How to fix "Syntax error:A return type must be specified for java extensions!" [message #687751]

After upgrading to Indigo, I'm getting an error message for an ".ext" file.

Syntax error:A return type must be specified for java extensions!

But the error marker doesn't seem to point to valid location. In my case, it points to a comment block (/* ... */). After changing some of the extended functions, the location changes.

What does it mean? How to fix it?

Thanks,
Raymond

Hi Raymond,

please provide the ext-file in question. Have a look for JAVA extensions
that do not specify an explicit return type and try to add one there.

Regards,
Sebastian

Hi,

I checked all the functions that are implemented in Java. All of them have a return type (such String, boolean, or Void). For example,

String getCollectionType(Reference ref) :
JAVA com.sample.generator.util.GenerationHelper.getCollectionType(com.sample.metamodel.Reference);

The java method returns String.

What am I missing here?

Please file a bugzilla with a reproducable example.

Thanks,
Sven
