gulp-sourcemap-write: source file not found: ?

[robianmcd]

When I try and uglify my code without concatenating it and then generate source maps I get an error message like:

gulp-sourcemap-write: source file not found:C:\Rob\Dropbox\Repos\gulpTest\?

my gulp task looks like this

gulp.task('js', function () {
    return gulp.src('app.js')
        .pipe(sourcemaps.init())
        .pipe(uglify())
        .pipe(sourcemaps.write())
        .pipe(gulp.dest('build'));
});

I'm using the following versions of npm modules

  "dependencies": {
    "gulp": "3.8.8",
    "gulp-uglify": "1.0.1",
    "gulp-sourcemaps": "1.1.5"
  }

There is a zipped up version of the project here https://dl.dropboxusercontent.com/u/20066539/Forum%20Links/Other/gulpTest.zip

Any idea why this isn't working?

Thanks

Seems to be a bug in gulp-uglify. It does not pass on the sources array correctly. Please report the bug there.

@floridoo we made your suggested changes to resolve exactly that… but you never replied on the ticket. We've been using vinyl-sourcemaps-apply since 1.0.0.

@terinjokes vinyl-sourcemaps-apply does not fix incomplete source maps. In the example above the source map that is passed to vinyl-sourcemaps-apply looks like this:

{"version":3,"file":"app.js","sources":["?"],"names":["test","console","log"],"mappings":"AAAA,GAAIA,MAAO,CACXA,QACAA,OACAA,OACAA,OACAA,OAEAC,QAAQC,IAAIF"}

sources is ["?"] while it should be ["app.js"] (= the input file to uglify). vinyl-sourcemaps-apply needs a valid source map to be able to work correctly.

You can fix it by setting sources to file.relative (= the input file) on the source map generated by uglify before passing it to vinyl-sourcemaps-apply.

Which ticket do you mean that I didn't reply to?
