TSC errors don't make gulp build fail

[ulrichb]

Errors are ignored (even with --noEmitOnError).

Expected behavior:

• Extract GulpTypeScriptErrorRepro.zip
• npm installl
• node_modules/.bin/gulp && echo == success ==
• Exit code <> 0 (no "== success ==" output)

Actual behavior:

• Exit code == 0 ("== success ==" output)

Same on Windows/node v7.2.1; Ubuntu/node v0.10.25.

Your gulpfile:

var gulp = require('gulp');
var ts = require('gulp-typescript');

gulp.task('build', function () {
    return gulp.src('*.ts')
        .pipe(ts({
            //noEmitOnError: true,
            out: 'out.js'
        }))
        .pipe(gulp.dest('.'));
});

gulp.task('default', ['build']);

Code

class C {}
