Setting :warn-on-reflection to false doesn't work

[kumarshantanu]

Reported here: https://groups.google.com/forum/#!topic/clojure-clr/P98TZFSujb8

Also, sample.project.clj has no mention of :warn-on-reflection and :unchecked-math.

While at it, I suggest you make separate switches for reflection warnings in repl and compilation if this is feasible. e.g.
:warn-on-reflection true ;; both are true
:warn-on-reflection {:when-compiling true :in-repl false}
or soimething like that.

@akaranta The implementation seems to be alright as per this: http://clojureclr.blogspot.in/2012/01/compiling-and-loading-in-clojureclr.html -- do you have a public project where I can see why it's failing? For different behavior during compilation and REPL, Leiningen profiles should be useful, for example:

    :profiles {:cc {:clr {:warn-on-reflection true}}
               :cr {:clr {:warn-on-reflection false}}}

alternatively,

    :profiles {:cc {:warn-on-reflection true}
               :cr {:warn-on-reflection false}}

C:\work>lein with-profile cc clr compile
C:\work>lein with-profile cr clr repl

Unfortunately I don't have anything public you could use. But that does not matter - the problem is easily demonstrable by creating a new lein clr project and then compiling / starting repl on that.
I just rechecked this on a fresh project where I inserted :warn-on-reflection false in the hash under the :clr key.

Do e.g. this in repl

(def e (Exception. "foo"))
(.Message e)

and you will get a reflection warning printed.

The only changes I did was to change the clojure clr to be fetched as a dependency and to use the latest version thereof.

If you wish I can send you the project file.

I tried to reproduce this error but am not able to. One pitfall you might want to watch out for is -- when you run lein new lein-clr foo to create the project, the project.clj file is already populated (on line number 7) with :warn-on-reflection true. Make sure to edit that value, or comment that out if you add an entry later.

If the above does not impact you, please share your project.clj here or by email (mentioned here).

You were right, I had changed the :warn-on-reflection key under the :clr
hash. However, when I try to set it to false in defproject I get

I attached the project file.

@akaranta I did not receive the project.clj file. Could you please email that to me separately?

Hi,

Ok, here is the project.clj file again. I'll copy paste it inline, too, in
case there is some problem with attachments. Here:
