I found that standalone launcher, too, being playing around a bit.
The interessting part is how to determine "cp" :-)).
Does it (almost) work out-of-the-box if the build file is
processed by the Eclipse antRunner application??

Hi again,
I managed to establish the generic headless java code generation
within our continuous integration by deploying your template.
Curiously, it works for all but one bundle for a reason I absolutely don't get!
With this bundle it always fails with the following output:
[java] [java] Exception in thread "main" java.lang.NoSuchMethodError: org.eclipse.jdt.internal.compiler.batch.Main.compile([Ljava/lang/String;Ljava/io/PrintWriter;Ljava/io/PrintWriter;Lorg/eclipse/jdt/core/compiler/CompilationProgress;)Z
[java] [java] at org.eclipse.jdt.core.compiler.batch.BatchCompiler.compile(BatchCompiler.java:80)
[java] [java] at org.eclipse.jdt.core.compiler.batch.BatchCompiler.compile(BatchCompiler.java:52)
[java] [java] at org.eclipse.xtext.xtend2.compiler.batch.Xtend2BatchCompiler.preCompileStubs(Xtend2BatchCompiler.java:302)

[java] [java] at org.eclipse.xtext.xtend2.compiler.batch.Main.main(Main.java:46)
[java] [java] Java Result: 1
Since org.eclipse.jdt.internal.compiler.batch.Main and org.eclipse.jdt.core.compiler.batch.BatchCompiler are
situated in the same bundle I have no clue about it.
Tried to overcome with some memory tuning without any success.
Do you guys have any idea?

Hi Andy,
you should provide both the src and the src-gen folder to the code generator, like this:
<java classname="org.eclipse.xtext.xtend2.compiler.batch.Main classpathref="cp" >
<arg line="-d xtend-gen src:src-gen"/>
</java>
(using line is just similar to various 'value' args).
Your classpath config has to provide both the whole xtend-runtime as well as classes
used in your transformation if they aren't declared in src or src-gen.
My path definition looks like
<path id="cp">
<fileset dir="${eclipseLocation}/plugins/">
<patternset>
<include name="*antlr*.jar"/>
<include name="*/*antlr*.jar"/>
<include name="*guava*.jar"/>
<include name="*inject*.jar"/>
<include name="*icu*.jar"/>
<include name="*common*.jar"/>
<include name="*log4j*.jar"/>
<include name="*emf*.jar"/>
<include name="*jdt.co*.jar"/>
<include name="*xtext*.jar"/>
<include name="*xbase*.jar"/>
<include name="*xtend2*.jar"/>
<exclude name="*ui*.jar" />
<exclude name="*source*.jar" />
</patternset>
</fileset>
<path refid="xtend2codegen.classpath" />
</path>
whereas xtend2codegen.classpath is the path definition determined by the pde tools in
the generated plugin specific build.xml files (a copy of @dot).
Good luck,
Christian

My patience has been rewarded :-)
I integrated the codegen into our headless pde tools based build process
and re-used the generated classpath for compiling the sources.
No idea why - pde adds the org.apache.jasper bundle to the classpath.
This bundle contains org.eclipse.jdt.internal.compiler.batch.Main as well - sucker!!
Excluding this bundle from the classpath leads to success!
