natives/*.js missing in build/release

[cool2man]

After building the project

git clone https://github.com/plasma-umass/doppio.git
cd doppio
npm install
grunt release

I could not find the natives directory inside build/release.
This situation has changed since my last build on an older version (at the begin of September).

Without these js-files, I can't get my solution running inside browser.

I added another way to register native modules with DoppioJVM, and opted to use that method for the built-in natives to remove some startup cost.

You have two options:

• Use the new API to register a function that, when called, returns the same object you passed to registerNatives before.
• Use the old API. Re-generate listings.json by running node ./node_modules/browserfs/dist/scripts/make_xhrfs_index.js in the build directory after placing your file in the desired location.

Sorry, but I do not understand - even both options :-(

For both options I need the *.js files - but they are not be built anymore?!?
My build/release looks like:

coolbook:doppio coolman$ ls -l /Users/coolman/Development/doppio/build/release 
total 5064
lrwxr-xr-x  1 coolman  staff       41 27 Okt 10:27 classes -> /Users/coolman/Development/doppio/classes
-rw-r--r--  1 coolman  staff   397755 27 Okt 10:28 doppio.js
-rw-r--r--  1 coolman  staff  2167449 27 Okt 10:28 doppio.js.map

lrwxr-xr-x  1 coolman  staff       40 27 Okt 10:27 vendor -> /Users/coolman/Development/doppio/vendor

I am missing the folder "natives" with the (native) js-files?
In build/release-dist they still exists (inside folder source/native).

@cool2man I updated the documentation; hope it clarifies.

[cool2man]

Sorry. I didn't got it. Let us complete reset the question:

I try to use doppio in my own website using this document: https://github.com/plasma-umass/doppio/tree/master/docs

Step 0: works!

Step 1: As I don't have the generated natives/*.js any longer in in build/release, I created my web folder without them.

Step 2: On start of the virtual machine the builtin natives are missing; this results into the error: Error constructing JVM: Failed to resolve java/lang/Thread.

@cool2man In Step 1, make sure you're configuring this setting properly:

    // The first argument is the filename of the listings file
    // The second argument is the relative URL to the folder containing the listings file
    // and the data it indexes.
    // In this example, the listings file and DoppioJVM's data is at
    // <thiswebpage>/doppio/listings.json
    mfs.mount('/sys', new BrowserFS.FileSystem.XmlHttpRequest('listings.json', 'doppio'));

It's very possible that you are not passing the correct path to listings.json.
