do I still require that Ant
Runner command line?
At the moment I'm getting this:
BUILD FAILED
...\build\build.xml:47: Problem: failed to create task or type
jet.transform
Cause: The name is undefined.
Action: Check the spelling.
Action: Check that any custom tasks/types have been declared.
Action: Check that any <presetdef>/<macrodef> declarations have taken
place.
Is there a way around this that will not require me to run a second
Eclipse instance for just this purpose?
I can see lots of questions around this topic (running JET transforms from
Ant); perhaps it would be worthy an entry in your excellent Wiki FAQ
Many thanks for all your help!
Christian
