Hi

The Java 7 annotations for @NonNull, @Nullable were useable with Xtend.

But the equivalent Java 8 annotations report incorrect positioning of
the annotations. Is there no support or is some different usage needed
to avoid confusion with active annotations? (Using M4)

Regards

hi,

this happens in the 2.9.x release as well. can you file a bug.
looks like xtend does misscheck the

@Target({ElementType.TYPE_USE, ElementType.TYPE_PARAMETER})

target

(if i see that correct)

p.s.: which exact source/implementation for the annotations do you use (there are a bunch around)

HI

I've moved from the once official JDT Java 7 annotations (sustained as
org.eclipse.ocl.jdt.annotation7 1.0) to the official Mars M4 JDT Java 8
annotations (org.eclipse.jdt.annotation 2.0.100).

I'm just really puzzled that it doesn't work. Xtend has many Java 8
tweaks, yet it doesn't support annotations.

Regards

Er... No. I cannot find the Xtend Bugzilla component.

Perhaps Xtext, Xtend, Xpand, MWE might like to follow the
decontainerisation example of many other modeling projects so that they
are visible in

https://bugs.eclipse.org/bugs/enter_bug.cgi?classification=Modeling

Xtext at least appends itself to the TMF description but the locations
of other projects, particularly their "2" suffixes is opaque.

But not in Bugzilla. See
https://bugs.eclipse.org/bugs/enter_bug.cgi?classification=Modeling

Acceleo, OCL, Papyrus, QVTd, QVTo, Sirius etc all appear after
decontainerizing but TMF ... Xtext survives.

Ah!. Confusing. I use Xtend as distributed as parts of Xpand2 and Xtext
both of which are Modeling projects, but Xtend is not.
