GroovyScriptEngine fails to compile sources referring binding-scoped variables

[GoogleCodeExporter]

Just try

GroovyScriptEngine gse = new GroovyScriptEngine( new URL[] { new File( 
"[directory containing greeting.cpp]"  ).toURI().toURL() } );
Binding binding = new Binding();
binding.setVariable( "greeting", "Hello world!" );
gse.run( "test.gpp", binding );

with greeting.cpp:

System.out.println( greeting );

It will fail like this:

Exception in thread "main" 
org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
/C:/Users/Alfred/development/brt/standalone_scomp/src/main/resources/test.gpp: 
1: Cannot find property greeting of class test
 @ line 1, column 21.
   System.out.println( greeting );
                       ^

This is quite natural that static compiler can't find property it is not aware 
about.

Use something like 

System.out.println( getProperty("greeting") )

Or, you may also mark your code with @Typed(TypePolicy.MIXED) and then you 
should be able to access the binding variables as you would in core groovy.

G++ behaves as designed here. Also, 2 work-arounds suggested. Ref:
