With the grammar:

exports

context-free start-symbols
Start

context-free syntax

"module" ID Gal-expr       -> Start {cons("Module")}


(Unit-decl ".")*				-> Gal-expr {cons("GalExpr")}

Unit-type-name Unit-type-def	-> Unit-decl {cons("UnitDecl")}

ID								-> Unit-type-name {cons("UnitTypeName")}    
"a" "gal:unit" ";" Content	
	-> Unit-type-def {cons("UnitTypeDef")}

"gal:contains" "(" ( "[" ( "Attr-def" ) "]" )* ")" 
	-> Content {cons("Content")}

I get “build.generated.xml:267: Java returned 1”
While changing the last rule to:

“gal:contains” “(” ( “[" ( Attr-def ) "]” )* “)”
-> Content {cons(“Content”)}

or

“gal:contains” “(” ( “[" ( “Attr-def” ID ) "]” )* “)”
-> Content {cons(“Content”)}

(with Attr-def defined of course)

I get no errors.

That’s not good. This seems to be caused by sdf2rtg and/or rtg2sig. I’ll move this bug to the StrategoXT bug tracker.
