[2.0] Problem with Javascript compilation

[Dave Gurnell]

Hi all,

I am having trouble with the following Javascript files using a very recent checkout of 2.0 (master branch, commit 6989fb99):

-- app/assets/javascripts/app.js --

goog.require('jquery');

console.log('app loaded');

-- app/assets/javascripts/jquery.js --

goog.provide('jquery');

console.log('jquery loaded');

When I execute my app with the run command and load a page, I get the following error:

[ui] $ run

--- (Running the application from SBT, auto-reloading is enabled) ---

[info] play - Listening for HTTP on port 9000...

(Server started, use Ctrl+D to stop and go back to the console...)

[info] play - Application started (Dev)

[error] {file:/Users/dave/dev/projects/egap/}ui/*:play-copy-assets: java.lang.NullPointerException

[error] application - 

! Internal server error, for request [GET /assets/js/app.js] ->

Not sure what I'm doing wrong... is this a bug in the framework?

I have a couple of comments/questions about Javascript compilation in Play that I will put in a separate post.

Best regards,

I have the same situation.

Tracking down: NLP is in closure compiler which can be fixed by
applying next patch: http://code.google.com/p/closure-compiler/issues/detail?id=672
(see attachment).

After substituted compiler.jar by patched version, it is possible to
see error message, which show that namespace module names are not the
same as subdirectories of
--common_js_module_path_prefix
