Jonathan,

How would Java 8 impact what EMF generates?

I use lambda expression in EMF object and have compilation failure when I generate model from genModel

Open a bugzilla and I'll add a constant for 1.8 compliance to the
GenModel....

You might consider using Xcore instead, in which case you can uses
Xbase's Lambdas but compile them down to 1.5 compliance...

but then they are not lambdas in the Java8 sense ;-)

Tom,

It seems likely that Xbase will eventually compile to real Java lambdas,
but in the end, it all compiles down to byte code so it's only the
elegance of the source representation that seems relevant...

Of course it's not entirely clear of what's meant by "I use lambda
expression in EMF object"...

I use stream to manipulate collections.

That seem preferable for me that you add a constant for 1.8 compliance to the GenModel

Jonathan,

Do you do that in hand written code? Of course you can set JDT's
preferences for the project yourself and of course if you want Java 1.8
support from JDT, you'll need to install that too.

The problem occurred when I generate model (compilation failure)

It's not a problem in JDT (I use 4.4 - 18-03-14)

When I regenerate, if object contains hand written code with lambda, I've a compilation failure
